Electrode Interface Fixture (EIF)

An Electrode Interface Fixtures (EIF) is two or more leads terminated with electrodes, insulated with a combination of epoxy, silicone, and heat shrink tubing. We implant the electrodes, arrange the leads, and cement the entire apparatus to skull of a laboratory mouse or rat. The EIF8-XAAX-15 provides one ground lead and four signal leads. The ground lead and two of the signal leads are terminated with A-Coils for recording electrocortigogram (ECoG). The other two signal leads are terminated with X-Electrodes for recording local field potential (LFP) in the hippocampus or some other deeper brain region. All EIFs are designed to mate with Head-Mounting Transmitters (HMTs).

There are many versions of the EIF, each with their own part number. There are a variety of leads we can use with the connector, and a variety of electrodes we can deploy on the end of each lead. The EIF Manual lists version and provides links to pictures. Each animal must receive its own EIF. The EIFs are not recyclable.
