Research Theme

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). By focusing on the impact of social processes on the emotional brain, we define new biomarkers for MDD.

Social processes refer to a set of cognitive and neural mechanisms involved in our ability to interact with others and navigate the social world, including processes of face perception, self/other representation, social inclusion, etc. These processes are essential for adaptive behaviour. They are underpinned by brain systems that overlap with the emotional brain, a set of distributed cortical, subcortical, and limbic regions involved in emotional perception and regulation.

Our first objective is to advance knowledge on the reciprocal interaction of the brain systems dedicated to social processes and the emotional brain. We aim at clarifying the role of the visual cortex and of core regions of the emotional brain (amygdala, OFC) in the emotional perception of social and non social stimuli. We study how self-other perception influence the emotional regulation brain system, and the impact of social rejection and inclusion signals on emotional perception and regulation. Moreover, we develop a translational and reverse translational approach by applying our paradigms to healthy subjects and to subjects at risk of (viz. anhedonics) or with actual psychiatric disorders (viz. major depressive disorder, MDD). Dysfunction of the emotional brain is central to the physiopathology of MDD. Another objective is to uncover the role of social processes in the dysfunction of the emotional brain of depressed patients. More specifically, by studying the sensitivity to social signals and self-referential processes we will shed light on the interaction between the salience network and the emotional regulation network of the emotional brain and on their role in MDD.

Our project will contribute to unravel the functional architecture of the emotional brain and the social brain and to provide a brain-based definition of mental disorders. By focusing on the impact of social processes on the emotional brain, we aim at defining new biomarkers of MDD, with increased specificity. In the longer term, this may contribute to personalized medicine in the treatment of depression.

Lab rotation

Social exclusion in major depression: FMRI and EEG Study

Chercheur responsable: 

FOSSATI Philippe

Dates: 

2 January 2018 - 29 June 2018

Date limite de candidature: 

29 June 2018

Period

~ Jan-March 2018

~ April-June 2018

Project

The overall goal of this rotation is to analyze acquired fMRI in healthy subjects and depressed patients. Data included Stroop-EEG and social exclusion task in fMRI. We are interested in disentangling the role of Subgenual and saliency network in social exclusion in depressed patients (fMRI data).

MEG / EEG study of resting state networks and neurofeedback learning

Chercheur responsable: 

GEORGE Nathalie

Dates: 

2 January 2018 - 29 June 2018

Date limite de candidature: 

29 June 2018

Period

~ Jan-March 2018

~ April-June 2018

Project

This project aims at developing a neurofeedback protocol for future application to Parkinson’s disease. In a first stage, the project consists in setting up a simple neurofeedback protocol in healthy adults based on motor imagery and to study how neurofeedback learning impact on i) targeted brain activity ii) motor performance iii) brain networks recorded at rest.
