　We arestudying about perception mechanisms of humans, mainly audition, using various techniques; non-invasive neurophysiological measurements like MEG, EEG and other electrophysiological recordings, psychological measurements, physical measurements, and numerical simulations. Further, I am applying knowledge and information obtained in the basic research on the perception mechanisms to developments of medical and welfare devices, optimization of audio-visual environments, and evaluation and "sound design" of sound noises.

Current main themes:

Elucidation of mechanisms of sensation/perception/cognition of humans using noinvasive measurements and its applications to optimization of the living space

Measurements of brain activities using MEG, EEG, and fMRI
Optimal design of visual and auditory environment using psychological and neurophysiological data
Developments of brain-machine interface techniques
Developments of data analysis techniques for MEG and EEG

MEG measurement (Collaboration with AIST and Univ. of Tokyo)

Psychological experiments

Application for the brain-machine interface

Elucidation of neurophysiological/psychological/physioacoustical mechanisms of bone-conduction perception and its applications to welfare devices

Study on the neurophysiological mechanism and psychoacoustical/physiologoical characteristics of bone-conduction perception, including bone-conducted uitrasonic (BCU) perception and pinna-conduction perception in human
Development of bone-conducted ultrasonic hearing aid (BCUHA) for the profoundly hearing impaired
Development of pinna-conduction smartphone
Developments of other welfare and medical equipments using bone-conduction technique
