Abstract

Based on the results of previous behavioral experiments, researchers believe that sensitivity to light stimuli is not restricted to the eyes in the pond snail Lymnaea stagnalis. To determine the presence of a non-ocular dermal photoreception system and to examine the synaptic connections between this peripheral system and the central nervous system, we electrophysiologically examined the activities of the pedal nerves in L. stagnalis by light stimulation. The results demonstrated that light stimulation evokes non-ocular dermal photosensitive responses in the foot, that these responses exert inhibitory, afferent influences through the inferior pedal nerves to the pedal ganglia, and that these responses were independent of the ocular photoreception system in L. stagnalis.
