⩥The auditory or the cochlear nerve is a part of the ____________
nerve. Answer: vestibulocochlear
⩥IHCS are __-__% afferent Answer: 90-95
⩥The auditory nerve relays information about ____,_____ and _____ of
a sound after cochlear processing. Answer: FIT frequency, intensity, and
timing.
⩥______ _______ is required for optimal functioning of the auditory
nerve. Answer: neural synchrony
⩥afferent Answer: inner hair cells
⩥A group of neuron cell bodies in the modiolus. Answer: spiral ganglion
⩥type 1 nerve fibers are Answer: myelinated
⩥The auditory nerve passes through the internal auditory meatus. •The
AN is _____ cm in humans Answer: 2.5
, ⩥low spontaneous fibers encode Answer: louder sounds
⩥If the spontaneous discharge rate is known, then the _______ threshold
can be determined. Answer: neural
⩥The minimum stimulus level that is required to cause an increase in the
spike rate above the spontaneous rate. Answer: neural threshold
⩥Is frequency coded in 2 ways? list them Answer: place theory and
phase locking/temporal theory
⩥is coded by the firing rate of nerve cells. Answer: frequency
⩥Phase locking for AN is around Answer: 1-2 khz maximum
⩥In quiet, most fibers in the auditory nerve show a background level of
firing called Answer: spontaneous activity
⩥Many fibers (perhaps 90%) have _____ spontaneous rates. - quite
sensitive and show an increase in firing rate in response to a low
stimulus level. Answer: high
