Abstract :
The age factor is Beheved to have a bearing on man´s abihty to tolerate stress; therefore revealing data on how brain wave activity changes with age is welcome information. A miniature-sized, lightweight, four-channel electrocephalographic system has been developed for the Federal Aviation Agency Medical Service that permits the subject to carry on his normal working activities, completely unhampered in his movements. Recordings can be secured of brain wave activity of a pilot under in-flight conditions where he may be subject to stress, and the EEG studies would assist in evaluating the age-stress relation.
