ECMO Survivors' Reflections on Their ICU Experience and Recovery.

As pediatric mortality improves, approaches to pediatric critical care now focus on understanding long-term implications of survivorship on patients and families. We aimed to characterize how patients recall time spent sedated and recovering to identify areas for improvement in patient outcomes. We undertook qualitative analysis using semistructured interviews of pediatric patients requiring extra-corporeal support in our intensive care units from 2018 to 2023. All patients were English-speaking, >12 years old at time of hospitalization, and able to communicate at an age-appropriate level. Priority sampling was given to those with more recent hospitalizations to improve recall. Interviews were recorded and transcribed before thematic, inductive analysis. Forty-one patients met inclusion criteria; 14 patients were enrolled before achieving thematic saturation. Several themes emerged, centering on cognitive, physical, and socioemotional experiences during and after hospitalization. Notable findings include profound awareness under sedation, impaired sleep, challenges with communication, physical discomfort, frustration with activities of daily living limitations, and gratitude for provider and family presence. Postdischarge, patients highlighted persistent memory, concentration, sleep, and physical impairments, as well as emotional processing of their illness and mortality. Our findings describe how pediatric critical illness impacts short and long term cognitive, physical, and socioemotional outcomes for children in the ICU. Future research is necessary to study if there are specific, modifiable factors in patients' care that impacts their experience of critical illness, such as specific medication choices, diagnoses, communication styles, or physical and speech therapy interventions.

Role of Microstructural White Matter Changes of Somatosensory Cortex in Stress Among Non-Clinical Population: A Diffusion Tensor Imaging Study

Introduction: Stress is a common response to stressors or potential threats, resulting in physical, affective, and cognitive changes. Emotions are linked to interpretations of bodily alterations, with the somatosensory cortex, including the postcentral gyrus, playing a key role in emotional processing. This study aimed to investigate the relationship between stress and microstructural white matter changes in the somatosensory cortex among healthy adults, crucial for early detection and treatment of stress in non-clinical populations. Materials and Methods: A total of 30 participants were recruited. The participants were administered the Depression, Anxiety, and Stress Scale 21 (DASS-21) questionnaire. All subjects underwent MRI brain scanning, with diffusion tensor imaging (DTI) used to assess white matter integrity. The association between stress scores in DASS-21 and DTI parameters was analyzed. Results: A significant negative correlation between stress scores and fractional anisotropy (FA) values in the left postcentral gyrus (r = -0.393, p = 0.32) was found, indicating early impairment by stress. No significant correlation was found in the right postcentral gyrus (r = -0.300, p = 0.107). Conclusion: Our research results demonstrated that the microstructural somatosensory cortex, especially the left postcentral gyrus, might have early changes impairment by stress using the technique of diffusion tensor imaging (DTI). Therefore, the microstructural white matter changes in the brain before suffering the disorder may be crucial and can be a novel potential biomarker for the early detection and intervention of the disease in the non-clinical population.

Longitudinal relationships between emotional processes and perceived performances among athletes: The moderating effect of emotional intelligence

ObjectivesBased on emotional intelligence (EI) theory and cognitive motivational relational theory of emotions, this study aimed to explore longitudinal relationships between the core constructs of the emotional process (appraisals, coping and emotions) and perceived performances during competition and to examine the moderating role of EI on these relationships. MethodsA total of 453 athletes (Mage= 20.6; 117 females and 336 males) from different sports and different competitive levels participated in the study. Appraisals, coping, emotions, and perceived performances were assessed after five competitions across the season and EI was assessed at the beginning of the competitive season. Hierarchical linear modelling analyses were conducted to: (a) Evaluate the mediational role of coping strategies on the appraisals – emotions relationships and on the appraisals – perceived performances relationships; (b) explore the mediational role of emotions on the appraisals – perceived performances relationships; and (c) test the moderating role of EI on these relationships. ResultsThe results showed that: (a) coping played a mediational role on the appraisals-emotions relationships; (b) emotions mediated the appraisals-perceived performances relationships; and (c) EI moderated the aforementioned relationships between the core constructs of emotional process and perceived performances. ConclusionsAs a whole, this study furthered knowledge about the ways the core emotional constructs are interrelated and impact perceived performances within competitive settings. Through coping strategies and cognitive appraisals, EI was associated with higher intensity of pleasant emotions and perceived performances. As an applied implication, we encourage sport psychologists and coaches to provide training programs aimed at enhancing EI.

