Neurological and psychiatric diseases
DRVC étudie les mécanismes impliquées dans le développement, la réparation, et le vieillissement du cerveau, avec comme modèles l'hippocampe et le cervelet, in vivo et in vitro.
Nous étudions les bases neurales de la mémoire spatiale grâce à des tests de navigation. La navigation est la capacité à se localiser dans un environnement et à trouver son chemin vers un but. La mémoire spatiale est une fonction centrale à cette capacité et son altération peut perturber la navigation. C’est par exemple le cas dans certaines pathologies de la mémoire telle que la maladie d'Alzheimer.
Le projet de l'équipe est d’identifier de nouvelles protéines et de nouveaux mécanismes impliqués dans le trafic neuronal de récepteurs, dans le but de caractériser de nouvelles cibles thérapeutiques dans le domaine de la dépression, la schizophrénie et d’autres pathologies neuronales et psychiatriques.
The PICNIC lab is devoted to the study of cognitive functions with an exclusive or prevalent development in humans, namely language and conscious cognition. The study of brain-damaged patients occupies a central position in our methodological approach. For the study of both language and consciousness, and with both patients and healthy subjects, we resort to state-of-the-art behavioural methods and multimodal brain imaging (MRI, high-density surface EEG and intracerebral implanted electrodes).
The goal of the research team is to analyze the roles played by environmental and genetic factors, as well as the interactions between these components, in the etiology and treatment of psychiatric disorders such as depression, anxiety and addiction. The main objective of the team is to identify cellular and molecular mechanisms underlying these pathologies which are associated with major dysfunctions of the monoamine and HPA systems and characterized by cellular plasticity alterations of different brain areas and in particular the hippocampus.
The long-term objective of this project is to apply high field MRI eventually combined with other neuroscience approaches, to develop physical (e.g. electric neurostimulation) and/or chemical (e.g. pharmacological delivery) devices of neuromodulation that target neuronal sites and manipulate specific aspects of cognition, motor behavior or consciousness, leading ultimately to the development of treatments for patients with related diseases (e.g. disorders of consciousness, Parkinson's disease...).
Our primary interest is to study the neural time course and correlates underpinning the processing of the early stages of social interactions. We have now set out to address several key issues important to our understanding of the processing of social interactions, for example (i) what is the biological function of spontaneous and involuntary facial reactions when facing emotional events; (ii) how and when do we perceive / decide that we are the target of a communicative intention (iii) how we (decide to) prepare an adapted motor response.
The SAN team gathers together three PIs with complementary expertise in affective neuroscience, social neuroscience, and psychiatry. Our project focuses on the functional neuroanatomy of the emotional brain. We study the brain systems of emotion detection, evaluation, and regulation, with an emphasis on how social processes (eg social inclusion) activate and regulate the emotional brain. Dysfunction of the emotional brain is central to many mental disorders and in particular to major depressive disorder (MDD).
Memory is a dynamical phenomenon, from the moment of encoding to retrieval. As shown in the mammalian brain, after encoding labile memories undergo consolidation, that is, they stabilize over time first in the hippocampus before being transferred to the neocortex for long-term storage (Battaglia et al., 2011, Frankland and Bontempi, 2005). In 1989, Gyorgy Buzsaki proposed the twostage model of memory consolidation, where each sequential phase of memory (encoding and consolidation) is related to different internal brain states (Buzsaki, 1989).
