The critical frequency of flicker fusion in the central and four peripheral points of the retina was investigated in 12 test subjects during and after one hour exposure to wide-band noise of 95 dBA. The subjects showed two types of response: three displayed an increase and nine a decrease of the flicker fusion critical frequency as compared to the control(More)
The effect of long-wave ultraviolet radiation on higher nervous activity was studied in mice. Irradiation with suberythema doses was found to have a beneficial effect on the rate of formation of a conditioned defensive active avoidance reflex. Of two schemes of irradiation tested—with constant and with gradually increasing doses—the latter proved to be more(More)
Light sensitivity of the central and peripheral parts of the human retina has been studied in an hour exposure to broadband noise of 95 dBA intensity and in an after-effect period. The indices of time threshold of dark adaptation and the visual acuity restoration time at reduced brightness were analysed. Four types of response to acoustic stimulus have been(More)
Photosensitivity of the retina is one of the most labile parameters of visual function relative to various factors including noise. Data in the literature on the action of noise on photosensitivity of the eye are few in number and contradictory in nature. Some workers [6, 7] observed an increase in photosensitivity during exposure to an acoustic stimulus,(More)
