A chronic multi-electrode microdrive for small animals.
نویسندگان
چکیده
We describe a simple microdrive device appropriate for chronic microelectrode recording in rats. No precision machining is required; all parts are stock or cut from standard stock material with hand tools and assembled with epoxy. The device together with its electrodes can be discarded at the completion of the experiment.

Design and assembly of an ultra-light motorized microdrive for chronic neural recordings in small animals.
The ability to chronically record from populations of neurons in freely behaving animals has proven an invaluable tool for dissecting the function of neural circuits underlying a variety of natural behaviors, including navigation(1) , decision making (2,3), and the generation of complex motor sequences(4,5,6). Advances in precision machining has allowed for the fabrication of light-weight devic...
متن کاملMiniature motorized microdrive and commutator system for chronic neural recording in small animals.
The use of chronically implanted electrodes for neural recordings in small, freely behaving animals poses several unique technical challenges. Because of the need for an extremely lightweight apparatus, chronic recording technology has been limited to manually operated microdrives, despite the advantage of motorized manipulators for positioning electrodes. Here we describe a motorized, miniatur...
متن کاملLarge-scale chronically implantable precision motorized microdrive array for freely behaving animals.
Multiple single-unit recording has become one of the most powerful in vivo electro-physiological techniques for studying neural circuits. The demand has been increasing for small and lightweight chronic recording devices that allow fine adjustments to be made over large numbers of electrodes across multiple brain regions. To achieve this, we developed precision motorized microdrive arrays that ...

The motorized microdrive was designed primarily by Michale Fee. My contributions to the design of the instrument include work on the split connector that allows the motor assembly to be removed from the microdrive barrel, the lateral positioner that provides limited xy positioning of the electrodes, and some of the electrical modifications to the Sutter MP-285 that is used to remotely position ...
