title: [An experimental unit for the recording of the escape reaction of a ground snail to tactile stimulation].
abstract: An original working experimental unit for noninvasive objective recording of the magnitude of escape reaction of a ground snail evoked by tactile stimulation is described. A. snail creeps upwards over the cylinder rotating around its horizontal axis. A watching device ensures a constant snail position relative to a light source and a photoelement. A device for tactile stimulation which provides graduated energy of an impact is constructed on the basis of the magnetic circuit of a loudspeaker. In response to a tactile stimulus a snail pulls in its feelers, head, and foot, and the area of snail's shadow decreases. These changes are indicated by the photoelement.
