Neural modulation enhancement using connectivity-based EEG neurofeedback with simultaneous fMRI for emotion regulation

Emotion regulation plays a key role in human behavior and overall well-being. Neurofeedback is a non-invasive self-brain training technique used for emotion regulation to enhance brain function and treatment of mental disorders through behavioral changes. Previous neurofeedback research often focused on using activity from a single brain region as measured by fMRI or power from one or two EEG electrodes. In a new study, we employed connectivity-based EEG neurofeedback through recalling positive autobiographical memories and simultaneous fMRI to upregulate positive emotion. In our novel approach, the feedback was determined by the coherence of EEG electrodes rather than the power of one or two electrodes. We compared the efficiency of this connectivity-based neurofeedback to traditional activity-based neurofeedback through multiple experiments. The results showed that connectivity-based neurofeedback effectively improved BOLD signal change and connectivity in key emotion regulation regions such as the amygdala, thalamus, and insula, and increased EEG frontal asymmetry, which is a biomarker for emotion regulation and treatment of mental disorders such as PTSD, anxiety, and depression and coherence among EEG channels. The psychometric evaluations conducted both before and after the neurofeedback experiments revealed that participants demonstrated improvements in enhancing positive emotions and reducing negative emotions when utilizing connectivity-based neurofeedback, as compared to traditional activity-based and sham neurofeedback approaches. These findings suggest that connectivity-based neurofeedback may be a superior method for regulating emotions and could be a useful alternative therapy for mental disorders, providing individuals with greater control over their brain and mental functions.

Diminished Interleukin-7 receptor expression on T-cell subsets in tuberculosis patients

Immunopathology in human tuberculosis affects T-cell phenotype and functions. Previous studies identified impaired T-cell sensitivity to Interleukin (IL)-7 accompanied by lower IL-7 receptor α-chain (IL-7Rα) expression in patients with acute tuberculosis. In the present study, we characterized affected T-cell subsets and determined the influence of tuberculosis disease severity and treatment response.Tuberculosis patients (n = 89) as well as age- and gender-matched asymptomatic contacts (controls, n = 47) were recruited in Ghana. Mycobacterium (M.) tuberculosis sputum burden was monitored prior to and during treatment. Blood samples from all patients and controls were analyzed for IL-7Rα expression and T-cell markers by multi-colour flow cytometry.CD4+ and CD8+ T-cells of tuberculosis patients showed generally lower IL-7Rα expression as compared to controls. Concomitantly, tuberculosis patients had higher proportions of naïve and lower proportions of memory CD4+ T-cells. Notably, a subset of CD27 positive central memory T-cells (Tcm), which lacked IL-7Rα expression was enriched in tuberculosis patients as compared to controls. M. tuberculosis sputum burden was not associated with differences in IL-7Rα expression. Treatment duration and response showed no clear effects although IL-7Rα expression patterns were highly variable.These results suggested generally impaired generation of memory CD4+ T-cells and enrichment of a Tcm subset without IL-7Rα expression in patients with tuberculosis.

‘Let there be light’ or life in the dark? Vital geographies of mental healthcare

This paper explores the relations between light and dark/white and black disclosed in a study of Gartnavel Royal Hospital in Glasgow, Scotland, where an old Victorian lunatic asylum remains, if becoming ruined, on the same site as a modern mental healthcare campus. In-depth interview work recovering the ‘spatial stories’ of patients and staff, past and present, reveals a complex mixture of positive and negative memories and interpretations prompted by both the ‘darkened spaces’ of Old Gartnavel and the liveliness associated with both sets of spaces. These findings are framed by (a) a reading of Badiou's short monograph on Black (Badiou, 2017) and (b) an engagement with light and dark studies, both of which suggest a rebalancing of the normal valuations whereby dark/black is cast as the realm of death, everything that deadens and threatens life, whereas light/white is cast as that of life, liveliness and vitality. The scholarship here speaks to work on vitalist health geographies, agreeing that vital health-worlds can surface almost anywhere, but reminding that the fragility of such worlds can always be threatened by too much over-ordering.

Patients' recollections of helmet-CPAP treatment during COVID-19 pandemic: A qualitative study.

