Unveiling the neural dynamics of conscious perception in rapid object recognition

Our brain excels at recognizing objects, even when they flash by in a rapid sequence. However, the neural processes determining whether a target image in a rapid sequence can be recognized or not remains elusive. We used electroencephalography (EEG) to investigate the temporal dynamics of brain processes that shape perceptual outcomes in these challenging viewing conditions. Using naturalistic images and advanced multivariate pattern analysis (MVPA) techniques, we probed the brain dynamics governing conscious object recognition. Our results show that although initially similar, the processes for when an object can or cannot be recognized diverge around 180 ms post-appearance, coinciding with feedback neural processes. Decoding analyses indicate that gist perception (partial conscious perception) can occur at ∼120 ms through feedforward mechanisms. In contrast, object identification (full conscious perception of the image) is resolved at ∼190 ms after target onset, suggesting involvement of recurrent processing. These findings underscore the importance of recurrent neural connections in object recognition and awareness in rapid visual presentations.

Inattentional aftereffects: The role of attention on the strength of the motion aftereffect.

The way that attention affects the processing of visual information is one of the most intriguing fields in the study of visual perception. One way to examine this interaction is by studying the way perceptual aftereffects are modulated by attention. In the present study, we have manipulated attention during adaptation to translational motion generated by coherently moving random dots, in order to investigate the effect of the distraction of attention on the strength of the peripheral dynamic motion aftereffect (MAE). A foveal rapid serial visual presentation task (RSVP) of varying difficulty was introduced during the adaptation period while the adaptation and test stimuli were presented peripherally. Furthermore, to examine the interaction between the physical characteristics of the stimulus and attention, we have manipulated the motion coherence level of the adaptation stimuli. Our results suggested that the removal of attention through an irrelevant task modulated the MAE's magnitude moderately and that such an effect depends on the stimulus strength. We also showed that the MAE still persists with subthreshold and unattended stimuli, suggesting that perhaps attention is not required for the complete development of the MAE.

Analysis of Technological Development and Enhancement in Modern Film Noir

This paper explores the visual and technological evolution of film noir, particularly the transition from classic to modern film noir. Originally defined by French film critics, film noir is known for its distinctive low-key lighting and strong visual contrasts, emphasizing a mysterious and dramatic visual presentation. The article first compares low-key lighting in traditional and modern film noir, highlighting modern advancements in controlling lighting and shadows. It then examines color usage in both eras, noting modern noir’s use of low saturation and vivid colors for enhanced emotional impact. Lastly, it explores modern technology’s role in restoring classic film noir, emphasizing high-resolution scanning and digital processing for improved visual and auditory quality while preserving artistic style. These analyses underscore film noir’s adaptation to technological advancements in global cinema. Through these analyses, the paper reveals how film noir has adapted to technological advancements to maintain its significant place in global cinematic art. Nonetheless, it acknowledges limitations, primarily focusing on visual and technological aspects while neglecting potential socio-cultural, political, and economic influences on the genre. Future research could address these gaps by exploring interdisciplinary perspectives and incorporating quantitative methods to provide a more comprehensive understanding of film noir’s evolution.

The toxicity swimmer plot: A novel approach for evaluating patient-level toxicity following immune checkpoint inhibitor (ICI) therapy on the Checkmate 214 trial.

