Auditory cortical responses in the cat to sounds that produce spatial illusions

摘要: Humans and cats can localize a sound source accurately if its spectrum is fairly broad flat, as typical of most natural sounds. However, sounds are filtered to reduce the width spectrum, they result in illusions sources that very different from actual locations, particularly up/down front/back dimensions. Such reveal auditory system relies on specific characteristics spectra obtain cues for localization. In cortex cats, temporal firing patterns neurons signal locations broad-band Here we show such spike systematically mislocalize have been passed through narrow-band filter. Both correct incorrect signalled by be predicted quantitatively model spectral processing also predicts localization judgements human listeners. Similar cortical mechanisms, present humans, could underlie spatial perception.
