Musical Automatisms

A few cases were collected together to see if ictal humming or singing had an anatomic correlate. Ictal singing seemed to correlate with right prefrontal seizures. Humming arose from temporal seizures. Singing seems to lateralize more to the right including "the superior temporal gyrus, the inferior central operculum, and particularly the inferior frontal gyrus."
