[Vision in the snail: the morphology and electrical activity of the optic nerve].
Light stimulation of a snail's eye elicits spikes in the optic nerve with the latency less by 150-170 ms than that of a corresponding retinal ERG-reaction. This period is constant independently of the intensity of stimulus. Sensory part of the optic nerve consists of at least three types of fibres defining action potentials with different amplitudes and thresholds. Sensory branch of the optic nerve is terminated in the metacerebrum by two separate sets of axon terminals.
