Abstract
Rats were exposed to broad-band noise (spectral level = 50 dB ± 5 dB between 1000 and 10 000 Hz) for three to five days. Single neurons (N = 60) were sampled in the dorsal and ventral cochlear nucleus. Tuning curves were elevated 30–40 dB re normal [A.R. Møller, Acta Physiol. Scand. 76, 503–512 (1969)]. The slopes of the low-frequency sides of the tuning curves were considerably shallower than normal, thereby making the bandwidth of the tuning curve wider. The inhibitory areas of the tuning curves were either not measurable, or were much more elevated than the excitatory area. Light microscopic analysis of the cochleas revealed no changes in the sensory epithelium.
