Abstract
This study was undertaken to determine how the field potentials recorded from the cochlear nucleus, inferior colliculus, and primary and secondary auditory cortices varied for different modes of frequency and amplitude modulated sound. The sound was presented to anaesthetized animals as a burst of five consecutive modulation envelopes. It had modulation rates which varied from 10- to 80- Hz, and depths of 10%, 50% and 100%. The field potentials were summed over 63 stimulus presentations, and then a spectral analysis was carried out on the result. The evoked responses produced in the various nuclei and by different stimulus parameters were compared using a coherence function.
