THE PRESENT study was part of a series of investigations into the human electroencephalographic response to visual patterns and "pattern sensitivity" at this laboratory^1,2; in particular, the investigations are concerned with -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.⁴

Rémond and associates⁵ first investigated -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 observation^7,8 that each . . . [Full Text PDF of this Article]
