Abstract:
Thesis advisor: John P. Christianson<br>In social species, animals must detect, evaluate and respond to the states of other individuals in their group. A constellation of gestures, vocalizations, and chemosignals enable animals to convey affect and arousal to others in nuanced, multisensory ways. Observers integrate such social information with environmental cues and internal physiology to general social behavioral responses via a process called social decision-making. The mechanisms and anatomical correlates of social decision-making, particularly those that allow behavioral responses to othe

Abstract:
Influential models highlight that insular cortex integrates cognitive, affective, sensorimotor and autonomic signals to create unified perceptual experiences or "feeling states". One challenge in developing a satisfactory neuropsychological model of insula function is to account for its involvement across these different domains which require access across multiple functional circuits. This thesis combines behavioural, psychophysiological, functional neuroimaging and lesion methods to inform and extend current models of integration in the insula. In the first two experimental chapters, the int

Abstract:
The prefrontal cortex (PFC) is considered a critical node in the neural circuitry underlying drug-seeking behaviors. However, the mechanisms by which this region influences drug seeking and whether or not the lateral PFC mediates cocaine or heroin seeking are questions that have yet to be answered. To expand on the role of the PFC in drug seeking, rats were trained on either heroin or cocaine self-administration for a minimum of 12 days before undergoing extinction training and subsequent reinstatement tests (cued and drug-prime). All pharmacological manipulations were delivered immediately pr

Le cortex insulaire est le cinquième lobe du cerveau en charge de l'intégration de nombreuses fonctions cognitives, sous-tendues par une organisation cytoarchitectonique etune connectivité aussi riche que complexe. Ce travail vise à évaluer la connectivité fonctionnelle insulaire du cerveau humain par le biais de stimulation électrique intra-cérébrale et de potentiels évoqués cortico-corticaux (PECC) réalisés chez des patients explorés en stéréoélectroencéphalographie (SEEG) pour une épilepsie partielle réfractaire.

Abstract:
Thesis advisor: John P. Christianson<br>Accurate discrimination between safety and danger is necessary for survival, but is aberrant in individuals with post-traumatic stress disorder (PTSD). Despite its clinical relevance, very little is known about the cognitive and neural processes that underlie safety learning. Understanding how cues become safety signals is critical to understanding the impairments in fear modulation observed in individuals with PTSD. PTSD is more prevalent in women than men, and while research on sex differences in safety learning is limited, there is substantial evidenc

Abstract:
Les sensations en provenance de notre corps se combinent pour donner lieu à des perceptions extrêmement variées, pouvant aller de la brûlure douloureuse au toucher agréable. Ces deux types d'informations dites nociceptives et non nociceptive sont traitées au sein du système nerveux somatosensoriel. Dans ce travail de thèse, nous avons modélisé et caractérisé l'activité électrique du cortex operculo-insulaire au sein des réseaux somatosensoriels non-douloureux et nociceptif, grâce à des enregistrements non-invasifs chez l'Homme.

Abstract:
L’ADHD (Attention-deficit/hyperactivity disorder) est une maladie du développement caractérisée par l’impulsivité, l’hyperactivité, et l’inattention. Les voies neuronales impliquées dans ces déficits indiquent des dysfonctionnements dans les réseaux catécholaminergiques frontal-sous-corticaux, impliquant l'innervation dopaminergique et noradrénergique. Des études récentes ont mis en évidence une hypersensibilité à la douleur chez les patients ADHD et soulignent une possible comorbidité entre l’ADHD et la douleur.

Abstract:
BACKGROUND AND OBJECTIVES: Obesity is emerging as the most significant health concern of the twenty-first century. A wealth of neuroimaging data suggest that weight gain might be related to aberrant brain function, particularly in prefrontal cortical regions modulating mesolimbic addictive responses to food. Nevertheless, food addiction is currently a model hotly debated. Here, we conduct a meta-analysis of neuroimaging data, examining the most common functional differences between normal-weight and obese participants in response to food stimuli.

Abstract:
L’oxaliplatine, anticancéreux utilisé pour le traitement du cancer colorectal, est responsable d’une neurotoxicité périphérique dose-limitante affectant une grande majorité de patients. La neurotoxicité de l’oxaliplatine se présente sous deux formes : une forme immédiate, se traduisant par des paresthésies transitoires, et une forme retardée et cumulative, caractérisée par l’apparition d’une neuropathie périphérique douloureuse fortement invalidante. A l’heure actuelle, la prise en charge des douleurs neuropathiques est souvent incomplète, principalement à cause du manque de traitements effica
