Abstract
Single neuronal responses of the kangaroo rat cochlear nuclei to vowel sounds were studied. The vowel sounds used were [aye], [eye], [smcapi], [ɛ], [o], [u] [ɔ], [ə], [æ]. and [ṛ]. Each was approximately 40 msec in duration. Five were linked together to form a 200-msec stimulus. Eighteen combinations of the ten vowels made up the repertoire of stimuli. The results show that the neutral discharge rate to a vowel sound is appreciably changed as a function of where in the stimulus that vowel sound occurs. This vowel positional effect on the discharge is not the same for all neurons. Furthermore, the discharge rate to a particular vowel was greatly affected by the vowels which preceded it. The cytoarchitectonics and responses of cochlear nuclei neurons are related in an attempt to extract neural coding characteristics of this auditory aggregate.