During the pandemic outbreak, helmet continuous positive airway pressure (CPAP) was widely used as respiratory support for COVID-19 patients, inside and outside of intensive care units. The available literature suggests specific interventions to improve the comfort of patients treated with helmet-CPAP. Few reports are available on the experiences of patients undergoing this treatment. This qualitative study aimed to explore the views and recollections of COVID-19 patients undergoing helmet-CPAP. We conducted semi-structured interviews with thematic analysis. Participants were recruited from the follow-up programme for COVID-19 patients discharged from an Italian general intensive care unit. Participants were interviewed by telephone. Data analysis followed the principles of thematic synthesis approach. We conducted 29 phone calls in patients eligible for the study. Five participants declared that they did not remember the time spent in hospital on helmet-CPAP. Twenty-four patients were then included. Two themes and six subthemes were generated from their interview data: (1) The helmet-CPAP as a life-saving treatment (subthemes: recognition of the usefulness of treatment and resilience); (2) the negative feelings related to helmet-CPAP application (subthemes: communication problems, entrapment, mental confusion, fear of dying). Each patient's experience was unique, but some discomfort elements such as noise, gas flow turbulence, choking sensation and thirst were found to be very common. The application of helmet-CPAP treatment generated positive and negative memories and feelings in COVID-19 patients during the pandemic. The patients' experience has provided an overview of the main factors of discomfort. This can be a starting point for taking corrective measures to promote greater helmet tolerance and subsequent treatment success. This study has provided an insight into the patient's recollections about helmet-CPAP treatment during a worldwide pandemic. The findings suggested strict applications of interventions aimed to reduce some issues that participants reported, to improve their compliance to treatment. Results from this study could help nurses in understanding the needs of patients treated with helmet-CPAP and may foster a care focused on patient-centred outcomes.

A Meta-Analysis of the Influence of Cue Valence on Overgeneral Memory and Autobiographical Memory Specificity Among Youth.

Overgeneral memory (OGM), or difficulty recalling specific memories when recounting autobiographical events, is associated with psychopathology. According to functional avoidance theory, OGM-or reduced autobiographical memory specificity (AMS)-may serve as an emotion regulation strategy that aids in the avoidance of painful, negative memories (Sumner,2012; Williams et al., 2007). Some researchers argue that there may be a valence effect for OGM, such that there is a higher frequency of overgenerality when recalling negative memories compared to positive memories. Although not supported among adults, valence effects may be present among children and adolescents if OGM initially develops in response to negative cues and then generalizes to all memory recall over time. This meta-analysis examined differences in child and adolescent OGM and AMS based on cue valance; standardized mean differences between negative and positive valence cues for OGM and AMS indices were calculated. Following PRISMA guidelines, a systematic literature search resulted in 26 studies assessing OGM and 30 assessing AMS. There was a significant effect of valence on OGM (d = 0.17, p = 0.01) and AMS (d = -0.20, p = 0.01). There was a higher frequency of overgeneral responses to negative cue words than positive cue words. Similarly, there was a higher frequency of specific responses for positive cue words than negative cue words. Subgroup analyses considering differences in valence effects by participant age (childhood vs. adolescence), sample type (clinical vs. community), and task instructions (verbal vs. written) were not significant. Theoretical advancements for our understanding of OGM and AMS and clinical implications are discussed.

Enhanced efficacy of CBT following augmentation with amygdala rtfMRI neurofeedback in depression

BackgroundDespite cognitive behavioral therapy (CBT) being a standard treatment in major depressive disorder (MDD), nearly half of patients do not respond. As one of the predictors of CBT's efficacy is amygdala reactivity to positive information, which is often decreased in MDD, we explored whether real-time fMRI neurofeedback (rtfMRI-nf) training to increase amygdala responses during positive memory recall prior CBT would enhance its efficacy. MethodsIn a double-blind, placebo controlled, randomized clinical trial, 35 adults with MDD received two sessions of rtfMRI-nf training to increase their amygdala (experimental group, n = 16) or parietal (control group, n = 19) responses during positive memory neurofeedback prior to receiving 10 CBT sessions. Depressive symptomatology was monitored between the rtfMRI sessions, the first three, 9th and 10th sessions of CBT and at 6 months and 1 year follow-up. ResultsParticipants in the experimental group showed decreased depressive symptomatology and higher remission rates at 6 months and 1 year follow-up than the control group. Analysis of CBT content highlighted that participants in the experimental group focused more on positive thinking and behaviors than the control group. LimitationsThe study was relatively small and not sufficiently powered to detect small effects. ConclusionsCBT, when combined with amygdala neurofeedback, results in sustained clinical changes and leads to long-lasting clinical improvement, potentially by increasing focus on positive memories and cognitions.

