Laboratory outline

Tateno/Nishikawa Group

Most of the activity in the brain in control of information processing in the living body has yet to be clarified. At this laboratory, we work on the development of technologies to compensate for the original information of the brain by understanding brain activity and transmitting the brain’s lost information using electronic machinery. Firstly, we measure brain activity at the various hierarchical levels (single cell, cell tissue, and entire brain) of an individual to understand the structure and function of the brain. Secondly, we use microfabrication technology to develop high-performance micro devices that are applied to brain measurement. We particularly use advanced technologies to produce devices to compensate for hearing loss, and explore the expansion of brain functions in acoustic and speech information processing using electronic machinery. Our future goal is to develop innovative technologies in the acoustic information processing field that will be of help in medical care and welfare.

Takahashi Group

From the viewpoint of the welfare engineering for elderly, we conduct research on pressure ulcers (bedsores), a major problem in the aging society. Its pathogenesis is analyzed using the finite element method, a kind of computer simulation, and the physiological effect of force on body tissues is measured based on the laser Doppler method and the ultrasonic Doppler method. We also have developed sensors to measure forces (pressure, shear force, and distortion) that are applied to the skin surface. Other research concerns artificial reality technology to clarify the formation process of human space-time perception in the event of space-time distortion, and we employ the latest magnetoencephalography (MEG) to measure the kinesthetic system and obtain new knowledge of brain function.
