| Abstract | The BOLD response in the inferior colliculus (IC) was stronger to the forward than to the inverted vocalizations despite their identical frequency spectrum, clearly demonstrating response selectivity. The selectivity was prominent in the external cortex of IC, but was not observed in the lateral lemniscus (LL). The response selectivity was nearly abolished following atropine injection. The results suggest that the auditory midbrain is the first place in the ascending auditory pathway to display response selectivity to vocalizations, and highlights the ability of fMRI in investigating the processing of behaviorally relevant sounds. |
