ELECTRICAL SENSITIVITY OF THE EYE UNDER THE EFFECT OF THE INTENSE PHOTIC STIMULUS,

Abstract

A study was made of the electrical sensitivity of the eye and the critical frequency of disappearance of a flickering electrical phosphene upon a 15 min. disadaptation with an intensity up to 70 nt and after a short and very bright flash. It has been found that in the former case electrical sensitivity diminishes, while the critical frequency (a measure of functional mobility) increases in the process of subsequent dark adaptation. After short superbright flashes, the changes also go into opposite directions, but they are of a phasic nature. The phenomena are probably a reflection of trace processes in the visual analyzer induced by intensive photic stimuli. (Author)
