Elastic electrode holder for brain mapping

The utility model relates to an elastic electroencephalogram electrode cover, which comprises longitude lines, latitude lines and a lacing, wherein twos ends of a plurality of the latitude lines are respectively converged on two end points, one end of the lacing is connected with the end point of the latitude lines, the longitude lines are perpendicularly cross with the latitude lines, and are fixedly connected with two side lines and an intermediate line in a plurality of the latitude lines. When using the elastic electroencephalogram electrode cover, an elastic electrode cap is placed on the head portion of a detected person, and a gauze mandible pad is arranged on the mandible, and then is tied tightly, wherein the gauze mandible pad is a multi-layer gauze bag, and is separated from the electrode cap, and electrodes can be fixed after appropriately adjusting the positions of lines on a head cap. The elastic electroencephalogram electrode sleeve of the utility model simplifies the operation procedures, has
