"\Ye describe the representation of synthetic stopconsonants in a computational model of the mammalian dorsal cochlear nucleus. The speech stimuli have different values of voice-onset time (VOT) and are Iabelied by adult listeners as either /ga/ or /ka/, with a phonetic boundary at 44 ms VOT. The responses of the model's Type IV units to these stimuli also fall into two clear categories with a ...

In contradistinction to the vestibular (Scarpa’s) ganglion, which is located at the level of the internal auditory meatus, the cochlear (spiral) ganglion, the primary sensory ganglion for hearing, is located within the bony confines of the cochlea (1, 2). Multiple cochlear fibers converge to form the cochlear nerve, which courses within the anterior-inferior quadrant of the internal auditory ca...

Neuronal survival in the cochlear nucleus of young animals is regulated by afferent activity. Removal or blockade of nerve VIII input results in the death of 20-40% of neurons in the cochlear nucleus, nucleus magnocellularis (NM), of the 10-14 days posthatch chick. Neuronal death in NM is preceded by complete failure of protein synthesis and degradation of ribosomes. In addition, there is a bip...
