Gray Matter Research microdrives are modular, replaceable micromanipulator systems capable of independent bidirectional control of 32, 96, or a larger number of microelectrodes. The systems are designed to be semi-chronically implanted within a GMR recording chamber. Electrode positions are controlled by miniature screw-driven actuators. Electrical contact with the electrodes is achieved through a printed circuit board, allowing wire-free connectivity. When assembled, the system can be implanted for months at a time to permit long-term recordings of neuronal activity. Our microdrives vary by the number of channels and total travel. A diagram of available sizes can be seen here.
