Figure 1

Electrophysiological Tests. The Figure shows: A) The neuromuscular responses evoked by transcranial electrical stimulation of the trigeminal motor roots; B) The jaw jerk reflex when the mandible was kept in rest position. Note the relative degree of symmetry between the sides; C) The jaw jerk reflex when the mandible was kept in occlusal position (intercuspal position). Note the high degree of asymmetry between the sides.
