Time-course of coherence in the human basal ganglia during voluntary movements.

摘要: We are interested in characterizing how brain networks interact and communicate with each other during voluntary movements. recorded electrical activities from the globus pallidus pars interna (GPi), subthalamic nucleus (STN) motor cortex wrist Seven patients dystonia six Parkinson’s disease underwent bilateral deep stimulation (DBS) electrode placement. Local field potentials DBS electrodes scalp EEG placed over cortices were while performed externally triggered self-initiated The coherence calculated between STN or GPi was found to be coupled its power both beta gamma bands. association of suggests that a coupling neural activity basal ganglia is required for execution Finally, we propose mathematical model involving oscillators which provides possible explanation inter-regional takes place.
