Abstract

The purpose of this research was to explore the mechanisms of how the brain is able to distinguish harmony and dissonance. The understanding of how sound is converted to neural messages began with Békésy, who discovered how sound is transduced in the cochlea. Later it was found that each auditory neural fiber, which carried the messages for a specific frequency of sound, corresponded to a specific place in the primary auditory cortex (referred to as “tonotopic”). In this experiment, the neural activity of the auditory cortex (T4) and of the sensory cortex (CZ) was recorded in response to specific auditory stimuli using electroencephalography.