Investigating traumatic memory integration in people with and without post-traumatic stress disorder using the event-cueing paradigm

ABSTRACT Poor integration and landmark views make opposing claims regarding the relationship between post-traumatic stress symptoms and trauma memory integration. This study tested these approaches using an event cluster paradigm. In total, 126 participants (N ptsd = 61; N non-ptsd = 65) remembered memories from the same story as trauma, positive and neutral memories and reported whether each memory was directly retrieved or generated. Moreover, the retrieval time (RT) was recorded. Finally, the participants completed the Centrality of Event Scale (CES) and Post-traumatic Stress Disorder Symptom Scale-Self Report (PSS-SR). The results demonstrated that participants with post-traumatic stress disorder (PTSD) recalled their clusters of memories more slowly and less directly than those without PTSD. However, the CES predicted PTSD severity more strongly than RT and retrieval strategy. These results suggest that traumatic memories are more disorganised but perceived as more central in PTSD.

Cultural Identity and Historical Nostalgia in Animated Film

This article examines the aspects and implications of nostalgia and historical nostalgia in animated films, based on the case study of the 2001 Hong Kong animation My Life As McDull, directed by Toe Yuen. The investigation includes three components: a discussion around the notion of historical nostalgia, a survey of professional animators with the audience’s expectations and its perception of animated films, and an analysis of the mechanisms the movie utilizes to address the concepts of shared memory, local culture and sense of identity. The paper establishes connections between the animation’s visual elements, the notion of positive memory, and their socio-cultural implications. The results present data findings, as well as an analysis of the cinematic effects of conceptual and aesthetical processes to induce nostalgia through storytelling, concluding with their cultural and social resonance.

Exploring the cognitive context of gratitude to God: emotional impact and appraisals of benefits from God

ABSTRACT In two pre-registered studies we investigated the cognitive context of gratitude to God (GTG) and fading positive affect of grateful memories. Although gratitude has been shown to causally impact happiness, few studies have investigated how the nature of the benefactor might affect experienced gratitude. Participants first recalled a positive event, a human-caused benefit, or a God-caused benefit. After recall they reported their current momentary emotions, recalled past emotions from the time of the event and emotion appraisals. Grateful memories showed less fading positive affect over time compared to other positive memories. Appraisals of value and altruism predicted both GTG and gratitude to humans (GTH). Positive spiritual appraisals (e.g. positive interpretations about one’s relationship with God, the sacred giftedness of the event) were uniquely associated with GTG. When it comes to felt gratitude, the nature of the benefactor does matter.

Powrót do przeszłości V: pandemia. Nostalgia a świat postpandemiczny

One of the phenomena which scope expanded during the period of restrictions related to COVID-19 was a social turn towards the past, observed especially in social media, identified as a nostalgia trend. Understood as a sentimental longing for something that has already passed that causes sadness or pleasure by remembering something and wishing it could be experienced again, nostalgia was one of the tools for dealing with the hardships and uncertainty of the pandemic times. Individual users of social media willingly undertook communication focused around memories, expressing regret for times long gone that had been seen in their idealized form as easier and happier. This trend has been effectively used in marketing focused on nostalgia. It was only effective when it evokes positive memories and evokes good feelings in the recipients that encourages the more to reach for the product or service offered. This specific turn towards this period of time was used as a tool that allowed not having to face terrifying moments and often difficult present, and even more so the unknown future. Thus, uncertain of the future and terrified of the present, the pandemic consumer was all the more susceptible to peaceful and happy images from the past, which both algorithms and commercial entities gave him. In these circumstances, one can point to a specific management of pandemic nostalgia by entities that are essentially external to the individual user.

The memory of Sulla in Ephesus

In this brief paper, we focus on the monument of C. Memmius and its inscription in Ephesus in western Turkey. C. Memmius was the grandson of Sulla and was mentioned in the inscription of this Ephesian monument as the epigraph of the dedicatee. After discussing the monument’s function, dating and inscription from different perspectives, in the concluding part, we refer to the positive memory of Sulla in Asia Minor, especially in Ephesus.

