EEG ELECTRODES FOR IN-FLIGHT MONITORING.

An electrode for in-flight recording of EEG is described. This electrode provides significant improvement over previously available types. When properly applied, it produces little noise, even when tapped. It is difficult to accidentally dislodge and is comfortable under close-fitting head gear. The leads, a major problem source, may be replaced easily. The impedance between two electrodes is 5000 ohms or less, permitting use with miniature transistorized amplifiers. [ABSTRACT FROM AUTHOR]