Theory of affective pragmatics under biolinguistics.

This paper introduces a pioneering investigation into affective pragmatics through the perspective of Darwinian Biolinguistics, an interdisciplinary field at the nexus of biological and linguistic principles. Anchored in Darwin's theory of evolution and the latest developments in neurobiology, this study delves into the influence of biological factors---especially those pertaining to the brain's emotional processing on pragmatic communication. The research posits that human emotional responses, inherent in our biological constitution, profoundly influence the usage and interpretation of language in social interactions.

History of Peripartum Depression Moderates the Association Between Estradiol Polygenic Risk Scores and Basal Ganglia Volumes in Major Depressive Disorder

The neurobiological differences between women who have experienced a peripartum episode and those who have only had episodes outside of this period are not well understood. 64 parous female patients with major depressive disorder that have either a positive (n=30) or negative (n=34) history of peripartum depression (PPD) underwent MRI acquisition to obtain structural brain images. An independent two-sample t-test comparing patients with and without a history of PPD was performed using voxel-based morphometry analysis (VBM). Additionally, polygenic risk scores (PRSs) for estradiol were calculated and a moderation analysis was conducted between 3 estradiol PRSs and PPD history status on extracted cluster volumes using IBM SPSS PROCESS macro. The VBM analysis identified larger grey matter volumes in bilateral clusters encompassing the putamen, pallidum, caudate, and thalamus in patients with PPD history compared to patients without a history. The moderation analysis identified a significant interaction of 2 estradiol PRSs and PPD history on grey matter cluster volumes with a positive effect in PPD women and a negative effect in women with no history of PPD. Our findings demonstrate that women who have experienced a peripartum episode are neurobiologically distinct from women who have no history of PPD in a cluster within the basal ganglia, an area important for motivation, decision-making, and emotional processing. Furthermore, we show that the genetic load for estradiol has a differing effect in this area based on PPD status which supports the claim that PPD is associated with sensitivity to sex steroid hormones.

Multimodal imaging of the amygdala in non-clinical subjects with high vs. low autistic-like social skills traits

Recent clinical and theoretical frameworks suggest that social skills and theory of mind impairments characteristic of autism spectrum disorder (ASD) are distributed in the general population on a continuum between healthy individuals and patients. The present multimodal study aimed at investigating the amygdala's function, perfusion, and volume in 56 non-clinical subjects from the general population with high (n=28 High-SOC) or low (n=28 Low-SOC) autistic-like social skills traits. Participants underwent magnetic resonance imaging to evaluate the amygdala's functional connectivity at rest, blood perfusion by means of arterial spin labelling, its activation during a face evaluation task and lastly grey matter volumes. The High-SOC group was characterised by higher blood perfusion in both amygdalae, lower volume of the left amygdala and higher activations of the right amygdala during processing of human faces with fearful value. Resting state analyses did not reveal any significant difference between the two groups. Overall, our results highlight the presence of overlapping morpho-functional alterations of the amygdala between healthy individuals and ASD patients confirming the importance of the amygdala in this disorder and in social and emotional processing. Our findings may help disentangle the neurobiological facets of ASD elucidating aetiology and the relationship between clinical symptomatology and neurobiology.

Differential effects of mindfulness treatment and mobile neurofeedback on event-related potentials in early posterior negativity in cancer patients: a clinical-experimental parallel group design.

