R2drive S
The R2drive is a recoverable, reusable metal microdrive for silicon-probe implantation, developed in the Buzsáki lab. Weighing under 0.5 g with a footprint below 4×5 mm, it suits rodent work — up to three units can be implanted in a mouse simultaneously. The drive sits on an implantable base that disconnects by removing a screw, so the probe can be recovered and reused across multiple experiments. Probes mounted on R2drives can also connect to a stereotax for acute recordings, making it easy to share a probe between chronic and acute experiments. For chronic implants the system pairs with a protective cap that doubles as a Faraday cage. The S model carries the regular arm — for Neuropixels probes choose the R2drive L.
