abstract：:1. We have stimulated responses of stellate cells in the anteroventral cochlear nucleus (AVCN) to single-formant stimuli (SFSs) with the use of recorded auditory-nerve fiber (ANF) responses as inputs. In particular, two important features of temporal discharge patterns, the phase locking to best frequency (BF) tones a...
