ELECTROENCEPHALOGRAPH

摘要

PROBLEM TO BE SOLVED: To provide an electroencephalograph which allows the electrodes to be positioned easily and accurately.SOLUTION: An electroencephalograph 10 comprises: a belt-like body frame 20 extending from the vertex side toward the left and right ear pinnae when put on the head; brain wave electrodes 35 movable in a longitudinal direction of the body frame 20; and measurement units 52 mounted to the body frame 20 and configured such that the tragi are visible so as to allow the brain wave electrodes 35 to be positioned relative to the vertex. The measurement units 52 have first scales 55 formed to measure the position of the respective tragi, and the body frame 20 has second scales 21 affixed thereto to position the respective brain wave electrodes 35.SELECTED DRAWING: Figure 5
