Abstract : A low-level exposure to an electron beam has been shown to produce amnesia. Arguments are presented which suggest one mode of CNS activation may have been via visual stimulation. This hypothesis was tested by determining if a photoflash could also produce amnesia using the same task (single trial avoidance). The author shows that a photoflash is an adequate stimulus in amnesia production, and that the extent of amnesia is intensity dependent. Therefore, one possible mechanism of CNS activation by an electron beam may be via visual stimulation. Unknown remain the extent to which other sensory systems may be activated, and the effects of such activation on other CNS functions. (Author)
