Webinar #6: “Cortico-basal ganglia gamma and beta synchronization during action control” by Dr. Petra Fischer

October 20, 2020, 16:00 CEST | by Dr. Petra Fischer, University of Oxford

Our Expert Talks webinar series finally continues. We are very happy to announce Dr. Petra Fischer as our next speaker. In this webinar Dr. Fischer will talk about cortico-basal ganglia gamma and beta synchronization during action control. The webinar will be held on October 20, 16:00 CEST. Register now!

About the talk

”Dysfunctional cortico-basal ganglia (BG) processing can result in severely disrupted movement control as observed in Parkinson’s disease, Huntington’s disease and dystonia. Simple ballistic movements are accompanied by increased synchronization at relatively high frequencies in the gamma range (60-90 Hz) while slower beta-rhythmic activity (13-30 Hz) is suppressed. Gamma and beta oscillations thus have been conceptualized to represent pro-kinetic and anti-kinetic processes, respectively. To uncover how the cortico-BG network supports more complex actions we recorded EEG activity and subthalamic nucleus (STN) local field potentials in Parkinson’s patients in the following two tasks: Rapid stopping of a continuous finger tapping movement and smooth transitions between stable muscle contractions.”
