bineural interactions are accomplished in __ ways
10.
1 point
anterior ventral cochlear nucleus, neuronal type found in the cochlear nucleus
11.
1 point
each primary auditory neuron is sensitive to only one frequency called the

small, unmyelinated, properties are unknown because they cannot be recorded - about 5%
15.
1 point
the inferior colliculus is located in
16.
1 point
myelinated, respond to specific frequencies - about 95%

(2 words)
21.
1 point
intraural time differences occur with
22.
1 point
the ___________ __________ is the largest tract of auditory nerve fibers that carry info (2)
23.
1 point
info from the right and left ear come together in a unified impression, part is sound localized and lateralized
24.
1 point
1st place in auditory system, binaural interaction & coding sound
25.
1 point
the dorsal cochlear nucleus contains stellate cells, these human structure differ greatly from non-humans
26.
1 point
efferent control, inner hair cells, mostly ipsilateral
27.
1 point
the cochlear division of cranial nerve V III carries info from the ______ to the brain
28.
1 point
______ are maintained at all levels as well as frequency selectivity, timing, and intensity patterns of signals
29.
