OBJECTIVE To study the cortical physiology of fast repetitive finger movements. METHODS We recorded steady-state movement-related magnetic fields (ssMRMFs) associated with self-paced, repetitive, 2-Hz finger movements in a 122-channel whole-head magnetometer. The ssMRMF generators were determined by equivalent current dipole (ECD) modeling and co-registered with anatomical magnetic resonance images (MRIs). RESULTS Two major ssMRMF components occurred in proximity to EMG onset: a motor field… CONTINUE READING
