R2drive L

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 L model carries the larger Neuropixels arm — for standard silicon probes choose the R2drive S.
