1. An electrode for measuring electrical activity of tissue, the electrode comprising:

  • a sensing electrode having an elongate electrode body forming a partial hollow half cylindrical section having a proximal end, a distal end, and a curved inner surface configured to partially enclose a curved outer surface of the tissue and with;

    i. a penetrating end at the distal end for insertion into the tissue to sense electrical activity of the tissue, andii. a base end at the proximal end that is coupled to an electrical connection wire for communicating the sensed electrical activity away from the sensing electrode; and

    a fixation element that penetrates through an electrode opening in the elongate electrode body into the tissue partially enclosed by the curved inner surface of the partial hollow half cylindrical section of the electrode body to hold the penetrating end of the sensing electrode in position in the tissue.
