The Harmonic Organization of Auditory Cortex
Harmonicity is a unique feature of human speech, animal vocalizations, music, and many other natural or man-made sounds. Experimental evidence has shown that many neurons in the primary auditory cortex exhibit characteristic responses to harmonically related frequencies, in the form of facilitation and inhibition. Recent neurophysiology and imaging experiments have identified regions of nonprimary auditory cortex in humans and nonhuman primates that have selective responses to harmonic pitches. In this chapter, I propose that a fundamental organizational principle of auditory cortex is based on the harmonic structure of sounds.