11014 Background: Treatment with ICIs creates the possibility of prolonged disease control or remission but also creates the possibility of prolonged toxicity even after treatment is discontinued. Treatment-free survival (TFS) with and without toxicity has previously been described as an integral piece of a partitioned survival analysis in advanced renal cell carcinoma (aRCC). Prior analyses have reported further partition of TFS as mean duration of TFS with and without treatment-related adverse events (TRAEs), but this metric fails to provide more granular information regarding individual patients experiencing toxicity during TFS. We present a novel extended swimmer plot that characterizes patient-level toxicity data within TFS using the example of the Checkmate 214 trial to complement analyses of the population average experience. Methods: Data were analyzed from the Checkmate 214 trial which randomized 1096 patients with aRCC to receive either first-line (1L) nivolumab plus ipilimumab (n = 550) or sunitinib (n = 546). The minimum follow-up from protocol therapy initiation was 42 months. Patients’ overall survival was partitioned into 3 survival states: time on 1L protocol therapy, TFS, and survival after subsequent therapy initiation. With a re-defined time origin relative to cessation of 1L protocol therapy, we generated swimmer plots highlighting the TFS period and documenting each patient’s experience with and without grade 2+ and grade 3+ TRAEs during TFS. The swimmer plot was sorted by duration of TFS and duration of TFS with grade 2+ TRAEs in order to illustrate patterns of individuals’ experiences. Results: The 42-month mean TFS was 7.8 months (with grade 2+ TRAEs: 3.2 months) for patients treated with nivolumab plus ipilimumab and 3.3 months (1.6 months) for patients treated with sunitinib. In the respective treatment groups, TFS with grade 2+ TRAEs was experienced by 32% and 25% of patients and comprised of 13% and 9% of patients for whom it was the entire TFS period. These percentages were consistent regardless of TFS duration. TFS with grade 3+ TRAEs was experienced by 15% and 3% of patients, respectively. For most patients having TFS with TRAEs, the TRAEs persisted from the protocol therapy period, but 7% and 1% of patients in the respective treatment groups had new-onset grade 3+ TRAE during TFS. A swimmer plot will be presented as a visual presentation of this study’s results. Conclusions: We describe a novel extension of swimmer plots for presenting patient-level information and illustrating patterns in toxicity duration relative to TFS by incorporating individual toxicity data into a swimmer plot of partitioned survival. This approach allows for a more comprehensive understanding of toxicity trends and risk of prolonged toxicity after treatment is discontinued.

Determinants of choice of media content in internet space among Russian youth (based on independent sociological survey)

In this article, the authors conducted a sociological study among Russian youth to determine the factors that influence the choice of media content. The sample was 610 respondents aged 14–35. The urgency of the work is presented by the need to find out the reasons that form the media studies of Russian youth, in order to develop effective tools and solutions to increase the level of digital literacy of the modern generation. Respondents were asked questions that helped the authors to find out which platforms they preferred to obtain information, which format and type of content they preferred, and what the interviewees pay attention to when choosing the source of information, the reliability and reliability of the information. The results of the study showed that young people demonstrate a high level of interaction with the Internet space and all types of content, from entertainment to education, preferring text and visual presentation of information. For the younger generation in Russia, it is no longer important to have an official media license to choose a source of information, they are not sufficiently aware of methods to establish the reliability and reliability of the information received. It is more important for audiences between the ages of 14–35 to be popular and responsive to their interests and needs. The authors in this article conclude that in the media environment young people should have a request to improve digital skills, such as critical assessment of online content, cyber security awareness and responsible digital citizenship.

Bibliometric and Visualization Analysis of Research Hotspots and Frontiers in Endoscopic Lumbar Discectomy.

The increasing utilization of endoscopic lumbar discectomy (ELD) in spinal surgery has sparked widespread interest and research. This study utilizes bibliometric analysis to identify current research trends and advancements in this innovative surgical technique, with the goal of informing and improving surgical practices. We retrieved relevant literature on ELD from the Science Citation Index Expanded (SCI-Expanded) within the Web of Science Core Collection (WoSCC) database as research samples. Various visualization tools, such as VOSviewer, CiteSpace, Scimago Graphica, Pajek, and online bibliometric platform, were employed to generate scientific knowledge maps for the purpose of visual presentation and data analysis. Over the past two decades, there has been significant progress in the research related to ELD, particularly since 2016. China has emerged as the most productive country, while South Korea and the United States have exerted greater academic influence. Tongji University has contributed the highest number of research output, while academic achievements published by Wooridul Spine Hospital are highly esteemed by scholars. Lee SH and Ruetten S are the most prolific author and the most highly cited author, respectively. World Neurosurg has published the highest number of publications, while Spine has become the most influential journal. Clinical Neurology and Surgery are the primary subject categories. Research in this field primarily revolves around improving ELD techniques, evaluating postoperative efficacy and prognosis prediction, studying complications and risk factors, as well as comparative research with other surgical techniques. Keywords such as risk factors, LDH, PETD, lumbar spinal stenosis, degeneration, recurrent herniation, laminectomy, local anesthesia, and foraminoplasty highlight the current research hotspots and future cutting-edge trends. This study employed bibliometric analysis to elucidate the research hotspots and frontiers in ELD. The findings have significant implications for advancing research and development in this field.

