On The Place Of Photic Adaptation


, : On The Place Of Photic Adaptation. Journal of General Physiology 11(3): 289-295

The progress of photic adaptation of Agriolimax, when studied by the method of compounding phototropic and geotropic vectors, is shown to be uninfluenced by the concurrent gravitational excitation. Direct proof is thus obtained that the adaptation to light, manifest in its steadily decreasing effectiveness as a stimulus during the course of exposure, is not due to any central nervous adjustment simulating "learning," but is due to photochemical changes in the receptors.
