Abstract:
A microprobe system for stereotactic neurotherapy, comprising:a target-determining arrangement for mounting on a patients head, including an adjustable support device, an adapter removably attached to said support device, a manipulator supported by said adapter, a drive unit which is electrically controllable for moving said manipulator based on spatial coordinates (x, y, zâ€”respectively, R, &phgr;) relative to the target determining arrangement, and a manipulator including a probe unit, an exchangeable microfiber electrode mounted on said probe unit in a predetermined orientation and including sensor areas for the sensing of neuronal activity signals, said microfiber electrode being contained in an extendable and retractable telescopic guide tube of variable length and being movable in a controlled manner together with said probe unit in a predetermined direction, said probe unit including an electronic position sensor providing electrode position data displayed simultaneously with neuronal activity signals generated by said microfiber when moving through brain tissue, and means for storing said position data and said neuronal activity signals.
