Action potentials from the human cochlea in response to short-tone bursts of different frequencies were recorded by means of a transtympanic needle electrode placed on the promontory. The input-output relations for amplitude (AN1) and peak latency (τN1) of the N1 deflecetion have been studied in a large number of human cochleas and are compared with similar results obtained by round window recording in guinea pigs. The amplitude-intensity relation is qualitatively the same for normal human and guinea pig cochleas. At high stimulus intensities, the peak latencies are the same for human and guinea pig cochleas. At high stimulus intensities, the peak latencies are the same for human and guinea pig cochlear action potentials, but at threshold, the human τN1 is about 3 msec longer than for the guinea pig. In recruiting ears, the input-output relation have been measured for both AN1 and τN1 and compared to those obtained from guinea pig cochleas suffering a high-frequency sensorineural hearing loss.On the basis...
