Depression significantly affects interpersonal functioning.Social avoidance may play an important role in depression, limiting opportunities and social skills acquisition, contributing to the maintenance of difficulties.In last few years, need for studying interactions using interactive tasks has been highlighted.This study investigated unmedicated depressed (n ϭ 26) matched healthy control participants, a novel computerized decision-making task (the TEAM task).In this task, participants...
The study of associations between inter-individual differences in brain structure and behaviour has a long history psychology neuroscience. Many psychometric data, particularly intelligence personality measures local variations have been reported. While the impact such reported often goes beyond scientific communities, resonating public mind, their replicability is rarely evidenced. Previously, we shown that estimates grey matter volume (GMV) result replicated findings across large samples...
Abstract Depression and social anxiety are common disorders that have a profound impact on functioning. The need for studying the neural substrates of interactions in mental using interactive tasks has been emphasized. field neuroeconomics, which combines neuroscience techniques behavioral economics multiplayer such as Ultimatum Game (UG), can contribute this direction. We assessed emotions, behavior, Event‐Related Potentials participants with depression and/or symptoms (MD/SA, n = 63, 57...
Abstract Identifying associations between interindividual variability in brain structure and behaviour requires large cohorts, multivariate methods, out-of-sample validation and, ideally, out-of-cohort replication. Moreover, the influence of nature vs nurture on brain-behaviour should be analysed. We analysed (grey matter volume, cortical thickness, surface area) (spanning cognition, emotion, alertness) using regularized canonical correlation analysis a machine learning framework that tests...
Abstract The human hippocampus is a key region in cognitive and emotional processing, but also vulnerable plastic region. Accordingly, there great interest understanding how variability hippocampus’ structure relates to behavior healthy clinical populations. In this study, we aimed link interindividual subregional hippocampal networks (i.e. the brain grey matter of subregions) behavioral phenotype. To do so, used multi-block multivariate approach mapping association between volume...
Motor performance (MP) is essential for functional independence and well-being, particularly in later life. However, the relationship between behavioural aspects such as sleep quality depressive symptoms, which contribute to MP, underlying structural brain substrates of their interplay remains unclear. This study used three population-based cohorts younger older adults (n=1,950) from Human Connectome Project-Young Adult (HCP-YA), HCP-Aging (HCP-A), enhanced Nathan Kline Institute-Rockland...
Abstract Social comparison is central in human life and can be especially challenging depression social anxiety. We assessed event‐related potentials emotions using a task which participants received feedback on both their own co‐player's performance, with and/or anxiety ( n = 63) healthy controls 72). Participants reported more negative for downward (being better than the co‐player [participant correct, wrong]) upward worse wrong, correct]) comparisons versus even outcomes, these effects...
Prepartum depression is associated with early adversity, pregnancy complications, preterm delivery, postpartum depression, and long-term effects on child neurodevelopment. The oxytocin (OXT) system affected by adverse experiences has been depression. In the current study, we investigated risk factors for prenatal depressive symptoms, mainly of childhood adolescence trauma, in combination presence certain variants polymorphisms OXT receptor (OXTR) genes. We hypothesized that trauma higher...
Machine learning (ML) provides powerful tools for predictive modeling. ML's popularity stems from the promise of sample-level prediction with applications across a variety fields physics and marketing to healthcare. However, if not properly implemented evaluated, ML pipelines may contain leakage typically resulting in overoptimistic performance estimates failure generalize new data. This can have severe negative financial societal implications. Our aim is expand understanding associated...
The iterated prisoner’s dilemma (iPD) game is a well-established model for testing how people cooperate, and the neural processes that unfold after its distinct outcomes have been partly described. Recent theoretical models suggest evolution favors intuitive cooperation, which raises questions on behavioral but also timelines involved. We studied outcome/feedback stage of iPD rounds with electroencephalography (EEG) methods. Results showed signals associated this relate to future choice, in...
OHBM Brainhack 2022 took place in June 2022. The first hybrid hackathon, it had an in-person component taking Glasgow and three hubs around the globe to improve inclusivity fit as many timezones possible. In buzzing setting of Queen Margaret Union virtual platform, 23 projects were presented after development. Following are reports 14 those, well a recapitulation organisation event.
Summary There is a recognized link between risk factors for non-communicable diseases and brain health. However, the specific effects that they have on health are still poorly understood, preventing its implementation in clinical practice. For instance, association such cortical thickness (CT) has been primarily explored using univariate/bivariate methods global/lobar measures of CT yielded inconsistent results. In this work, we aim to study relationship CT. addition, adopt systems-level...

We assessed event-related potentials emotions when receiving feedback on both their own a co-player’s performance, participants with and/or anxiety (n=63) healthy controls (n=72).

Abstract Electing whether to cooperate with someone else is well typified in the iterated prisoner’s dilemma (iPD) game, although neural processes that unfold after its distinct outcomes have been only partly described. Recent theoretical models emphasize ubiquity of intuitive cooperation, raising questions on timelines involved. We studied outcome stage an iPD electroencephalography (EEG) methods. Results showed signals are modulated by can also be indicative future choice,...
