[Pathophysiology of cortical myoclonus].

Myoclonus is one of the common movement disorders in clinical practice, and its differential diagnosis is important. Usually, myoclonus can be classified into cortical, subcortical, brain stem, spinal and peripheral, based on its pathogenesis. Especially, cortical myoclonus is closely associated with epilepsy (myoclonic epilepsy) and has been studied extensively so far. Here, we will review the pathogenesis of cortical myoclonus from the viewpoint of clinical neurophysiology.
