[Vision in the edible snail. The morphology and total electrical activity of the retina].
Recording of the integrative electrical activity of the retina of the snail and electron microscopic study of its eye have shown the following. The electrical activity of the photoreceptors is a source of the retinogram (ERG) of the snail. ERG reaction form is characterized by two phases of a response: the initial spike and the following slow fading. For each given value of the photometric brightness of a light signal there exists a low limit of its length, beginning from which the ERG reaction of the snail assumes the form described. The value of the ERG response is a logarithmic function of brightness of the light stimulus.
