title: The origin of myoclonus and periodic synchronous discharges in subacute sclerosing panencephalitis.
abstract: We report here a case of a patient with subacute sclerosing panencephalitis (SSPE) and we have analyzed periodic events using dipole tracing methods to clarify the origin of periodic synchronous discharges and myoclonus. Both source generators were located in the subcortical part of the cerebrum, an area adjacent to the thalamus. Although the pathophysiology of periodic events in SSPE has been controversial, dipole tracing methods may contribute to clarify the origin of periodic events in SSPE.
