摘要:
Responses of single auditory‐nerve fibers in anesthetized cat to spoken nasal consonant–vowel syllables were recorded. Analyses in the form of spectrograms and of three‐dimensional spatial‐time and spatial‐frequency plots were made. Among other features, formant transitions are clearly represented in the fibers’ response synchronization properties. During vocalic segments, especially those in /mu/ and /ma/, at a stimulus level near 75 dB SPL, a strong dominance in the responses by frequencies near the second formant (F2) is found for most fibers whose characteristic frequencies (CFs) are at or aboveF2. In contrast, at more moderate levels, the same fibers may show response synchrony to frequencies closer to their own CFs. There are significant differences in the response properties of high and low/medium‐spontaneous‐rate fibers.
