Abstract In this article, we evaluated the electrophysiological performance of a novel,
high-complexity silicon probe array. This brain-implantable probe implements a dynamically
reconfigurable voltage-recording device, coordinating large numbers of electronically
switchable recording sites, referred to as electronic depth control (EDC). Our results
show the potential of the EDC devices to record good-quality local field potentials,
and single- and multiple-unit activities in cortical regions during pharmacologically
induced cortical slow wave activity in an animal model.
