Neuromagnetic Responses to ON/OFF Stimuli of Red Point Light
Information Science Laboratory, NTT Basic Research Laboratories, 3-9-11 Midori-cho, Musashino, Tokyo 180, Japan
This report describes the waveform structures of the magnetic fields produced by the human brain for the ON, luminance increase, and OFF, luminance decrease, responses to the stimuli of a red point light presented to the central and peripheral parts of the retina; These responses are analyzed and described as a function of 1) intensity of luminance, 2) duration of stimulation, 3) position of stimulus in the retina. Results also show that both the magnetic ON and OFF responses are quite similar.
