Different waveforms of auditory evoked potentials were found when recording from locations in the cochlea, middle ear, and vertex of the skull in the guinea pig. The first negative potentialN1maintained its latency and waveform from a variety of sites, However, theN2potential changed its peak latency and waveform considerably with location. At certain electrode sites, double‐peakedN2waveforms were found. The data suggest that theN2potential is a complex potential reflecting activity from more than one neural population. Thus,N2is composed of repetitive firing of cochlear afferents [Özdamar, Ph.D. dissertation, Northwestern University (1976)] and neurons in the cochlear nucleus or brainstem. The data do not suggest the apical portion of the cochlea as an origin ofN2. TheN2potential was found to be most prominent from the vertex; andN1,N2, andN3appeared at nearly the same amplitudes from certain positions. The potentials maintained their characteristic wave shapes over a range of intensities. [Supported by grants from the NINCDS.]
