Abstract

Functional near-infrared spectroscopy (fNIRS) technique is used to measure concentration of hemodynamic changes (i.e., oxy- and deoxy-hemoglobin) in the human brain, while a subject is performing specific cognitive tasks. The advance brain functions related to music are thought to implicate uniquely human abilities, and it is known to have a strong tendency for hemispheric lateralization in the brain. The purpose of this paper is to investigate the effects of lateralization brain function in auditory cortex using fNIRS for music stimuli with background noise. It was found that the response to music with different background noise will affect different lateralization as indicated in the activation maps.
