Abstract
This invention defines a system for monitoring the brain activity of a human patient under anesthesia in order to determine the patient's level of consciousness. The system uses a plurality of receptors which are mounted in predetermined anatomical positions on the patient's head. The receptors are secured by adhesive foam patches. The appliance fits snugly to the head with the aid of self-adjusting strip that carry imbedded electrical circuitry for the receptors. Electrical connectivity in locations where scalp hair is most likely to be present is improved by the use of braille-tip electrodes fitted with large gel reservoirs.
