STUDIES ON RELATIONSHIPS BETWEEN BRAIN WAVES AND BEHAVIOR

Abstract

An apparatus which presents stimuli to a person when his alpha activity is of a specified phase and amplitude was designed. Using this device, studies have been made on the relationships between human alpha activity and simple visual reaction time. Variations of alpha phase - reaction time relationships in single individuals over the course of time are illustrated. Comparisons of two analyzers are made. The Grey Walter analyzer functions in the frequency domain, and the Burch analyzer in the time domain. The correspondence in data between the resonant circuit and period systems of analysis is high in the alpha range, low in the delta and beta ranges, and negligible above 30 cycles per second. Each system gives specific data lost in the other system. (Author)