Rapid Serial Visual Presentation of transposed-word sequences in the grammatical decision task: an examination of the roles of temporal and spatial cues to word order

ABSTRACT Transposing two words in a sentence (e.g. “cat” and “was” in “the white cat was big”) creates a sequence that is harder to classify as ungrammatical than control sequences (e.g. “the white was cat slowly”), suggesting that word position coding is noisy and can be affected by syntactic expectations. In the present research, this transposed-word effect was examined more closely using Rapid Serial Visual Presentation (RSVP) formats which provided either clear temporal cues to word order but no spatial cues, or both types of cues. Compared to when all words were presented simultaneously, the two RSVP formats reduced the transposed-word effect to the same degree while having no parallel impact on another ungrammatical comparison condition involving no transposition. These results are discussed in the context of serial and parallel models of reading as well as models that propose a later processing stage for the locus of the transposed-word effect.

A user-friendly visual brain-computer interface based on high-frequency steady-state visual evoked fields recorded by OPM-MEG

Objective. Magnetoencephalography (MEG) shares a comparable time resolution with electroencephalography. However, MEG excels in spatial resolution, enabling it to capture even the subtlest and weakest brain signals for brain-computer interfaces (BCIs). Leveraging MEG’s capabilities, specifically with optically pumped magnetometers (OPM-MEG), proves to be a promising avenue for advancing MEG-BCIs, owing to its exceptional sensitivity and portability. This study harnesses the power of high-frequency steady-state visual evoked fields (SSVEFs) to build an MEG-BCI system that is flickering-imperceptible, user-friendly, and highly accurate. Approach. We have constructed a nine-command BCI that operates on high-frequency SSVEF (58–62 Hz with a 0.5 Hz interval) stimulation. We achieved this by placing the light source inside and outside the magnetic shielding room, ensuring compliance with non-magnetic and visual stimulus presentation requirements. Five participants took part in offline experiments, during which we collected six-channel multi-dimensional MEG signals along both the vertical (Z-axis) and tangential (Y-axis) components. Our approach leveraged the ensemble task-related component analysis algorithm for SSVEF identification and system performance evaluation. Main Results. The offline average accuracy of our proposed system reached an impressive 92.98% when considering multi-dimensional conjoint analysis using data from both the Z and Y axes. Our method achieved a theoretical average information transfer rate (ITR) of 58.36 bits min−1 with a data length of 0.7 s, and the highest individual ITR reached an impressive 63.75 bits min−1. Significance. This study marks the first exploration of high-frequency SSVEF-BCI based on OPM-MEG. These results underscore the potential and feasibility of MEG in detecting subtle brain signals, offering both theoretical insights and practical value in advancing the development and application of MEG in BCI systems.

The Absence of Attentional Bias to Low-Calorie Food Stimuli in Restrictive Dieters: Differences in the Allocation of Attentional Resources to High-Calorie Foods.

Restrictive dieters are those who expect to achieve body shape and weight control through dieting. However, they often have difficulty suppressing the desire to consume food when confronted with it. It has been shown that when high- and low-calorie foods are presented together, the attention of restrictive eaters is preferentially directed to high-calorie foods. However, whether attentional bias occurs when low-calorie foods are present alone and whether the allocation of attentional resources is consistent with that for high-calorie foods has yet to be explored. The present study focused on the effects of high-/low-calorie foods on attentional bias in restrictive dieters. Seventy-eight participants were recruited to participate in the experiment via the Dutch Eating Behavior Questionnaire (DEBQ) scale, which is administered in a rapid serial visual presentation (RSVP) task. The results revealed that failed restrictive dieters had the lowest percentage of correct answers at the lag2 level, indicating attentional bias. Failed restrictive dieters allocated more attentional resources to high-calorie foods than to low-calorie foods. Restrictive dieters showed no attentional bias when low-calorie foods were presented alone. The results suggest that low-calorie foods do not elicit an attentional bias in restrictive dieters and that the allocation of attentional resources is not consistent when compared to that for high-calorie foods.

