Abstract

Hair cells in the fish inner ear transduce sound into an electrical signal that is conveyed to the brain via auditory afferents. Fish auditory afferents are broadly tuned to low frequencies, are phase locked, and have monotonic rate-level function. The strength of phase locking decreases along the auditory pathway from the periphery to brain. Frequency tuning is enhanced at the midbrain but no further increase in tuning is found at higher levels of the brain. The peripheral phase locking is transformed into a central code. Octavolateral efferents have distinct response characteristics and regulate afferent inputs to the brain.
