[The Cerebral Function Monitor. Description, functioning and interpretation principles].

The Monitor of Cerebral Function enables continuous monitoring of the cerebral electrical activity and this over long periods due to the slow recording speeds. The cerebral electrical signals picked up by the electrodes attached to the scalp are registered in the form of a curve which fluctuates to a greater or lesser extent depending on the recording speed. The examination of the height of the curve with respect to zero and its amplitude indicates the voltage of the cerebral activity and yields information regarding polymorphism. It is thus possible to monitor variations in cerebral activity over a prolonged period during anaesthesia as well as during the revival phase with the Monitor of Cerebral Function, the electroencephalogram being reserved as an aid to precise diagnosis and for localization and close scruting of the anomalies.