Narrative Health: Examining the relationship between the phenomenon of awe and resilience and well-being

Research has shown that experiencing awe can support people’s well-being and enhance their resilience. A secondary phenomenological analysis was conducted of data collected from the Awe Project, a 5-day, online resilience program. Based on the existing literature, which demonstrates that reflecting on positive memories can support individuals’ well-being, a practice during the Awe Project prompted participants first to define awe and then to share a personal awe experience. The results indicated that many of the participants’ awe definitions and narratives were consistent with themes relating to previous awe research while new awe-related themes also emerged. Additionally, many of the awe definitions and stories included elements relating to resilience practices such as cognitive reappraisal, connectedness, gratitude, meaning and purpose in life, mindfulness, and self-efficacy. The results indicated that explaining awe and sharing awe narratives can potentially support people’s well-being, and that being exposed to awe narratives may support this as well.

Soundscapes, music, and memories: Exploring the factors that influence emotional responses to virtual nature content

From walking through a park to sitting on a beach, much is known about the therapeutic potential of direct contact with natural environments. Yet routinely in the UK, millions of people encounter nature in a completely different way: through their television screens. Despite the ubiquity of natural history programming, little is understood about its impact on the restorative and affective experiences of audiences. Nowhere is this truer than in the bold orchestral scores that accompany almost all nature documentaries. Whilst considerable evidence suggests that separately, both nature and music can provide a range of psychological benefits, how their pairing might affect the wellbeing potential of virtual nature encounters remains largely unknown. Similarly, scant research has considered how viewers’ own experiences, recalled through memories, might influence outcomes. To explore these areas, we formed a transdisciplinary broadcast initiative, called BBC Soundscapes for Wellbeing. Part of this project involved a randomized and controlled experiment that presented participants (n = 7636) with a dynamic nature scene accompanied by one of four acoustic tracks. Results demonstrated that whilst adding music to this scene led to increased feelings of excitement, it led to no other restorative or affective benefits when compared to silence. In contrast, the addition of natural sounds was associated with greater feelings of restorative potential, calmness, and excitement. Natural sounds also drove significant increases in the complex emotions of awe and nostalgia. Crucially, results showed the substantial moderating effects of participant memories. Those with positive memories stimulated by the experience reported significantly greater effects across all conditions and dependent variables. We find that although the acoustic design of virtual nature encounters can affect a range of emotional responses, the memories triggered by these experiences may be far more important for predicting viewer outcomes.

Toward a computational understanding of how reminiscing about positive autobiographical memories influences decision-making under risk.

Recent computational psychiatric research has dissected decision-making under risk into different underlying cognitive computational constructs and identified disease-specific changes in these constructs. Studies are underway to investigate what kind of behavioral or psychological interventions can restore these cognitive, computational constructs. In our previous study, we showed that reminiscing about positive autobiographical memories reduced risk aversion and affected probability weighting in the opposite direction from that observed in psychiatric disorders. However, in that study, we compared positive versus neutral memory retrieval by using a within-subjects crossover posttest design. Therefore, the change of decision-making from baseline is unclear. Furthermore, we used a hypothetical decision-making task and did not include monetary incentives. We attempt to address these limitations and investigated how reminiscing about positive autobiographical memories influences decision-making under risk using a between-subjects pretest posttest comparison design with performance-contingent monetary incentives. In thirty-eight healthy, young adults, we found that reminiscing about positive memories reinforced the commonly observed inverted S-shaped nonlinear probability weighting (f = 0.345, medium to large in effect size). In contrast, reminiscing about positive memories did not affect risk aversion in general. Given that the change in probability weighting after reminiscing about positive memories is in the opposite direction from that observed in psychiatric disorders, our results indicate that positive autobiographical memory retrieval might be a useful behavioral intervention strategy for amending the altered decision-making under risk in psychiatric diseases.

