1. 1. Peripheral and central auditory projections were sectioned and far-field recordings measured to determine neural generators of the waveform in the White Leghorn chick. 2. 2. The mesencephalicus lateralis p. dorsalis and more rostral structures do not contribute to the waveform. 3. 3. Activity of N.VIII is reflected in peaks P1A and P2A; N2A appears to be central in origin but may be in part from the central stump of N.VIII. 4. 4. The crossed dorsal cochlear tract but not the trapezoid body is necessary for P3A and P4A; it is therefore functionally homologous to mammalian trapezoid fibres. 5. 5. P1A, P2A, N2A, P2B are not dependent on crossing fibres.
