The authors describe a case of tricyclic‐induced myoclonus in a 41‐year‐old depressed woman showing spike activity on electroencephalogram. The results of jerk‐locked averaging and somatosensory evoked potential (SEP) are presented. No jerk‐related cortical spikes and enlarged evoked potentials were observed. These findings suggest that tricyclic‐induced myoclonus may not be associated with excitability in the transcortical pathways detectable by SEP.
