MEASURING APPARATUS FOR ELECTRIC POTENTIAL INDUCED BY CEREBRUM

摘要

PROBLEM TO BE SOLVED: To measure overall induced electric potentials of somatic-sensation, visual-sensation and auditory-sensation with reducing inflection of psychosomatic conditions of a subject. ;SOLUTION: A measuring apparatus has; a measuring means 1 for somatic- sensation induced electric potential to measure electric potential, induced in cerebrum by giving electrostimulation to human body; a measuring means 2 for visual-sensation induced electric potential to measure electric potential induced in cerebrum by giving stimulation to eyesight; a measuring means 3 for auditory-sensation induced electric potential to measure electric potential induced in cerebrum by giving stimulation to audition; and a timer 4 transmittable trigger-signals to determine the timing of when to give stimulation to a human body. Electric potential induced in cerebrum is measured in a sequence of and by the measuring means 1, 2 and 3 being triggered by the trigger-signals inputted from the timer 4.;COPYRIGHT: (C)1998,JPO
