Research Theme

 Our research is focused on encoding learning and memory in the basal ganglia, a set of subcortical nuclei implicated in the adaptive control of behavior. Reciprocally connected with the cerebral cortex and the limbic system, the basal ganglia participate to the detection of environmental cues and to the selection of appropriate actions based on motivation and expectancy of reward.

The pathological dysfunction of basal ganglia leads to major motor and cognitive disorders (Parkinson’s disease, OCDs Tourette’s syndrome, addiction…) for which no fully satisfying treatments are available yet.

We study various aspects of the dynamic organization and synaptic interactions underlying the dynamic properties of the basal ganglia network and the changes of these properties in animal models of human pathologies. We are using a multidisciplinary approach combining electrophysiology (in vitro multi-patch-clamp and in vivo recordings), fast-cyclic voltammetry, 2-photon imaging, single-cell RT-PCR and immunohistochemistry, using in vitro and in vivo model. The complementary conceptual and technical expertise of the members of the team together with the collaborations we already established with groups of mathematicians, molecular biologists, clinicians and pharmaceutical industry allow us to investigate the normal and pathological functions of the basal ganglia at the different levels of complexity of the neuronal network. 

1) The neuronal dynamics and synaptic plasticity (STDP) within the basal ganglia and cortical networks.

2) The neuron-glia crosstalk: we analyze the contribution of neurotransmitter uptake by astrocytes on corticostriatal information processing.

3) The physiology and pathophysiology of motor and cognitive properties link to dopamine and endocannabinoids.
