Gray Matter Research microdrives are modular, replaceable micromanipulator systems capable of independent bidirectional control of up to 220 individual microelectrodes. The systems are designed to be semi-chronically implanted within a GMR recording chamber. Electrode positions are manually controlled by miniature screw-driven actuators. Electrical contact with the electrodes is achieved through a printed circuit board, which avoids the use of wires. The system can be implanted for months at a time to permit long-term recordings of neuronal activity with minimal daily setup time.
