Abstract

The near-infrared spectroscopy (NIRS) is a noninvasive method, neuroimaging, to be estimating brain activity from the blood flow of cerebral cortex. In this article, we present our two studies about the measurement and evaluation of stress. The one study is to investigate the impact of virtual reality (VR) to brain function in order to measure and evaluate brain activities during viewing the moving image constructed of VR. Six healthy undergraduate students viewed two kinds of VR. Similar part of prefrontal cortex activated during viewing both VR. The other research is to investigate the prefrontal region activation to the stress and emotional stimuli. The International Affective Picture System (LAPS, Lang et al., 1995) was used so as to elicit the three kinds of emotional state of the participants (negative, neutral, positive). Data showed that the sort of emotion activated the different area of prefrontal cortex.
