Research Overview

All around us are human interactive digital device, which control by operator movement. In order to operate such devices, we must familiarize oneself with the function and location of all the controls and indicators. This is a typical example of humans stylize into a device fashion. Ideally, humans should be the master and the device the servant. Today, however, the shoe is on the other foot. In my laboratory, we are thinking again the relationship between devices and humans by researching ways to stylize ‘devices to humans’ with neuro-engineering technology. To construct a humancomputer interface, measures brain activity (neural code), analyzing the neural code by information theory, and control a device suitably based on the information. We are currently carrying out the following research:

  1. Development of a brain-computer interface based on multidimensional-neural activity measurements. We are aiming to obtain and analyze multi-faceted and multidimensional information on biological responses to phenomena, including the brain’snerve cell activity, and construct a system that can be controlled by more accurately transmitting human thoughts to a computer.
  2. Development of electrodes that effectively stimulate central nerve systems and monitoring neural activity. We are aiming to construct an artifi cial nerve in which information can be eff ectively communicated by directly transmitting messages from a computer to central nerve system.
