Abstract:
1. A living body information signal processing system combining a living body optical measurement apparatus and a brain wave measurement apparatus comprising: the living body optical measurement apparatus in which light of from visible to near infrared is irradiated from a first position on a head portion of a subject via an irradiation use optical fiber and the penetration light is received at a second position on the head portion of the subject via a light receiving use optical fiber and which measures based on the received penetration light an optical characteristic variation induced by a brain activity inside the head portion of the subject at a measurement position corresponding to an intermediate position between the first and second positions as a living body optical signal corresponding to the measurement position; the brain wave measurement apparatus which measures an electrical characteristic variation induced by a brain activity inside the head portion of the subject through a brain wave electrode configured to be attached to a third position representing a measurement position on the head portion of the subject as a brain wave signal corresponding to the measurement position; a probe device for the living body optical measurement apparatus and the brain wave measurement apparatus which carries top end portions of the irradiation use optical fiber and the light receiving use optical fiber and the brain wave electrode and is configured to be mounted on the subject; and a living body information signal processing and displaying device which displays the living body optical signal corresponding to respective measurement positions from the living body optical measurement apparatus and the brain wave signal corresponding to respective measurement positions from the brain wave measurement apparatus on a common display device while correlating the respective measurement positions each other.
