Abstract: An optrode may provide a cylindrical substrate with two or more electrodes deposited on said cylindrical substrate. The cylindrical substrate and electrodes may be coated by an insulating layer with openings or vias over certain portions of the electrodes that may provide a contact for the neural probe or may be utilized to connect lead lines.