Cancer frequently leads to psychological challenges, among them emotion regulation problems. These can be alleviated with the help of mindfulness therapies or neurofeedback (NF) interventions. Possible intervention effects on emotion procession can be detected in clinical EEG studies by exploring event-related potentials, e.g., early posterior negativity (EPN), which recently has been established to investigate emotional processing and represents very early attention to affective stimuli. Therefore, this clinical-experimental study investigated the efficacy of mindfulness and NF (10 sessions each) on the EPN in oncology patients. The study enrolled 42 cancer patients (age: 31-73 years; gender: 28 female, 14 male). The study design was an RCT with a parallel group [NF (n = 21) versus mindfulness (n = 21)] waitlist paradigm. EEG recordings in an oddball task with neutral, rare positive and negative valence and high and low arousal stimuli were performed at three measurement time points (T0 = before waitlist, T1 = before intervention, T2 = after intervention). Following preprocessing, data from electrodes O1, Oz and O2 were analyzed for EPN amplitudes. Response time did not differ across groups and conditions. Comparing EPN at T1 and T2, there was a significant interaction of time, valence, and intervention (p = 0.042). Descriptive statistics showed increased EPN for negative stimuli after the NF intervention (T1 to T2), while EPN for positive stimuli only slightly increased. For mindfulness, positive stimuli evoked stronger amplitudes after the intervention, while EPN for negative stimuli increased from T1 to T2. Distinct effects were observed for the EPN for pictures with negative valence. Here, it is presumed that mindfulness treatment led to a refocusing of attention with a focus on positive valence, whereas NF seems to entail a different processing of images with negative valence and is therefore to be seen more in the sense of a confrontational approach. Our results suggest that both interventions are suitable for modulating EPN. However, it is not clear to what extent the effects are due to the interventions alone and how other factors might have affected the amplitudes, which highlights the need for further research in this area.

Neural Representations of Emotions in Visual, Auditory, and Modality-Independent Regions Reflect Idiosyncratic Conceptual Knowledge.

Growing evidence suggests that conceptual knowledge influences emotion perception, yet the neural mechanisms underlying this effect are not fully understood. Recent studies have shown that brain representations of facial emotion categories in visual-perceptual areas are predicted by conceptual knowledge, but it remains to be seen if auditory regions are similarly affected. Moreover, it is not fully clear whether these conceptual influences operate at a modality-independent level. To address these questions, we conducted a functional magnetic resonance imaging study presenting participants with both facial and vocal emotional stimuli. This dual-modality approach allowed us to investigate effects on both modality-specific and modality-independent brain regions. Using univariate and representational similarity analyses, we found that brain representations in both visual (middle and lateral occipital cortices) and auditory (superior temporal gyrus) regions were predicted by conceptual understanding of emotions for faces and voices, respectively. Additionally, we discovered that conceptual knowledge also influenced supra-modal representations in the superior temporal sulcus. Dynamic causal modeling revealed a brain network showing both bottom-up and top-down flows, suggesting a complex interplay of modality-specific and modality-independent regions in emotional processing. These findings collectively indicate that the neural representations of emotions in both sensory-perceptual and modality-independent regions are likely shaped by each individual's conceptual knowledge.

Neural correlates of pain acceptance and the role of the cerebellum: Functional connectivity and anatomical differences in individuals with headaches versus matched controls.

Despite functional connectivity network dysfunction among individuals with headaches, no studies have examined functional connectivity neural correlates and anatomical differences in coping with headaches. This study investigated inter-individual variability in whole-brain functional connectivity and anatomical differences among 37 individuals with primary headaches and 24 age- and gender-matched controls, and neural correlates of psychological flexibility (PF) that was previously found to contribute to headache adjustment. Participants (84% women; M headache severity = 4/10; M age = 43 years) underwent functional magnetic resonance imaging scans and completed questionnaires to examine global and subnetwork brain areas, and their relations with PF components, controlling for age, gender, education, and head-motion. Seed and voxel-based contrast analyses between groups showed atypical functional connectivity of regions involved in pain matrix and core resting-state networks. Pain acceptance was the sole PF component that correlated with the cerebellum (x, y, z: 28, -72, -34, p-false discovery rate <0.001), where individuals with headaches showed higher grey matter density compared to controls. The cerebellum, recently implicated in modulating emotional and cognitive processes, was indicated to process information resembling what individuals do when practicing pain acceptance. Our findings establish for the first time this connection of the cerebellum and its role in pain acceptance. We propose that pain acceptance might be a behavioural biomarker target that could modulate problematic headache perceptions and brain networks abnormalities. This study highlights the potential use of emerging behavioural biomarkers in headache management, such as pain acceptance, and their role in modifying the headache experience. Notably, grey matter reorganization in the cerebellum and other known brain pain networks, could indicate brain networks that can be modified from targeted behavioural interventions to help decode the nociplastic mechanisms that predominates in headaches.

