[A floating hydraulic micromanipulator for microelectrode research on brain neurons].

The article describes a simple floating hydraulic micromanipulator of original construction which works in positive-positive pressure and provides maximum stability of the microelectrode tip concerning the neuron in the moving brain. This work is achieved by fixing of the micromanipulator on the hinged suspension bracket and by setting of it on the surface of the object with the help of bearing site. Breathing and vascular brain moving don't influence the neuron activity lead.
