[The rhythmicity of physiologic changes in the functional state of the visual and skin temperature analyzers in man].
Considering significance of the light and the temperature factors for the rhythmic activity of the organism, the maximum of the day's functional activity of the thermoreceptor system was noted at 5 p.m. and the minimum--at 1 a.m. The functional activity of the visual receptor system is closely related to the day's changes in illumination. Seasonal changes of activity of the sensory systems under study are also obvious. The functional adjustment of each analyser and their coadjustment are emphasized as very significant.
