Nervous and photochemincal components in visual adaptation
article
From experiments in which the influence of stimulus-area on the chance of observation of light flashes was studied it is concluded that the number of quanta which have to be effectively absorbed by the retinal receptors in order to produce a light sensation, which has been proved to be 2 for the dark-adapted eye, increases with the progress of light-adaptation. This fact indicates the presence of a nervous component in addition to the photochemical component in the mechanism of adaptation.
