Color vision in the peripheral retina. II. Hue and saturation. | Hue and saturation of spectral lights were measured (direct scaling) in the fovea and at 45 degrees in the periphery; all lights were of equal photopic retinal illuminance (1200 trolands). At each retinal location both large and small targets were used. As shown by previous studies, small peripheral targets appear desa... | 839,300 | [

The effects of fast neutrons and X rays on the subependymal layer of the rat brain. | Some effects of irradiation of rat brain with single doses of X rays or fast neutrons have been measured.

The gross response to X rays and neutrons was somewhat different, and the results suggest that the... | 841,078 | [
