Abstract: Auditory neural response and stimulated neural potentials were observed in rats and chickens with the help of microelectrode surgically implanted in the scala tympani which filled with perilymph. Response patterns were recorded from both animals properly recovered from the effects of proper anesthesia. In rats the cochlear auditory neurons showed a thin band and spikes with high amplitude at a frequency about 300 Hz. In chicken the peak was 15-20 dB higher in amplitude than the stimulated cochlea above the constant frequency of amplitude peaks. In rat the amplitude of peak was 8-12 dB higher in amplitude but it was very obvious because a clear null in a narrow band of constant frequencies just bottom of the peaks. The amplitude and the sharp null in peaks in both animals were markedly altered by level of anesthesia so their response patterns were somewhat different over all stimulating frequencies.