Жіночий досвід у перинатальному періоді

Perinatal experience is an important stage in the life of every mother and her child. The childbirth process can be a source of emotional satisfaction and strengthen the bond between the mother and the newborn baby. However, a negative childbirth experience can create feelings of fear towards future deliveries, the need for cesarean section, the risk of developing post-traumatic stress and postpartum depression, as well as problems with breastfeeding. Purposе - to study the level of women’s satisfaction with childbirth in order to improve perinatal care. Materials and methods. A prospective cohort study was conducted involving 321 mothers who completed the satisfaction scale for childbirth and delivery. Descriptive statistics were utilized for data analysis. It was found that the data distribution deviates from the normal distribution. The median value (Me) and the interquartile range (Q I - Q III) were calculated for the dataset. Results. The satisfaction scale helped identify the advantages and disadvantages of the childbirth experience in four key aspects of vaginal delivery. 1. Own capacity: a) Advantages: 76% of women felt strong; 79.3% - felt confident; 67.4% - felt happy. b) Disadvantages: 54% - felt that their childbirth experience matched their plans; 76.2% - felt tired. 2. Professional support: a) Advantages: 86.8% - felt they received sufficient attention and information from their caregivers; 84.8% - felt a comfortable and warm atmosphere; 84.8% - felt their needs were understood; 89.3% - felt they received proper care and assistance; b) Disadvantages: None, as the majority of women felt satisfied with the professional support. 3. Perceived safety: a) Advantages: 86% - felt safe; 89% - had trust in the professional abilities of the healthcare team; 68% - had many positive memories, while 1% had many negative memories; b) Disadvantages: 31% - experienced a low level of anxiety, while 16% - experienced a high level of anxiety. 4. Participation: a) Advantages: 67% - had the opportunity to choose a pain relief method; 60% - had the opportunity to change positions, while 21% did not; 86% - felt they received sufficient attention and information from the medical team; b) Disadvantages: Some women did not have the opportunity to choose a pain relief method (33%) or change positions during childbirth (21%). Conclusions. The study of women’s satisfaction with childbirth indicated the need for improvement in the aspect of «perceived safety». «Own capability», «professional support», and «participation» demonstrate high satisfaction, indicating the quality of perinatal care. The level of satisfaction can become a key indicator of the quality of perinatal care, contributing to the improvement of hospital efficiency assessment and quality of medical services». The study was conducted in accordance with the principles of the Helsinki Declaration. The research protocol was approved by the Local Ethical Committee of the institution specified in the work. Informed consent for participation in the study was obtained from the women. No conflict of interests was declared by the authors.

Festive nostalgia in COVID-19: an empirical investigation

ABSTRACT The COVID−19 pandemic has reinforced the importance of positive memories. Therefore, our study develops a measurement instrument for festive nostalgia, composed of seven dimensions and measured through 28 items. A rigorous scale development process was adopted and validated through two main studies. While a convenience sample (303 participants) was used to assess the initial validity through exploratory factor analysis, a final sample of 412 respondents was used to assess the second-order factor structure of festive nostalgia through CFA and structural equation modelling. Findings suggest festive nostalgia can significantly predict intention to recommend and revisit intentions. Also, the study suggested that festive nostalgia is manifested through festivals, festive experience, festive environment, festive socialization, festive identity, cultural identity and festive activity involvement. Based on the findings, managers of festive destinations can formulate strategies to draw tourists willing to participate in festivals and develop the attractiveness of such destinations.

Foundations of the Positive Affect Tolerance Protocol: The Central Role of Interpersonal Positive Affect in Attachment and Self-Regulation

Research has highlighted the negative effects of early neglect and abuse on the development of emotional self-regulation and attachment. Attention has focused more on negative affect states related to past adverse and traumatic experiences than on the deactivating effects of the absence of early shared positive affect states from parent-infant play, warmth, and affection. Treatment strategies for survivors of early neglect and abuse have focused on methods to metabolize memories of traumatic events. Skills development models have emphasized the benefits of distress tolerance, acceptance, and mindfulness training for patients with persistent negative affect states. Research on the benefits of therapeutic interventions intended to increase positive affect indicates they promote prosocial behaviors and creativity, broaden the scope of attention, reduce emotional symptoms and behavioral problems, and improve physical health. Within the field of eye movement desensitization and reprocessing (EMDR) therapy, procedures to increase positive affect have generally focused on resource development and installation procedures intended to increase access to positive affect-related memories and images. A neglected clinical issue is the inability of survivors of early neglect to tolerate and integrate actual positive interpersonal experience into positive emotional states, interpersonal scripts, or self-concepts. These deficiencies, characteristic of those with dismissing insecure attachment, help produce and maintain profound psychological, medical, and social problems that limit the ability of patients with these histories from progressing in psychotherapy. This article explores research supporting the potential benefits of an EMDR-related procedure, the positive affect tolerance (PAT) and integration protocol, along with possible mechanisms by which the PAT protocol in general, and its bilateral stimulation procedures, might produce clinical benefits for survivors of early neglect. Case vignettes illustrate the potential challenges of implementing and the potential impact of the PAT protocol. Research designs and assessment tools are described that could clarify the potential benefits of the PAT protocol compared to other treatments designed to increase positive affect.

