Abstract The feedback‐related negativity (FRN) has been hypothesized to be most sensitive unexpected negative feedback. present study investigated feedback expectancy and valence using a probabilistic gambling paradigm where subjects encountered expected or positive outcomes. In line with previous studies, FRN amplitude reflected reward prediction error, but minor extent also error. Moreover, the P300 was largest after feedback, irrespective of valence. We propose interpret in terms...
The anticipation of favourable or unfavourable events is a key component in our daily life. However, the temporal dynamics processes relation to brain activation are still not fully understood. A modified version monetary incentive delay task was administered during separate functional magnetic resonance imaging (fMRI) and electroencephalogram (EEG) sessions same 25 participants assess anticipatory with multi-modal neuroimaging set-up. During fMRI, gain loss were both associated heightened...
Abstract Objectives: Anticipatory processes prepare the organism for upcoming experiences. The aim of this study was to investigate neural responses related anticipation and processing painful stimuli occurring with different levels uncertainty. Experimental design: Twenty‐five participants (13 females) took part in an electroencephalography functional magnetic resonance imaging (fMRI) experiment at separate times. A visual cue announced occurrence electrical or nonpainful stimulus,...
Two event-related brain potential (ERP) components, the frontocentral feedback-related negativity (FRN) and posterior P300, are key in feedback processing. The FRN typically exhibits greater amplitude response to negative unexpected outcomes, whereas P300 is generally more pronounced for positive outcomes. In an influential ERP study, Hajcak et al., (2005) manipulated outcome valence expectancy a guessing task. They found was larger outcomes regardless of expectancy, valence. These findings...
Abstract Several previous functional magnetic resonance imaging (fMRI) studies have demonstrated the predictive value of brain activity during emotion processing for antidepressant response, with a focus on clinical outcome after 6–8 weeks. However, longitudinal emphasize paramount importance early symptom improvement course disease in major depressive disorder (MDD). We therefore aimed to assess whether neural discrimination task (EDT) predicts effects, and how these measures relate more...
Violent offending has often been associated with a lack of empathy, but experimental investigations are rare. The present study aimed at clarifying whether violent offenders show general empathy deficit or specific deficits regarding the separate subcomponents. To this end, we assessed three core components (emotion recognition, perspective taking, affective responsiveness) as well skin conductance response (SCR) in sample 30 male and healthy controls. Data analysis revealed reduced accuracy...
This study investigated affective and cognitive empathic processes in incarcerated violent offenders with lower higher psychopathic traits healthy controls. Participants witnessed painful expressions of others displayed on video clips. Skin conductance responses (SCR) were recorded to assess autonomic emotional arousal, various empathy ratings used as measures self-reported vicarious responses. Reduced SCRs occurred during the observation pain psychopathic-trait participants alike, compared...
Background/Objectives: Irritable bowel syndrome (IBS) is a gut-brain disorder characterized by abdominal pain, altered habits, and psychological distress. While brain-gut interactions are recognized in IBS pathophysiology, the relationship between brain morphometry, cognitive function, clinical features remains poorly understood. The study aims to conduct following: (i) replicate previous univariate morphometric findings patients software comparisons; (ii) investigate whether multivariate...
Recent years have provided increasing insights into the factors affecting economic decision-making. Little is known about how these influence decisions that also bear consequences for other people. We examined whether affected a third, passive player modulate behavioral and neural responses to monetary offers in modified version of three-person ultimatum game. aimed elucidate what extent social preferences affect early neuronal processing when subjects were evaluating fair or unfair...
Empathy for another person's pain and feeling oneself seem to be accompanied by similar or shared neural responses. Such responses could achieved mapping the bodily states of others onto our own representations. We investigated whether sensorimotor are increased when experimentally reducing perceived distinction between self other. Healthy adult participants watched video clips hands ethnic ingroup outgroup members being painfully penetrated a needle syringe touched cotton swab. Manipulating...
Purpose of the study: Work addiction risk is a growing public health concern with potential deleterious health-related outcomes. Perception work (job demands and job control) may play major role in provoking employees. We aimed to explore link between outcomes using framework job-demand-control model. Methods: Data were collected from 187 out 1580 (11.8%) French workers who agreed participate cross-sectional study WittyFit software online platform. The self-administered questionnaires Job...
The gut hormone ghrelin drives food motivation and increases intake, but it is also involved in the anticipation of response to rewards other than food. This pre-registered study investigated how naturally varying concentrations affect processing touch as a social reward humans. Sixty-seven volunteers received slow caressing (so-called CT-targeted touch) control on their shins during 3T functional imaging two test days. On one occasion, participants were fasted, another, they meal. each...
Abstract The current study investigated whether or not the physical aspect of stimulus size has an effect on neuronal correlates feedback processing. A time estimation task was administered applying three different categories: small, middle, and large stimuli. Apart from early visual ERPs such as P1 N1 components, later processing stages were also affected by In particular, small stimuli compared to middle ones led diminished amplitudes in both FRN P300 despite intact discrimination between...
Abstract Major depressive disorder (MDD) has been hypothesized to lead impairments in empathy. Previous cross-sectional studies did not disentangle effects of MDD itself and antidepressant treatment. In this first longitudinal neuroimaging study on empathy depression, 29 patients with participated two functional magnetic resonance imaging (fMRI) sessions before after 3 months therapy. We compared their responses an for pain task a group healthy controls ( N = 35). All participants provided...

Experiencing feelings of helplessness has repeatedly been reported to contribute depressive symptoms and negative affect. In turn, depression affective states are associated, among others, with impairments in performance monitoring. Thus, the question arises whether monitoring is also affected by helplessness. To this end, after induction via an unsolvable reasoning task, 37 participants (20 females) performed a modified version Flanker task. Based on previously validated questionnaire, 17...
Functional magnetic resonance imaging (fMRI) successfully disentangled neuronal pathophysiology of major depression (MD), but only a few fMRI studies have investigated correlates and predictors remission. Moreover, most used clinical outcome parameters from two time points, which do not optimally depict differential response times. Therefore, we aimed to detect remission in an antidepressant treatment study with 7 T fMRI, potentially harnessing advances detection power spatial specificity....
Abstract Background Studies investigating hippocampal volume changes after treatment with serotonergic antidepressants in patients major depressive disorder yielded inconsistent results, and effects on subfields are unclear. Methods To detail total subfield volumes, we conducted an open-label study escitalopram followed by venlafaxine upon nonresponse 20 unmedicated disorder. Before 12 weeks treatment, measured formation volumes ultra-high field (7 Tesla), T1-weighted, structural magnetic...
