Measurement of human brain function by fMRI, fNIRS and EEG
figure

My research is to measure and analyse human brain activity related to sleep, social communication, learning, and psychotherapies in order to elucidate the mechanism of human brain using fMRI, fNIRS and EEG.

Also, to make fNIRS measurement highly precise and reliabile in various living environments, I am conducting the development and validation of methods to remove artifacts by skin blood flow and movement of probes and extract brain activity from fNIRS data.
