<dcterms:abstract xml:lang="fr">Les progrès en neuroanatomie et connectivité cérébrale ont souvent permis de progresser dans la compréhension des maladies neuropsychiatriques. De récentes études ont montré que la queue de l’aire tegmentale ventrale (tVTA) est le contrôle inhibiteur principal des systèmes dopaminergiques et participe également au contrôle moteur, au codage des erreurs de prédiction et aux réponses à des stimulus aversifs, faisant d’elle un acteur potentiel dans les pathologies associées comme la dépression et les troubles du stress post-traumatique. Pour comprendre son rôle dans ces pathologies, nous avons combiné des techniques d’analyses moléculaires et d’évaluation comportementale. Nos résultats montrent une plasticité majeure des synapses glutamatergiques de la tVTA, augmentant significativement l’activité de la structure. En bloquant la transmission glutamatergique locale, de manière préventive ou thérapeutique, nous avons mis en évidence le rôle crucial de la tVTA dans la stratégie d’adaptation comportementale au stress. Ce projet amène une caractérisation nouvelle du rôle de la tVTA dans les symptômes cognitifs associés aux troubles de l’humeur.</dcterms:abstract>
<dcterms:abstract xml:lang="en">Progresses in neuroanatomy and brain connectivity have often led to a better understanding of neurodegenerative and neuropsychiatric diseases. Recent studies have shown that the tail of the ventral tegmental area (tVTA) is the primary inhibitory control of dopaminergic systems, and also participates in motor control, prediction error coding and responses to aversive stimuli and drugs of abuse, making it a potential player in associated pathologies such as depression and post-traumatic stress disorders. We have combined molecular analysis and behavioral assessment techniques with a therapeutic and preventive pharmacological approach. Our results show a major plasticity of the glutamatergic synapses of the tVTA, significantly increasing the activity of the structure. By pharmacologically blocking local glutamatergic transmission, either preventively or therapeutically, we have highlighted the crucial role of the tVTA in behavioral adaptation to stress. This project provides a novel characterization of the role of tVTA in cognitive symptoms associated with mood disorders.</dcterms:abstract>
