Multichannel intracranial recording device using a color imaging brain mapping system

A procedure is described for the manufacture and use of a multichannel (up to 20) intracranial recording device. Electrodes are arranged in a horizontal plane, and can be controlled by a conventional microdrive. Data from multiple channels are visualized and analyzed utilizing a commercially available color imaging brain mapping system. Potential research applications include studies of neural generators of evoked responses through the simultaneous recording of intracranial and scalp potentials.
