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 articulation between cognition and consciousness

We use MEG and behavior to understand how the neural processes performing perceptual (ie, figure/ground) or cognitive (ie, attentional selection) are articulated with those giving rise to visual subjective experience.

How brain-body loops may participate to the emergence of consciousness

The cognitive neuroscience lab conducts researchs to understand the neural bases of Action and related cognitive processes along several dimensions: motor, linguistic, social and intentional. We especially study the brain functional architecture and neuronal computations underlying these processes using modern brain imaging techniques (IRMf, EEG-MEG), experimental psychology techniques and mathematical / computational modeling.
