3. Fig. 2
Electromyographic tracings taken at rest (top) demonstrate continuous motor unit activity in patient with tetanus, in comparison with absent activity in normal subject; jaw jerk (large spike) produces no change in either tracing. In normal subject, excitation of jaw jerk during voluntary contraction (bottom) produces inhibition of voluntary motor activity (Silent period). Note absence of inhibition in patient with tetanus. L = left side; R = right side.
