Recursive social decision-making requires the use of flexible, context-sensitive long-term strategies for negotiation. To succeed in bargaining, participants' own perspectives must be dynamically integrated with those interactors to maximize self-benefits and adapt other's preferences, respectively. This is a prerequisite develop successful self-other integration strategy. While such form strategic interaction critical decision-making, little known about its neurocognitive correlates. bridge...
Social cognition consists of several skills which allow us to interact with other humans. These include social stimuli processing, drawing inferences about others' mental states, and engaging in interactions. In recent years, there has been growing evidence cognitive impairments patients schizophrenia. Apparently, these are separable from general neurocognitive impairments, such as attention, memory executive functioning. Moreover, seems be a main determinant functional outcome could used...
Abstract Whether maximizing rewards and minimizing punishments rely on distinct brain systems remains debated, given inconsistent results coming from human neuroimaging animal electrophysiology studies. Bridging the gap across techniques, we recorded intracerebral activity twenty participants while they performed an instrumental learning task. We found that both reward punishment prediction errors (PE), estimated computational modeling of choice behavior, correlate positively with broadband...
Humans often face the challenge of making decisions between ambiguous options. The level ambiguity in decision-making has been linked to activity parietal cortex, but its exact computational role remains elusive. To test hypothesis that cortex plays a causal computing probabilities, we conducted consecutive fMRI and TMS-EEG studies. We found participants assigned unknown probabilities objective elevating uncertainty their decisions. Parietal correlated with degree process underestimates...
Patients recovering from COVID-19 commonly exhibit cognitive and brain alterations, yet the specific neuropathological mechanisms risk factors underlying these alterations remain elusive. Given significant global incidence of COVID-19, identifying that can distinguish individuals at developing is crucial for prioritizing follow-up care. Here, we report findings a sample patients consisting 73 adults with mild to moderate SARS-CoV-2 infection without signs respiratory failure 27 infections...
In social interactions, the perception of how risky our decisions are depends on we anticipate other people's behaviors. We used electroencephalography to study neurobiology risk, in subjects playing role proposers an iterated ultimatum game pairs. Based statistical modeling, previous behaviors both players separate high-risk [HR] offers from low-risk [LR] offers. The HR present higher rejection probability and entropy (variability possible outcome) than LR Rejections elicited a stronger...
Abstract A dysfunction in the excitatory–inhibitory (E/I) coordination neuronal assembly has been proposed as a possible neurobiological mechanism of Autistic Spectrum Disorder (ASD). However, potential impact this cognitive performance is not fully explored. Since main consequence E/I an impairment oscillatory activity and its underlying computations, we assessed electroencephalographic ASD typically developing (TD) subjects during working-memory task. We found that committed more errors...
During social bargain, one has to both figure out the others’ intentions and behave strategically in such a way that behaviors will be consistent with one’s expectations. To understand neurobiological mechanisms underlying these behaviors, we used electroencephalography while subjects played as proposers repeated ultimatum game. We found adapted their offers obtain more acceptances last round this adaptation correlated negatively prefrontal theta oscillations. People higher activity related...
Abstract Attentional mechanisms have been studied mostly in specific sensory domains, such as auditory, visuospatial, or tactile modalities. In contrast, attention to internal interoceptive visceral targets has only recently begun be studied, despite its potential importance emotion, empathy, and self‐awareness. Here, we the effects of shifting heart using a cue‐target detection paradigm during continuous EEG recordings. Subjects were instructed count either series visual stimuli (visual...
Adaptive behavior requires the comparison of outcome predictions with actual outcomes (e.g., performance feedback). This process monitoring is computed by a distributed brain network comprising medial prefrontal cortex (mPFC) and anterior insular (AIC). Despite being consistently co-activated during different tasks, precise neuronal computations each region their interactions remain elusive. In order to assess neural mechanism which AIC processes feedback, we recorded electrophysiological...
Abstract Social cognition refers to the brain mechanisms by which we process social information about other humans and ourselves. Alterations in interpersonal functioning are common major depressive disorder, though only poorly addressed current pharmacotherapies. Further standardized tests, such as depression ratings or neuropsychologic used routine practice provide very little on skills, schemas, attributions, stereotypes judgments related interactions. In this article, review recent...
Intra-individual variability of Response Times (RTisv) is considered as potential endophenotype for Attentional Deficit/Hyperactivity Disorder (ADHD). Traditional methods estimating RTisv lose information regarding (RTs) distribution along the task, with eventual effects on statistical power. Ex-Gaussian analysis captures dynamic nature RTisv, normal and exponential components RT distribution, specific phenomenological correlates. Here, we applied ex-Gaussian to explore whether...
Abstract Working Memory (WM) impairment is the most common cognitive deficit of patients with Multiple Sclerosis (MS). However, evidence its neurobiological mechanisms scarce. Here we recorded electroencephalographic activity twenty relapsing-remitting MS and minimal deficit, 20 healthy control (HC) subjects while they solved a WM task. In spite similar performance, HC group demonstrated both correlation between temporoparietal theta memory load, medial frontal successful performances. did...
Abstract Background The ageing population has increased the prevalence of disabling and high-cost diseases, such as dementia mild cognitive impairment (MCI). latter can be considered a prodromal phase some dementias critical stage for interventions to postpone functionality. Working memory (WM) is pivotal function, representing fundamental element executive functions. This project proposes an intervention protocol enhance WM in these users, combining training with transcranial electrical...
The capacity to inhibit prepotent and automatic responses is crucial for proper cognitive social development, inhibitory impairments have been considered be key some neuropsychiatric conditions. One of the most used paradigms analyze processes Go-Nogo task (GNG). This has widely in psychophysical EEG studies, more recently using fMRI. However, a technical limitation that time resolution fMRI poorer than technique. In order compensate these temporal constraints, it become common practice...
Introduction Decision-making is a process that can be strongly affected by social factors. Evidence has shown how people deviate from traditional rational-choice predictions under different levels of interactions. The emergence prosocial decision-making, defined as any action addressed to benefit another individual even at the expense personal benefits, been reported an example such influence. Furthermore, brain evidence involvement structures prefrontal cortex, anterior insula, and...
During childhood, schools are a crucial environment for social interactions, making them ideal forevaluating the inclusion of children with special educational needs (SEN). Children AutismSpectrum Disorder (ASD) often face challenges in peer relationships, yet how this condition impactsspecific dynamics and school coexistence is not well understood. To address issue, weexamined relationships within elementary schools. We hypothesized that,compared to their peers without ASD, ASD: (i) occupy...
Multiple sclerosis (MS) is a prevalent neurological disorder marked by inflammation and demyelination, with fatigue being one of the most reported debilitating symptoms. While occurs across various conditions even in healthy individuals, specific mechanisms contributing to each context remain unclear. In this study, we conducted cross-sectional analysis involving 32 people relapsing MS (PwRMS) 29 controls who fatigue. Participants underwent MRI scans, including T1-weighted diffusion-weighted...
