THE PRESENT study was part of a series of investigations into the human electroencephalographic response to visual patterns and "pattern sensitivity" at this laboratory1,2; in particular, the investigations are concerned with λ-waves,3 which occur as a response to scanning of patterned visual fields in the electroencephalograms of normal human subjects and which also have been found in many varieties of animals.4Rémond and associates5 first investigated λ-waves, using a computer-averaging technique. They called the response obtained the "lambda complex." In the parieto-occipital region, it consisted of four main components. The first was negative (N1), followed by a positive wave (P1), and then by a negative (N2) and a positive deflection (P2). In the present investigation, briefly reported6 previously, a slightly different technique, using the Computer of Average Transients (CAT), was employed. The method was based on the observation7,8 that each |