Echoes of violence: experiences of Palestinian Arab students in Israeli academia during the violent events of May 2021

AbstractThis paper investigates the challenges faced by Palestinian Arab citizens of Israel (PAI) who are students in Israeli higher education institutions amidst periods of national turbulence and violence, particularly focusing on the violent events of May 2021. Using interviews with students, academics, and members of civil society organisations, the paper puts forth a constructivist grounded theory model that charts the impact of the violent events of May 2021 on PAI students. It reveals that students’ experiences of violence, in various forms, give rise to a host of emotional, social, and political processes that heighten their awareness of the structural violence of the broader Israeli-Palestinian struggle. In response, PAI students withdraw both physically and mentally from their campuses and concurrently mobilise within their communities to address unmet needs neglected by official authorities. The perceptions of PAI students regarding their institutions’ responses to political issues are marked by intense cynicism—a sentiment that is mitigated by individual supportive initiatives by faculty members. Based on the findings, the paper argues that periods of political escalation are not to be viewed as fleeting events that heighten emotions but rather as critical junctures where identities and perceptions are formed, leaving an impact that lasts long after the immediate turbulence subsides.

Interoception primes negative emotion processing during cognitive reappraisal: Electroencephalographical evidence

Interoception, which refers to sensing, interpreting, and integrating internal bodily signals, has been suggested to be associated with emotion regulation. Previous research has demonstrated individual differences in interoception and its impact on emotion regulation. However, the priming effect of interoception on emotion regulation and the underlying neural mechanisms remain unknown. This study aims to examine how interoception primes different strategies of cognitive reappraisal, using electroencephalography (EEG). Thirty-seven healthy participants completed an interoceptive priming task. We found that interoception increased the amplitudes of the late positive potential (LPP) during both interpretation and detachment strategies. The priming effect of interoception in enhancing LPP amplitudes lasted longer for interpretation than for detachment. A decrease in alpha power during reinterpretation was observed after interoceptive priming, but not during detachment. The results revealed that interoception enhanced attention to bodily signals associated with negative emotions during cognitive reappraisal. Interoception showed distinct effects on different strategies of cognitive reappraisal, with different underlying neural mechanisms. Interoception-based programs may be an effective way to enhance the capacity for cognitive reappraisal.

Young Adults’ Perceptions of Adverse Childhood Experiences as Context and Causes of Mental Health Conditions: Observations from the United States

BackgroundThe relationship between adverse childhood experiences (ACEs) and mental health later in life has been well-established. However, first-person qualitative narratives describing how ACEs negatively impact mental health of young adults are rare. ObjectiveQualitative data explores how young adults with serious mental health conditions (SMHC) describe childhood adversities and relate those experiences to their mental health conditions. Participants and SettingYoung adult participants (n=55; ages 25-30) who self-reported being diagnosed with an SMHC were recruited from one state in United States. In-person interviews were conducted to gather narratives related to mental health, education, training, and employment. MethodsYoung adults with lived experience actively participated in the research process. Iterative coding and thematic analysis were employed to assess ACEs reported and analyze how participants described those experiences as influential. ResultsMost participants identified as White, non-Hispanic women. Major depression and anxiety disorders were the most prevalent diagnoses. Over 80% reported experiencing trauma, familial mental illness, or substance use challenges. Young adults connected their ACEs to fear and anxiety, emotional processing difficulties, poor coping behaviors, delayed help-seeking, and later negative interpersonal relationships. ConclusionsThis study is the first to qualitatively describe how young adults with SMHC describe ACEs and relate those experiences to their own mental health conditions. Future research should seek similar first-hand accounts in vulnerable populations and consider the unique impact of the COVID-19 pandemic. Findings and future research can inform policy, practice, and mental health treatment for young adults who have experienced ACEs, especially in the post-pandemic era.

