Figure 13From: Mechanisms of human cerebellar dysmetria: experimental evidence and current conceptual basesLong latency electromyographic (EMG) responses to stretches of the first dorsal interosseous muscle in a cerebellar patient (black line) and in a control subject (grey line). Latencies of averaged rectified EMG responses are normal, but the M3 response is increased in the cerebellar patient. Surface EMG rectified and averaged 200 times. Responses are calibrated in arbitrary units (a.u.).Back to article page
