These electrodes and accessories are designed to permit recording EEG and EMG activity from free-moving animals. The basic components include an electrode pedestal, which can be cemented to the animal's skull, several intracranial electrode assemblies which plug into the pedestal, optional electrical commutators and cabling for connection to the recording equipment. The pedestal holds up to six intracranial, subcutaneous, or electrodes with mounting screws listed in this section. Socket contact terminals and stainless steel screws are offered for those users that want to make custom electrodes. In the simplest configuration, connection is made to the recording equipment via the 6-lead cable which mates with the pedestal, or a commutator can be provided to allow the animal unrestrained movement.

System Components include: Electrode Pedestal, Intracranial Electrodes with Socket, Electrode with Mounting Screw and Socket, Socket Contact, Subcutaneous Electrode with Socket, Dust Cap and 6-lead Connector Cables.
