摘要：
PROBLEM TO BE SOLVED: To provide a new technique for acquiring brain activity information of a cerebral cortex of a living body. A cortical electroencephalogram electrode in which a plurality of electrodes that can be installed at a plurality of positions in the cerebral cortex are arranged on a deformable substrate is provided with a connector having a plurality of connection terminals electrically connected to a plurality of wirings. Through the first connector portion, the base portion is connected to the first connector portion, one or more electrode portions extending in the first direction, and the wiring portion extending in the first direction, the base portion being connected to the first connector portion, A temporal lobe lower part electrode portion extending in a second direction intersecting the first direction, a base electrode portion connected to the first connector portion and a ground electrode portion for connecting to a ground potential, and a base portion connected to the first connector portion. A reference electrode portion for detecting a reference signal, and at least one end portion of the one or more electrode portions extends in the second direction and is adjacent to the electrode arranged in the temporal lobe lower electrode portion. A temporal lobe upper electrode portion including an electrode that can be arranged is provided.