Emotional Dissonance and Coping Strategies According to the Emotional Processing Type of Call Center Counselors

Background: This study explored the emotional processing types of call center counselors and examined the differences in emotional dissonance and related adaptation indicates of coping strategies, emotional exhaustion and work performance orientation according to the types.Methods: A total of 271 call center agents (204 females, 67 males; mean age 36.5) participated in the study. Latent class analysis of emotional awareness, emotional expression, ambivalence over emotional expression were conducted. Analysis of variance(ANOVA) was used to examine differences in adaptation indicators according to emotion processing type.Results: Emotional processing types were categorized into Clear(CG), Passive(PG) Repressive(RG) groups. The CG showed low emotional dissonance, good adaptation indicates and functional coping strategies whereas results for the RG type revealed the opposite.Conclusions: By distinguishing between emotional processing types, this study found that emotional processing type is more closely correlated with burnout and work performance orientation than emotional dissonance itself.

Third, we detail TELL's speech-based assessments, each combining strategic tasks and features capturing diagnostically relevant domains (motor function, semantic memory, episodic memory, and emotional processing). Fourth, we specify the app's new data analysis, visualization, and download options. Finally, we list core challenges and opportunities for development. Overall, TELL v.2.0 offers scalable, objective, and multidimensional insights for the field. Through its technical and scientific breakthroughs, this tool can enhance disease detection, phenotyping, and monitoring.

"Hot" affect-related aspects in emotional information processing: The role of facial muscle responses in the direct and indirect processing of emotion categories.

The present study investigated the involvement of facial muscle responses in the indirect and direct processing of emotional facial expressions. Five discrete emotion categories were used, and we assessed both facial muscle and behavioral responses on a trial-by-trial basis. Experiment 1 tested facial muscle activation of clearly visible stimuli in an emotion categorization task. We observed emotion-specific facial muscle responses and corresponding behavioral categorization effects, providing evidence for the specificity of facial muscle activation. By contrast, under masked indirect presentation conditions in which emotional facial expressions were presented as primes in an emotion misattribution procedure, a specific pattern of emotion-congruent and cross-category behavioral misattributions was observed (in line with Rohr et al., 2015, 2018). Multilevel analyses in Study 2 suggest that an emotional reaction feeds into the behavioral decision, as indicated by differential activation of the frontalis lateralis in response to angry faces. Thus, the present study provides evidence that facial muscle responses contribute to behavioral decisions under masked indirect processing conditions. The different pattern of effects in both studies suggests that facial muscle responses index different processes, depending on the processing conditions: sensorimotor simulation in direct processing conditions and emotional reactions in masked indirect processing conditions. We discuss the implications for models that aim to account for facial muscle activity in response to emotional facial expressions. (PsycInfo Database Record (c) 2024 APA, all rights reserved).

인공지능 로봇의 도덕감정 함양 가능성에 대한 검토 -초등 도덕과를 중심으로-

This study examined the possibility of cultivating moral emotions of artificial intelligence robots that are developing recently. The 2022 revised elementary moral curriculum provides an opportunity for thought by asking questions about the relationship between artificial intelligence robots and humans. For the study, we first investigated the nature and expression process of emotions from ancient Western philosophy to modern brain science and neuroscience. Based on this, we explored what kind of emotional view the currently developed artificial intelligence robots express emotions based on. As a result, current artificial intelligence robots showed responses to humans using information accumulated through facial movements and facial expressions, focusing on basic emotions, according to Ekman's theory. This may be seen as a passive form based on human physical characteristics. However, moral emotion has a complex and active character that combines understanding of moral problem situations, empathy for others, and appropriate responses to situations. Accordingly, it was recommended to clearly teach the status and limitations of artificial intelligence robots in the field of current moral emotions in elementary moral education and educate students to form desirable relationships with artificial intelligence robots.

The impact of stimulus format and presentation order on social working memory updating.

