Serial and parallel processing in rhesus monkey auditory cortex

Auditory cortex on the exposed supratemporal plane in four anesthetized rhesus monkeys was mapped electrophysiologically with both pure‐tone (PT) and broad‐band complex sounds. The mapping confirmed the existence of at least three tonotopic areas. Primary auditory cortex, AI, was then aspirated, and the remainder of the cortex on the supratemporal plane was remapped. PT‐responses in the caudomedial area, CM, were abolished in all animals but one, in which they were restricted to the high‐frequency range. Some CM sites were still responsive to complex stimuli. In contrast to the effects on CM, no significant changes were detectable in the rostral area, R.
