STIM is part of the Center for Neuroimaging Research (CENIR) and is dedicated to supporting research done on stereotactic data. It provides specific software development, data analysis, and expertise in neuroimaging processing and electrophyisiology. Its main application fields are deep brain stimulation(DBS), surgery (pre, per and post-operatively) and epilepsy. The YeB Atlas, developed by Jérome Yelnik and Eric Bardinet, is a strongsupport for data analysis. The core facility is involved in several DBS protocols in collaboration with other research institutes and industrials and coordinates the research protocols conducted on epileptic patients of the Pitié-Salpétrière. Interaction with La Pitié-Salpêtrière hospital departments such as neuroradiology, neurosurgery and neurology, adds up to the expertise of the core facility. Stereotactic softwares and models developed by the STIM platform are intended to be distributed to academic partners. CENIR STIM is part of the ICM core facility network (MRI, MEG/EEG, PANAM, PRISME…) which facilitates translational research projetcs.
