Recent frameworks in cognitive neuroscience and behavioral neurology underscore interoceptive priors as core modulators of negative emotions. However, the field lacks experimental designs manipulating priming emotions via interoception exploring their multimodal signatures neurodegenerative models. Here, we designed a novel task that involves control-exteroceptive conditions followed by post-interoception post-exteroception facial emotion recognition (FER). We recruited 114 participants,...
Interoception (the sensing of inner-body signals) is a multi-faceted construct with major relevance for basic and clinical neuroscience research. However, the neurocognitive signatures this domain (cutting across behavioral, electrophysiological, fMRI connectivity levels) are rarely reported in convergent or systematic fashion. Additionally, various controversies field might reflect caveats standard interoceptive accuracy (IA) indexes, mainly based on heartbeat detection (HBD) tasks. Here we...
Action verbs are critically embodied in motor brain networks. In Parkinson's disease (PD), damage to the latter compromises access such words. However, patients not fully incapable of processing them, as their performance is far from floor level. Here we tested hypothesis that action-verb PD may rely on alternative disembodied semantic circuits. Seventeen and 15 healthy controls listened action nouns during functional MRI scanning. Using cluster-mass analysis with a permutation test,...

Abstract Multiple sclerosis (MS) patients present several alterations related to sensing of bodily signals. However, no specific neurocognitive impairment has yet been proposed as a core deficit underlying such symptoms. We aimed determine whether MS changes in interoception—that is, the monitoring autonomic information—a process that might be various dysfunctions. performed two studies 34 relapsing–remitting, early‐stage and 46 controls matched for gender, age, education. In Study 1, we...
Abstract Interoception, the sensing of visceral body signals, involves an interplay between neural and autonomic mechanisms. Clinical studies into this domain have focused on patients with neurological psychiatric disorders, showing that damage to relevant brain mechanisms can variously alter interoceptive functions. However, association peripheral cardiac‐system alterations neurocognitive markers interoception remains poorly understood. To bridge gap, we examined multidimensional in early...
Abstract Biomarkers represent a critical research area in neurodegeneration disease as they can contribute to studying potential disease‐modifying agents, fostering timely therapeutic interventions, and alleviating associated financial costs. Functional connectivity (FC) analysis represents promising approach identify early biomarkers specific diseases. Yet, virtually no study has tested whether FC prove be reliable reproducible across different centers. As such, their implementation remains...
Social feedback can selectively enhance learning in diverse domains. Relevant neurocognitive mechanisms have been studied mainly healthy persons, yielding correlational findings. Neurodegenerative lesion models, coupled with multimodal brain measures, complement standard approaches by revealing direct multidimensional correlates of the phenomenon. To this end, we assessed socially reinforced and non-socially 40 participants as well persons behavioural variant frontotemporal dementia (n =...
Lack of access to appropriate clothing sizes can negatively impact body image and self-esteem. This study aimed assess the relationship between access, image, 443 participants (42 male) completed a sociodemographic questionnaire, scale, Body Appreciation Scale, Rosenberg Self-Esteem Eating Attitudes Test, Esteem Questionnaire. Data analysis focused on women without eating disorder risk, with comparisons made those at risk disor-ders men using matched sub-sample (in BMI, age, size)....
Above and beyond the critical contributions of perisylvian regions to language, neural networks supporting pragmatic aspects verbal communication in native non-native languages (L1s L2, respectively) have often been ascribed right hemisphere (RH). However, several reports shown that left-hemisphere activity associated with domains (e.g., prosody, indirect speech, figurative language) is comparable or even greater than observed RH, challenging proposed putative role latter for relevant...
ABSTRACT Objective Neurological nosology, based on categorical systems, has largely ignored dimensional aspects of neurocognitive impairments. Transdiagnostic approaches interoception (the sensing visceral signals) may improve the descriptions cross-pathological symptoms at behavioral, electrophysiological, and anatomical levels. Alterations cardiac (encompassing multidimensional variables such as accuracy, learning, sensibility, awareness) its neural correlates (electrophysiological...
Deficits in cognitive functions dependent upon the integrity of prefrontal cortex have been described Multiple Sclerosis (MS). In a series studies we shown that fluid intelligence (g) is substantial contributor to frontal deficits and that, for some classical "executive" tasks, were entirely explained by g. However, another group tasks remained once g was introduced as covariate. This second set tests included multitasking theory mind tasks. present study, aimed at determining role seen...
Recent embodied cognition research shows that access to action verbs in shallow-processing tasks becomes selectively compromised upon atrophy of the cerebellum, a critical motor region. Here we assessed whether cerebellar damage also disturbs explicit semantic processing pictures and its integration with ongoing responses. We evaluated cognitively preserved 33-year-old man severe dysplastic gangliocytoma (Lhermitte-Duclos disease), encompassing most right cerebellum posterior part left...
Hypertensive disease (HTD), a prominent risk factor for cardiovascular and cerebrovascular diseases, is characterized by elevated stress-proneness. Since stress levels are underpinned both cardiac neural factors, multidimensional insights required to robustly understand their disruption in HTD. Yet, despite crucial relevance, heart rate variability (HRV) multimodal neurocognitive markers of HTD remain controversial unexplored respectively. To bridge this gap, we studied cardiodynamic as well...
Previous single-case reports in posterior cortical atrophy (PCA) have shown preserved nonconscious visual recognition despite the absence of explicit recognition. In this study, we investigated three levels both a female patient with PCA and control group during presentation neutral, positive, negative affective stimuli. Our results confirmed profile impaired intact psychophysiological responses patient. addition, she was able to implicitly recognize valence intensity arousal these We...
Neurodevelopmental evidence suggests that children's main decision-making strategy is to avoid options likely induce punishment. However, the cognitive and affective factors contributing avoidance high punishment frequency remain unknown. The present study explored psychophysiological, cognitive, metacognitive processes associated with sensitivity frequency. We evaluated 54 participants (between 8 15 years old) a modified Iowa Gambling Task for children (IGT-C) which included varying...
Purpose Binge eating involves consuming unusually large amounts of food that another person would not eat in the same period and setting. Emotional consumption response to a series negative emotions. Associated with both are emotional regulation difficulties. People can also be susceptible overeating because hedonic nature certain foods, such as those high fat sugar. We aimed analyze differences between increasing levels binging eating, its relationship regulation, body mass index (BMI)....
One of the consequences pandemic is that throughout 2020 virtual interactions largely replaced face-to-face interactions. Though there are few studies how social media impacts body image perception across genders, research suggests socializing through a self-body might have distinct implications for men and women. In an online study, we examined whether type pressure body-ideal exert pressures on members X, Y, Z generations. Results showed affected satisfaction significantly more than other...

People’s estimation of body weight relies on a process social comparison where people overestimate their compared to other people’s. This distortion is often exacerbated in patients with eating and image disorders. Frequent results an attentional shift towards one’s body, which reinforces gain concerns dissatisfaction, increases the risk developing A further consequence that has not been explored how distortions perception interfere from third-person point view (i.e., when comparing people)....
