Recording Chamber Drawings J. S. Pezaris Computation and Neural Systems California Institute of Technology, Pasadena, CA 91125, U.S.A. Abstract This paper contains the mechanical drawings used for the recording chambers used in the Andersen Lab. The chambers are designed specifically for the FHC microdrives, but are adaptable to Narishige microdrives. Included are chamber, plug, and removal tool drawings, sufficient for any machine shop to recreate the devices used.
