Abstract: An electrode assembly adapted to be attached to the skin over selected facial muscle groups picks up signals to be analyzed by an anesthesia adequacy monitor that measures the level of awareness of a living animal, typically a human being. The electrode assembly also includes a stimulator that stimulates a facial nerve to determine the level of paralysis, or neuro muscular block, of the facial muscles. Also disclosed is a method of manufacturing the electrode assembly by printing a pattern of electrically conductive material through a silk-screen or an ink type process onto a flexible layer, and then coating the result with a non-conducting adhesive except at points corresponding to sensing points for the desired muscle groups. Finally, a method for using such sensing and stimulating devices is shown in determining and maintaining an appropriate level of patient awareness, muscle paralysis, and analgesia under anesthesia.

Abstract: A method and apparatus for mediating a biofeedback session with a human subject in which measurements of electrophysiological quantities are used to control the presentation to the subject of a series of prestored audio-visual sequences of varying levels of clarity resident on a direct-access video storage device. The sequences are real scenes designed to induce a desired psychological state when viewed. As the subject succeeds in altering his physiological parameters, the clarity of the presented image and sound improve as an indication of success. By using the invention, the subject develops a conditioned response to the scenes and is able to control his physiological parameters even when away from the apparatus by remembering the audio-visual sequences used during treatment.
