Fields of research

Neurophysiology / systems neuroscience

Research Theme

The Team is specialized in integrative neuroscience. Using the barrel cortex of rodents as a system model, our research is centered on the study of neuronal processes responsible for the coding of tactile sensory information and perception, as well as their regulation through the interaction of the animal with the environment. We are interested in the propagation and integration of neuronal information in the primary somatosensory cortex and subcortical somatosensory relays, and the emergence of collective properties in response to spatially distributed stimuli on the receptor surface. In addition, we study the functional and synaptic adaptation within the framework of Hebbian and non-Hebbian plasticity algorithms. We include in this research the study of permissive factors linked to the attentional and behavioral state of the animal which are mediated by ascending neuromodulatory systems. Our research involves a combination of cutting edge techniques (multi-electrode electrophysiology, functional imaging (VSD), optogenetics, multiple-whisker stimulation, behaviour) in acute and chronically implanted preparations.