Enhancing rhythmic temporal expectations: The dominance of auditory modality under spatial uncertainty.

To effectively process the most relevant information, the brain anticipates the optimal timing for allocating attentional resources. Behavior can be optimized by automatically aligning attention with external rhythmic structures, whether visual or auditory. Although the auditory modality is known for its efficacy in representing temporal information, the current body of research has not conclusively determined whether visual or auditory rhythmic presentations have a definitive advantage in entraining temporal attention. The present study directly examined the effects of auditory and visual rhythmic cues on the discrimination of visual targets in Experiment 1 and on auditory targets in Experiment 2. Additionally, the role of endogenous spatial attention was also considered. When and where the target was the most likely to occur were cued by unimodal (visual or auditory) and bimodal (audiovisual) signals. A sequence of salient events was employed to elicit rhythm-based temporal expectations and a symbolic predictive cue served to orient spatial attention. The results suggest a superiority of auditory over visual rhythms, irrespective of spatial attention, whether the spatial cue and rhythm converge or not (unimodal or bimodal), and regardless of the target modality (visual or auditory). These findings are discussed in terms of a modality-specific rhythmic orienting, while considering a single, supramodal system operating in a top-down manner for endogenous spatial attention.

Evaluation of Different Types of Stimuli in an Event-Related Potential-Based Brain-Computer Interface Speller under Rapid Serial Visual Presentation.

Rapid serial visual presentation (RSVP) is currently a suitable gaze-independent paradigm for controlling visual brain-computer interfaces (BCIs) based on event-related potentials (ERPs), especially for users with limited eye movement control. However, unlike gaze-dependent paradigms, gaze-independent ones have received less attention concerning the specific choice of visual stimuli that are used. In gaze-dependent BCIs, images of faces-particularly those tinted red-have been shown to be effective stimuli. This study aims to evaluate whether the colour of faces used as visual stimuli influences ERP-BCI performance under RSVP. Fifteen participants tested four conditions that varied only in the visual stimulus used: grey letters (GL), red famous faces with letters (RFF), green famous faces with letters (GFF), and blue famous faces with letters (BFF). The results indicated significant accuracy differences only between the GL and GFF conditions, unlike prior gaze-dependent studies. Additionally, GL achieved higher comfort ratings compared with other face-related conditions. This study highlights that the choice of stimulus type impacts both performance and user comfort, suggesting implications for future ERP-BCI designs for users requiring gaze-independent systems.

The Interweaving of Film Media and Cultural Inheritance: A Case Study of Chang An

The explosion of the new cultural animated film series Chang An has opened a new prelude to the interweaving of traditional culture and modern media, and has become a new focus of research on cultural heritage. With the advent and challenges of the new media era, Chang An, as a film that presents the profound heritage of Chinese culture, cleverly uses unique narrative techniques and visual presentation. Based on the focus of telling good Chinese stories, modern media plays a powerful role in communication, driving the prosperity and development of the cultural industry. This paper aims to explore the communication strategies and effects of film media on cultural heritage. By using content analysis method to analyze the film Chang An in detail, it strives to reveal how the film not only inherits Chinese culture but also successfully attracts the attention of modern audiences. The research results show that the communication effect of the film is very significant, realizing creative communication and cross-cultural dialogue, improving the audience's identity with traditional culture, and showing the potential and value of film media in cultural heritage.

