Jerk-locked averaging and somatosensory evoked potential in tricyclic-induced myoclonus: a case report.
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.
