Spontaneous Activity In The Eighth Cranial Nerve of The Cat

Abstract
Spontaneous discharges of single units in the eighth cranial nerve of anesthetized cats were recorded with micropipets and studied by means of interspike-interval histograms. The histograms for units in the auditory branch generally have modes less than 10 msec, high skew and high coefficients of variation (CV). The histograms for units in the superior division of the vestibular branch generally have modes longer than 10 msec but have either low skew and low CV, low skew and high CV, or high skew and low CV. Units with high and low skews are found in almost equal numbers in the anterior portion of the superior division, whereas an overwhelming proportion of the units in the posterior portion have low skew.
