Nom du laboratoire: Émotions, IRMf, trouble de stress post-traumatique
Groupe thématique: Stress, anxiété, dépression et suicideDivision: Neuroscience humaine
Notre compréhension actuelle des troubles reliés au stress, y compris le trouble de stress post-traumatique (TSPT), les phobies, les crises de panique et l’anxiété généralisée, résulte de l’étude de la façon dont le cerveau traite la peur.
Jorge Armony, Ph.D., mène une recherche sur la façon dont le cerveau détecte dans l’environnement des stimuli qui peuvent signaler la présence de menaces ou de dangers et comment ce mécanisme interagit avec d’autres processus tels que la conscience, l’attention, et la mémoire.
Dans sa quête de réponses, Jorge Armony se sert de plusieurs techniques de recherche dernier cri dont l’imagerie par résonance magnétique fonctionnelle (IRMf), les mesures comportementales et physiologiques (i.e., conductivité de la peau et fréquence cardiaque), et également la modélisation informatique.
Ses contributions à la compréhension des troubles psychiatriques provenant d’un mauvais fonctionnement du système de la peur sont significatives. Ainsi, Jorge Armony a récemment révélé des liens comportementaux et anatomiques dans la modulation de l’attention spatiale par le biais des émotions en se servant d’un paradigme pour le conditionnement de la peur.
Ces percées mettent encore plus en évidence le rôle des amygdales dans le traitement de la peur et servent à profiler les rôles respectifs des cortex frontal, pariétal, orbito-frontal latéral dans l’attention spatiale.
En 2002, Jorge Armony s’est vu attribuer une chaire de recherche du Canada (niveau 2) en neurosciences affectives.
Laboratoire de Jorge Armony, Ph.D.
Le laboratoire utilise l’imagerie par résonance magnétique fonctionnelle (IRMf) pour étudier les bases neuronales du traitement des émotions chez l’humain.
Les chercheurs explorent la façon dont la détection de stimuli environnementaux (représentant un danger imminent par exemple) interagit avec d’autres processus cérébraux, tels l’attention, la mémoire et la conscience.
Cette recherche est particulièrement pertinente pour la compréhension de certains troubles anxieux, notamment le trouble de stress post-traumatique (TSPT).

Healthy subjects were scanned using a fast, high-resolution functional magnetic resonance imaging (fMRI) multiband sequence while they performed a two-alternative forced-choice emotion judgement task on faces and vocal utterances conveying explicit anger or fear, as well as ambiguous ones. Critically, the latter was specific to each subject, obtained through a morphing procedure and selected prior to scanning following a perceptual decision-making task. Behavioural results confirmed a greater task-difficulty for subject-specific ambiguous stimuli and also revealed a judgement bias for visual fear, and, to a lesser extent, for auditory anger. Imaging results showed increased activity in regions of the salience and frontoparietal control networks (FPCNs) and deactivation in areas of the default mode network for ambiguous, relative to explicit, expressions. In contrast, the right amygdala (AMG) responded more strongly to explicit stimuli. Interestingly, its response to the same ambiguous stimulus depended on the subjective judgement of the expression. Finally, we found that behavioural and neural differences between ambiguous and explicit expressions decreased as a function of state anxiety scores. Taken together, our results show that behavioural and brain responses to emotional expressions are determined not only by emotional clarity but also modality and the subjects' subjective perception of the emotion expressed, and that some of these responses are modulated by state anxiety levels.},

Twenty-four French participants listened to short utterances describing a painful event, which were either produced in a neutral-sounding or complaining voice by both in-group (French) and out-group (French Canadian) speakers.

abstract = {Somatosensory experience is an important component of emotion, playing a prominent role in many traditional emotion theories. Nonetheless, and despite the extensive literature on the influence of individual differences in emotional processing, the relation between personality traits and emotion-related somatosensation has received little attention. Here, we addressed this question in a large sample of healthy individuals through the "bodily maps of emotion" behavioural paradigm, in which participants indicated the location and extent of their body sensations for the 6 basic and 4 additional social emotions (contempt, envy, pride, shame). We found that emotional somatosensation in specific body areas, including the heart, the stomach, and the head, was related to specific personality factors, particularly antisocial attitudes and impulsivity. Moreover, the similarity of individual participants' maps to the group-average was likewise negatively correlated with antisocial tendencies.

Somatosensory experience is an important component of emotion, playing a prominent role in many traditional emotion theories. Nonetheless, and despite the extensive literature on the influence of individual differences in emotional processing, the relation between personality traits and emotion-related somatosensation has received little attention. Here, we addressed this question in a large sample of healthy individuals through the "bodily maps of emotion" behavioural paradigm, in which participants indicated the location and extent of their body sensations for the 6 basic and 4 additional social emotions (contempt, envy, pride, shame). We found that emotional somatosensation in specific body areas, including the heart, the stomach, and the head, was related to specific personality factors, particularly antisocial attitudes and impulsivity. Moreover, the similarity of individual participants' maps to the group-average was likewise negatively correlated with antisocial tendencies. Overall, our results suggest that differences in individuals' sensitivity to somatosensation from different body areas, as well as the typicality of their topographical patterns, may partly underlie variation in higher-order social and affective traits.