A metric for comparison and visualization of age disparities in cancer survival

AimsDiagnostic age is an important determinant of cancer survival but the methods generally used to analyze age-group-specific survival are not developed for ready visualization of survival differences. We aim at developing a novel metric for comparing and visualizing age-group-specific survival data over different cancers, sexes, periods and countries. MethodsThe metric describes the mean absolute deviation between age-groups. The metric can be used in two variations, one showing the mean variation and its 95% confidence intervals and the other highlighting individually each age-groups distinguishing positive or negative deviations. We demonstrate the applications with age-group- specific 5-year relative survival data from the NORDCAN database ResultsThe mean absolute deviation between age-groups for Swedish colon cancer survival declined from about 5% in 1972–1981–1% in 1992–2001 and to 1.3% in 2012–2021. Patients diagnosed before age 50 years accounted for the largest positive deviation. For acute myeloid leukemia (AML) the mean deviation increased from 4% (female) to 17% and 23%. Patients diagnosed at age below 50 years showed the largest deviations. Comparing colon cancer mean deviations between the Nordic countries, a time-related decline was observed for all, those in Sweden ending at the lowest and in Finland the highest level. ConclusionsWe demonstrated the usefulness of the devised metric for summarizing age-specific survival data between cancers, sexes, periods and countries. The two variations of the metric allow a simple visual presentation of the survival experience as to deviation of the survival data, its 95%CIs and its highlighted individual age-group components.

Semantic image sorting method for RSVP presentation

Objective. The rapid serial visual presentation (RSVP) paradigm, which is based on the electroencephalogram (EEG) technology, is an effective approach for object detection. It aims to detect the event-related potentials (ERP) components evoked by target images for rapid identification. However, the object detection performance within this paradigm is affected by the visual disparity between adjacent images in a sequence. Currently, there is no objective metric to quantify this visual difference. Consequently, a reliable image sorting method is required to ensure the generation of a smooth sequence for effective presentation. Approach. In this paper, we propose a novel semantic image sorting method for sorting RSVP sequences, which aims at generating sequences that are perceptually smoother in terms of the human visual experience. Main results. We conducted a comparative analysis between our method and two existing methods for generating RSVP sequences using both qualitative and quantitative assessments. A qualitative evaluation revealed that the sequences generated by our method were smoother in subjective vision and were more effective in evoking stronger ERP components than those generated by the other two methods. Quantitatively, our method generated semantically smoother sequences than the other two methods. Furthermore, we employed four advanced approaches to classify single-trial EEG signals evoked by each of the three methods. The classification results of the EEG signals evoked by our method were superior to those of the other two methods. Significance. In summary, the results indicate that the proposed method can significantly enhance the object detection performance in RSVP-based sequences.

Exploring the consent process among pregnant and breastfeeding women taking part in a maternal vaccine clinical trial in Kampala, Uganda: a qualitative study

BackgroundThe involvement of pregnant women in vaccine clinical trials presents unique challenges for the informed consent process. We explored the expectations and experiences of the pregnant women, spouses/partners, health workers and stakeholders of the consent process during a Group B Streptococcus maternal vaccine trial.MethodsWe interviewed 56 participants including pregnant women taking part in the trial, women not in the trial, health workers handling the trial procedures, spouses, and community stakeholders. We conducted 13 in-depth interviews and focus group discussions with 23 women in the trial, in-depth interviews with 5 spouses, and 5 women not in the trial, key informant interviews with 5 health workers and 5 other stakeholders were undertaken.ResultsDecision-making by a pregnant woman to join a trial was done in consultation with spouse, parents, siblings, or trusted health workers. Written study information was appreciated by all but they suggested the use of audio and visual presentation to enhance understanding. Women stressed the need to ensure that their male partners received study information before their pregnant partners joined a clinical trial. Confidentiality in research was emphasised differently by individual participants; while some emphasised it for self, others were keen to protect their family members from being exposed, for allowing them to be involved in research. However, others wanted their community participation to be acknowledged.ConclusionWe found that pregnant women make decisions to join a clinical trial after consulting with close family. Our findings suggest the need for an information strategy which informs not only the pregnant woman, but also her family about the research she is invited to engage in.
