<P>PROBLEM TO BE SOLVED: To efficiently examine a plurality of examinees by saving a preparation period from mounting electrodes to starting the examination required for every examinee. <P>SOLUTION: This brain function determination system 1 is provided with a plurality of brain wave signal detection means 3 each disposed in contact with the scalp and at least having a detection part 2 detecting the brain wave signal S1; a brain function determination means 7 determining the brain function state based on the brain wave signal S1 detected by the brain wave signal detecting means 3; a contact state determination means 4 determining a contact state between the detection part 2 in each brain wave signal detection means 3 and the scalp; and a changeover means 5 selecting the brain wave signal S1 from the brain wave signal detecting means 3 which is determined by the contact state determination means 4 to be favorable contact state and outputting it to the brain function determination means 7. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
