title: Using speech and electrocorticography to map human auditory cortex.
abstract: Much less is known about the organization of the human auditory cortex compared to non-human primate auditory cortices. In an effort to further investigate the response properties of human auditory cortex, we present preliminary findings from human subjects implanted with depth electrodes in Heschl's gyrus (HG) as part of their neurosurgical treatment of epilepsy. Each subject had electrocorticography (ECoG) responses taken from medial and lateral HG in response to both speech and non-speech stimuli, including during speech production. Responses were somewhat variable across subjects, but posteromedial HG demonstrated frequency following responses to the stimuli in all subjects to some degree. Results and implications are discussed.
