Tourette's syndrome (TS) is a debilitating and severe syndrome whose pathophysiology remains unclear.
In order to precise the cortical regions involved in the generation of tics, investigators will realize an electroencephalogram (EEG) recording in the frontal cortex of TS patients in ecological conditions (EEG-holter). Activity changes will be correlated with event markers of tics and neurovegetative parameters. Statistical analyses will be compared between epochs of EEG recording with tics and without tics. The aim is to define the cortical regions involved in the genesis of tics in order to consider new targets for cortical stimulation.
