The present invention provides systems, methods and devices for sensing electrical activity in the brain of a mammal. Some aspects include a set of cortical electrodes configured, in use, to detect electrical activity on the surface of a brain, the assembly comprising: a ring-shaped substrate; and a plurality of electrical sensors attached to the ring-shaped substrate, the plurality of electrical sensors being spaced along the ring-shaped substrate to form a ring of electrical sensors substantially encircling an opening formed by the substrate. ring shape. |
