  • Unité de recherche

Founded in 2010 and located in the heart of the Pitié-Salpêtrière University Hospital, the first neurology center in France, the ICM represents a strong link between fundamental research and the clinical world. The Institute gathers more than 700 researchers and clinicians, 10 cutting-edge core facilities and 1000m² dedicated to startup incubation. Its aim is to produce ambitious research by combining scientific creativity and therapeutic purpose. Its innovative model brings together patients, doctors and researchers in a transversal approach of research that promotes collaborations and accelerates the discovery of medical innovations. Partnerships between the public and private sectors at the ICM have allowed to rapidly translate discoveries into therapeutic solutions for patients. Since 2017, the ICM is the first health partner of Station F, providing a competitive advantage in the field of connected health.

Organization

ICM is organized in four major fields: molecular and cellular, neurophysiology, cognition, clinical and translational. High flexibility between these fields is a cornerstone of our scientific and medical development.

ICM teams working in the field of molecular and cellular science are involved in a collaborative effort to understand normal brain and spinal cord development as well as what leads to their malfunction in neurological and psychiatric illness. Teams are focused on deciphering how genetics play a role, on dissecting molecular mechanisms, identifying the role of different cell types, and understanding complex cellular interactions in normal and pathological conditions.

The team working in this field aim at achieving a better understanding of neuron physiology and networks in normal and pathological conditions. They share approaches based on molecular and cellular processes, electrophysiological and optic recording, optogenetics and neural activity manipulation using transcranial magnetic stimulation, as well as IT models to link physiological recordings together.

The teams in this research areas combine structural, electrophysiological, and functional studies to understand how neural networks function in the brain and their role in behavior and cognitive processes in both healthy individuals and patients with neurological and psychiatric disorders.

The main objective in this research area is to develop markers and therapy for neurological and psychiatric diseases, from identification on simple models in laboratories to clinical trials with patients at ICM’s Clinical Investigation Center and throughout the Institute. Breakthroughs in this field are achieved in close collaboration with other areas at ICM.
