Oscillatory Activity in Basal Ganglia Circuits During Normal and Pathological Movement
The expression of hypokinetic and hyperkinetic motor symptoms is accompanied by pathological synchronous oscillations of neuronal activity in this cortico-subcortical network with a wide frequency range. The purpose of this research is to study cortico-subcortical oscillations and their synchronization in two pathologies emblematic of hypokinetic (Parkinson's disease) and hyperkinetic (epilepsies) phenomena using a simple motor task and comparing different situations.