Long-term, multi-event surprise correlates with enhanced autobiographical memory.

Neurobiological and psychological models of learning emphasize the importance of prediction errors (surprises) for memory formation. This relationship has been shown for individual momentary surprising events; however, it is less clear whether surprise that unfolds across multiple events and timescales is also linked with better memory of those events. We asked basketball fans about their most positive and negative autobiographical memories of individual plays, games and seasons, allowing surprise measurements spanning seconds, hours and months. We used advanced analytics on National Basketball Association play-by-play data and betting odds spanning 17 seasons, more than 22,000 games and more than 5.6 million plays to compute and align the estimated surprise value of each memory. We found that surprising events were associated with better recall of positive memories on the scale of seconds and months and negative memories across all three timescales. Game and season memories could not be explained by surprise at shorter timescales, suggesting that long-term, multi-event surprise correlates with memory. These results expand notions of surprise in models of learning and reinforce its relevance in real-world domains.

Impacts of repeated retrieval of positive and neutral memories on posttrauma health: An investigative pilot study

Background and objectivesEvidence indicates that positive memory processes play a role in the etiology and maintenance of posttraumatic stress symptoms (PTSS) and related posttrauma health indicators. To extend this research, the current pilot study examined if repeated retrieval of positive vs. neutral memories was associated with (1) less PTSS and depression severity; and (2) improved affect and cognitions (fewer posttrauma cognitions, more positively-valenced affect, less negatively-valenced affect, less negative affect interference, less anhedonia, retrieval of more positive specific memories, retrieval of fewer negative specific memories). MethodsTwenty-five trauma-exposed participants were randomly assigned to a positive or neutral memory task condition. They participated in four weekly experimental sessions facilitated by an experimenter virtually; each consecutive session was separated by 6–8 days. We conducted mixed between-within subjects ANOVAs to examine study hypotheses. ResultsNo interaction effects were significant. There were significant main effects of time on PTSS and depression severity, posttrauma cognitions, positively-valenced and negatively-valenced affect, and negative affect interference. LimitationsWe used self-report measures, small and non-clinical sample with limited demographic diversity, and virtual format; did not record memory narratives; and did not have a trauma memory condition. ConclusionsBased on pilot data, our findings suggest that individuals who retrieve positive or neutral memories repeatedly may report less PTSS and depression severity, fewer posttrauma cognitions, and improved affect. Results provide an impetus to examine impacts of and mechanisms underlying memory interventions (beyond a sole focus on negatively-valenced memories) in trauma work.

“I’m just not feeling it”: Affective processing of episodic physical activity memories differs between physically active and inactive individuals

Despite widespread awareness of the physiological and psychological benefits of physical activity, many individuals do not meet recommended guidelines. The current research investigated whether episodic memories of physical activity experiences and the emotions elicited by such memories differ between active and inactive individuals. A total of 40 active individuals (36 females, 4 males; Age X‾ = 20.40) and 36 inactive individuals (31 females, 5 males Age X‾ = 22.67) were asked to retrieve positive and negative memories of physical activity experiences and to rate them for phenomenological characteristics such as vividness, coherence, remembered emotion, and the emotions elicited when recalling those experiences. There was no difference between the active and inactive individuals in the remembered emotion of negative physical activity memories, but the positive memories recalled by active individuals were rated as more positive than those recalled by inactive individuals. The memories recalled by active individuals also elicited ‘in the moment’ emotions that were more positive for positive memories, and less negative for negative memories, compared to those recalled by inactive individuals. The findings are in line with hedonistic theories of physical activity engagement and suggest that futher research exploring the role of physical activity memories, and their associated affective processing, is warranted.
