title: The vision of the snail: the spectral sensitivity of the dark-adapted eye.
abstract: The spectral sensitivity of the dark-adapted eye of the snail Helix lucorum L. was investigated in semi-intact "optic cupoptic nerve-cerebral ganglion" preparations. The data of the recording of the electroretinogram in response to monochromatic radiation of varied intensities were used to plot the spectral sensitivity functions. The averaged spectral sensitivity function is well described by a Dartnall nomogram for the photopigment rhodopsin with a sensitivity peak at 496 nm.
