The extra-cellular cochlear microphonic is believed to be generated predominantly by outer
hair cells and therefore it would seem reasonable to assume that the presence of a cochlear …

The cochlear microphonic is a receptor potential believed to be generated primarily by outer
hair cells. Its detection in surface recordings has been considered a distinctive sign of outer …

Since the original description of the electrical responses of the cochlea by Wever and Bray,
la large quantity of information has been collected concerning these phenomena. It was …

Cochlear microphonic (CM) potentials were recorded, in guinea pig, with differential
electrodes before and after sectioning the medial efferent innervation at the level of the …

A survey of the literature shows that extensive studies': 10, 13, 16, 17 have been carried out
concerning the effects of sound exposure upon cochlear microphonics (CM), both from the …

Certain characteristics of the extracellular cochlear microphonic (CM) recorded by
intracochlear electrodes change in a bimodal manner as a function of prior acoustic …

Low-frequency microphonic potentials (100 Hz to 2000 Hz) have been measured in the first
turn of the guinea pig cochlea before and after a variety of manipulations of the cochlea …

Cochlear microphonic and summating potential recordings were obtained from preparations
where only either inner hair cells (first-turn recording) or outer hair cells (fourth-turn …

1. Recordings were made from chinchilla auditory nerve fibers after portions of the cochlear
outer hair cell (OHC) population were destroyed with the antibiotic kanamycin. In most cases …

This study assessed the contribution of the apical hair cells to hearing. Guinea pigs,
chinchillas and monkeys were behaviorally trained using positive reinforcement to respond …
