Lateralizing Value of the Auditory Aura in Partial Seizures

Abstract

Auditory aura is a rare symptom in partial epilepsy. The perception of the auditory sensation referred to one ear is not a unique lateralizing sign for the contralateral temporal neocortex. Complex hallucinations with verbal content and negative illusion may lateralize seizure onset in the dominant hemisphere. The role of laterality for musical hallucinations remains unclear as it depends on individual musical ability and hemispheric dominance for music.
