Interconnections in superior temporal cortex revealed by musicogenic seizure propagation
Musicogenic epilepsy (ME) is an intriguing epilepsy syndrome with estimated prevalence of 1 per million . Seizures are precipitated by complex and usually highly specific stimuli. ME has been the topic of several excellent reviews [2, 3], but reports of comprehensively studied patients are scarce . Notably, ME can provide insights in auditory processing and seizure-triggering mechanisms in humans. We present here a patient with non-lesional ME, whose seizure initiation and propagation shed light on interconnections within the superior temporal cortex.
A 42-year-old right-handed professional composer started having seizures at 11 years. Seizures became difficult-to-control after he entered music school. Stereotyped auras were consistently triggered by songs with familiar melody and lyrics. “Happy Birthday” and songs by Elton John were especially provocative, whereas jazz/instrumentals had no effect. Auras consisted of buzzing or muffled sounds several times/week,...
