Abstract

This paper presents our empirical results by using 32 channel NIRS system to examine the changes in oxygenation in regions of prefrontal cortex. Four healthy subjects participated in the experiment by performing various cognitive tasks such as mathematical, imaginary and computer game. The concentration levels in oxyHb and deoxyHb varied depending on subject's mental workload as a result we could locate strong brain activation regions. We analyzed hemoglobin concentrations in wavelet domain to detect and extract the true brain stimulus from noisy NIRS measurements.
