HST.721 The Peripheral Auditory System (MIT) HST.721 The Peripheral Auditory System (MIT)

Description

In this course, experimental approaches to the study of hearing and deafness are presented through lectures, laboratory exercises and discussions of the primary literature on the auditory periphery. Topics include inner-ear development, functional anatomy of the inner ear, cochlear mechanics and micromechanics, mechano-electric transduction by hair cells, outer hair cells' electromotility and the cochlear amplifier, otoacoustic emissions, synaptic transmission, stimulus coding in auditory nerve responses, efferent control of cochlear function, damage and repair of hair-cell organs, and sensorineural hearing loss.

HST.720 Physiology of the Ear (MIT) HST.720 Physiology of the Ear (MIT)

Description

Topics for this course are based primarily on reading and discussions of original research literature that cover the analysis as well as the underlying physical and physiological mechanisms of acoustic signals in the auditory periphery. Topics include the acoustics, mechanics, and hydrodynamics of sound transmission; the biophysical basis for cochlear amplification; the physiology of hair-cell transduction and synaptic transmission; efferent feedback control; the analysis and coding of simple and complex sounds by the inner ear; and the physiological bases for hearing disorders.
