Vestibular hair cells and afferents: two channels for head motion signals
RA Eatock, JE Songer - Annual review of neuroscience, 2011 - annualreviews.org
Vestibular epithelia of the inner ear detect head motions over a wide range of amplitudes
and frequencies. In mammals, afferent nerve fibers from central and peripheral zones of
vestibular epithelia form distinct populations with different response dynamics and spike
timing. Central-zone afferents are large, fast conduits for phasic signals encoded in irregular
spike trains. The finer afferents from peripheral zones conduct more slowly and encode
more tonic, linear signals in highly regular spike trains. The hair cells are also of two types, I …
