[Mechanisms of achromatic vision in snail Helix lucorum L.: intracellular study of light-sensitive cells in retina].

[Article in Russian]


Intracellular study of the eye of land snail Helix lucorum L. demonstrated two types of visual cells responding to flashes of white light by slow sustained depolarization (D - type) and by slow sustained hyperpolarization (H - type). Peaks of spectral sensitivity of both types at 465-500 nm coincide with the peak of spectral sensitivity of photopigment 'rhodopsin'. The revealed D- and H - cells in the snail retina are considered as analogous of B- and D - cells, respectively, in the vertebrate visual system.
