Study of the Correlation Between Cortical Excitability and Cytoarchitectonics of Prefrontal Cortex in Healthy Adult Participants, Using Transcranial Magnetic Stimulation Coupled to EEG and High-field MRI

For the TMS session, participants will be positioned on a chair, in a seated position. They will be equipped with an EEG cap 64 active electrodes, using gel to ensure good measurements of brain activation, and a sensor on the forehead to measure the location of the head in space for the neuronavigation system. They will also wear headphones generating white noise to mask the TMS coil noise. Preparation time for the EEG acquisitions is estimated at 30 min. The TMS coil will be shaped in 8 for good spatial resolution. It will be positioned on the participant's head using a robot (approved medical CE) allowing good targeting accuracy and stability during the experiment. The stimulation target will be defined beforehand on the participant's MRI, and the robot will read this information to position itself.
