<P>PROBLEM TO BE SOLVED: To restrain generation of RF noise by transmitting an electric signal introduced into a magnetic shield room as a light signal by an optical fiber in an electric stimulus device used in the magnetic shield room. <P>SOLUTION: In this electric stimulus device, a plus stimulus electrode and a minus electrode are brought into contact with a part of an organism to apply electric stimulus to the organism, thereby testing the reaction of nerve and brain. An insulated photo diode array is put in the connecting state between the plus electrode and the minus electrode, and an optical pulse signal enters the photo diode array through the optical fiber. <P>COPYRIGHT: (C)2003,JPO |
