Abstract:
Neurons in the dorsal cochlear nucleus (DCN) of unanesthetized, decerebrate cats can be classified as type II/III (excited at all levels by best-frequency (BF) tones) or type IV (inhibited by moderate and high level BF tones). Many properties of type II/III neurons are consistent with the hypothesis that they are inhibitory interneurons on type IV cells [Young and Brownell, J. Neurophysiol. 39, 282 (1976); Young, J. Acoust. Soc. Am. 63, S76 (A) (1978)]. In order to study functional relationships between these types, pairs of DCN neurons were recorded simultaneously using single microelectrodes. Interleaved spike trains were separated on-line, and each neuron was classified type II/III or IV. For some pairs, complete frequency-intensity response maps were obtained. Cross correlograms of driven activity of type II/III-type IV pairs, obtained using stimuli which excited the type II/III and inhibited the type IV neuron, showed a decrease in the type IV's discharge rate following type II/III firings. This result is consistent with the hypothesis stated above. [Work supported by NIH.]