Emotional faces and words have been extensively employed to examine cognitive emotional processing including social working memory, which plays a pivotal role in social interactions. However, it remains unclear which exact role these two stimulus formats play in updating specific emotional content, such as positive or negative information. Therefore, the current study examined the differences in working memory updating (WMU) of negative, neutral, and positive faces (Experiment 1) and words (Experiment 2), using a classic two-back paradigm with an event-related potential technique. In both experiments, emotional stimuli were presented in the same or different-valence order to further determine whether presentation order can also influence the WMU of specific emotional content. Our results showed that both stimulus format and presentation order play a role: (a) while faces showed an affective bias [larger P2 and late positive potential (LPP) for negative and positive faces than for neutral faces], words showed a negativity bias (larger LPP for negative words than both neutral and positive words); (b) While faces showed better performance with same-valence order, words showed better performance with different-valence order. Taken together, our findings indicate that, even if faces and words can contain the same emotional information, they impact social WMU differently.

TRPC4/5 inhibitors: Phase I results and proof of concept studies.

Transient receptor potential canonical (TRPC) ion channels are expressed in areas of the brain responsible for processing emotion and mood and have been implicated in the pathophysiology of internalizing disorders such as major depressive disorder and anxiety disorders. This review outlines the rationale for targeting TRPC ion channels for drug development, with specific focus on TRPC4 and TRPC5. We provide preclinical evidence that the lack of TRPC4 and TRPC5 channels or its pharmacological inhibition attenuate fear and anxiety without impairing other behaviors in mice. We also report on clinical studies of BI 1358894, a small molecule inhibitor of TRPC4/5 ion channels, demonstrating reduced psychological and physiological responses to induced anxiety/panic-like symptoms in healthy volunteers. Furthermore, we highlight an imaging study that investigated the acute effects of BI 1358894 and showed reduced activation in several brain regions involved in emotional processing. We conclude that these findings demonstrate a critical role for TRPC4 and TRPC5 in emotional processing, even though it remains an open question if the biological signatures of TRPC4/5 inhibition reported here translate into clinical efficacy and indicate that a TRPC4/5 inhibitor might provide a more effective treatment of internalizing disorders.

Neural Signature and Decoding of Unmanned Aerial Vehicle Operators in Emergency Scenarios Using Electroencephalography.

Brain-computer interface (BCI) offers a novel means of communication and control for individuals with disabilities and can also enhance the interactions between humans and machines for the broader population. This paper explores the brain neural signatures of unmanned aerial vehicle (UAV) operators in emergencies and develops an operator's electroencephalography (EEG) signals-based detection method for UAV emergencies. We found regularity characteristics similar to classic event-related potential (ERP) components like visual mismatch negativity (vMMN) and contingent negative variation (CNV). Source analysis revealed a sequential activation of the occipital, temporal, and frontal lobes following the onset of emergencies, corresponding to the processing of attention, emotion, and motor intention triggered by visual stimuli. Furthermore, an online detection system was implemented and tested. Experimental results showed that the system achieved an average accuracy of over 88% in detecting emergencies with a detection latency of 431.95 ms from the emergency onset. This work lays a foundation for understanding the brain activities of operators in emergencies and developing an EEG-based detection method for emergencies to assist UAV operations.

REM sleep and mental disorders on the 70th anniversary of the discovery of REM sleep.

The discovery of rapid eye movement sleep in 1953 led to numerous studies investigating the relationship between rapid eye movement sleep abnormalities and psychiatric disorders. The most salient findings were the association of rapid eye movement sleep alterations-reduced rapid eye movement sleep latency, increased rapid eye movement sleep volume of total sleep, and increased rapid eye movement density-with major depression. This paper briefly reviews the history of rapid eye movement sleep research in psychiatry with a focus on the work related to major depressive disorder and some of the various theories that have been proposed to explain the associated rapid eye movement sleep abnormalities. Given the increasing evidence that rapid eye movement sleep is important for emotional processing, memory and cognition, a better understanding of the underlying mechanisms for the relationship between rapid eye movement sleep and mood disorders could lead to improved treatments for these common and disabling illnesses.
