Abstract

Electroencephalography (EEG) is the study of the brain’s electrical activity. It has been used extensively as a research tool as well as in clinical settings. When sensory stimuli are presented and EEG is recorded electrical potential is evoked. The most widely studied of these evoked potentials is called the P300–a large positive wave that occurs about 300 milliseconds after the stimulus is presented. A P300 can be elicited and recorded using any sensory modality. A similar evoked potential is the N450 which occurs about 150 milliseconds after the P300 and is negative in amplitude. Our experiment examined the effect of harmony and dissonance in two tones on these evoked potentials.
