(Click to see larger image) Narishige's MO-97A is an oil hydraulic micromanipulator meant to be mounted on the skull of a medium-sized animal such as monkeys to perform chronic experiments. Its 30mm fine movement range permits deeper brain insertion of a microelectrode. The MO-97A allows a separately available guide tube to be fitted for precise positioning and insertion of a microelectrode into hard tissue or deep brain cells. Despite these added features, the drive unit has reduced its weight to lighten the burden on the animal.

     Its open-type stage permits visual observation of the microelectrode insertion while operating the X- and Y- axis control knobs, and also permits multi-channel operation as well as the use of microelectrodes of various types. The remotely controlled oil hydraulic system permits vibration-free insertion of a microelectrode. With the detachable/attachable drive unit fixed on the skull mount chamber, even if the animal head moves, the microelectrode can be held in position.



*With the drive unit detachable from the chamber, the MO-97A permits the use of chambers of various shapes. Consult us for details.
*Used in combination with a pulse motor microdrive, this system permits even more accurate operation.
