Electrophysiological analysis system for detecting pathology, has crenels covering range of voltage that causes appearance and disappearance of electrochemical phenomenon at neighborhood active electrodes from one crenel to other crenel

摘要

The system has an electronic commutation circuit (30) for selectively connecting a pair of activated electrodes (E1-E6) to an adjustable direct voltage source (21). Measuring circuits (22, 40) relieve data that represents a current in the active electrodes and potential on certain electrode in response to an application of crenels. A range of voltage covered by crenels causes appearance and disappearance of an electrochemical phenomenon at neighborhood active electrodes from one crenel to other crenel.
