Our laboratory investigates the neural mechanisms underlying decision making, motivation and reward processing in humans, using concepts from cognitive neuroscience, psychology and behavioral economics. We use experimental tools such as model-based functional Magnetic Resonance Imaging, intracranial electrophysiological recordings and pharmacological manipulations to understand the computational processes involved when making a choice. Our goals are to understand the functional organization of the prefrontal cortex in humans, the various functions that the reward dopaminergic system exerts on cognition and motivation and the neural mechanisms underlying dysfunctions of these two systems in patients with neurological or psychiatric illnesses (Parkinson’s disease, patients with focal prefrontal cortex lesions, schizophrenia and pathological gambling). In parallel, we are also studying how individual variations in hormones and genes influence reward processing and decision-making.

Open positions

Applications are invited for a postdoctoral position to study neuroeconomics, decision making, motivation and reward processing using fMRI in healthy subjects and patients with neurological disorders.

Ants collectively build nests whose size can reach several thousand times that of individual ants and whose architecture is sometimes highly complex. However, their ability to coordinate several thousand individuals when building their nests remains a mys…

When an unexpected event occurs, it is often necessary to act, even if one does not control all of the consequences. According to scientists in the Laboratoire Neurosciences Paris-Seine (CNRS/UPMC/INSERM), mice will display their curiosity in a situation …
