Abstract
A cortical sensing device is provided that includes a sensing element and at least one pad attached adjacent to a support member. The pad is substantially thin and made from flexibly-conformable material to accurately and safely place the sensing device upon the brain surface. Contact between the lower surface of the pad and the brain surface anchors the sensing element at a desired position against unintentional movement. The sensing device preferably has three circular pads equidistant from one another. A method to position a cortical sensing device upon a brain surface is also disclosed comprising the steps of providing a cortical sensing device having a sensing element and three dielectric pads attached to a support dielectric member where the member and the pads are thin and flexibly-conformable, placing the sensing device upon the brain surface at a desired position for sensing brain activity, and allowing the pads to conform to the brain surface so that interaction therebetween prevents movement of the sensing element along the brain surface.
