Abstract

Current source density and multiunit activity elicited by stop consonant-vowel syllables were examined in primary auditory cortex of an awake monkey. Relative amplitudes of the speech-evoked responses were determined by the onset spectra of the consonants and the tonotopic organization. This finding supports the psychoacoustic hypothesis that the onset spectra of stop consonants are important determinants for the discrimination of place of articulation.
