Patent ID: 7774053

Claim:
A neural probe array for subdural implantation to record intracranial field potentials in a brain, comprising: a base having first and second sides and a plurality of apertures extending therebetween, each aperture extending along a corresponding axis and having a first end communicating with the first side of the base and a second end communicating with a second side of the base; a plurality of contacts laterally spaced from each axis along which the plurality of apertures extend and being positioned along the first side of the base for recording the field potentials, the contacts: having terminal ends co-planar with the first side of the base so as to allow the terminal ends of the contacts to be positioned adjacent target neurons in the brain; and being arranged in a generally rectangular pattern for engagement with the brain; and a plurality of conductors, each conductor having a first end operatively connected to a corresponding one of the plurality of contacts and a second opposite end; wherein: the first side of the base is in fluid communication with the second side of the base via the plurality of apertures; and the base is free of active electronic components mounted thereto.
