To clarify the cortical mechanisms involved in motor inhibition, modulation of cortical rhythms around 20 Hz during voluntary muscle relaxation was compared to that during muscle contraction in ten normal volunteers, using a whole head type neuromagnetometer. Each subject relaxed or contracted the right forearm muscles, from which electromyograms were recorded. After band-pass filtering magnetoencephalographic signals into frequency bands of 6–10, 10–14, 14–18, 18–22, 22–26, and 26–30 Hz, the… CONTINUE READING
