Nicolas Guyon

Nicolas Guyon is a postdoc in the Faure/Mourot lab, and is interested in the molecular and neuronal circuit aspect of social behavior. After completing his Master’s degree in Cognitive Neuroscience at the Ecole Normale Supérieure, EHESS and University of Paris Cité, in France, Nicolas pursued a PhD in the lab of Marie Carlén at the Karolinska Institutet in Stockholm, Sweden. In his PhD project, he investigated the role of inhibitory GABAergic neurons expressing parvalbumin in prefrontal cortex circuitry. For this, he has used an array of advanced technologies to study specific neuronal cell types, circuits, and functions, including viral tracing, electrophysiology and optogenetics, in behaving rodents. At the Faure/Mourot lab, Nicolas will be developing strategies to gain non-invasive optical control over neurotransmitter receptors in the freely-moving mouse, for studies of neural circuits and behavior.
