Multi-electrode recording system for the study of spatio-temporal activity patterns of neurons in the central nervous system.
A new type of recording microelectrode with mechanical and electrical properties suitable for use in microelectrode assemblies for neurophysiological studies in the central nervous system was developed by adaptation of principles from optical fiber technology. A microdrive for independent positioning of up to 7 electrodes for the recording of electrical activity from individual neurons was constructed. It operates by the combined action of a stepping motor and a system of independently controllable piezoelectric clutches and brakes for each electrode.
