A durable chronic unit recording device with movable microelectrode.
The design of a durable chronic unit recording device with movable microelectrode suitable for cats and monkeys is presented. Sufficiently rugged to remain on cats for weeks during exploration of a single electrode tract, the device also features: choice of stereotaxic coordinates over a large horizontal area at recording time; good stereotaxic precision; capability to hold a single unit for days; excellent insulation between the recording circuit and the animal; and simplicity of design and materials which allows fabrication of numerous devices in one lab.
