The Responses of Single Units to Simple and Complex Sounds from the Superior Olivary Complex of the Guinea Pig

We have recorded the responses of single units in the superior olivary complex (SOC) of the guinea pig to simple and complex stimuli. We can readily identify the responses of the four principal ascending nuclei as described in other species and we are therefore confident that the guinea pig is a suitable model for studying this region. We found single units in the medial superior olive that represent both diotic iterated rippled noise and dichotic repetition pitch in their temporal discharge patterns. Our data demonstrate a use of the SOC beyond sound-source localisation.
