[Effective stimulation of Turkestan catfish electroreceptors].

In Turkestan catfish (Clyptosternum reticulatum) passive electrical properties of the skin, the structure of electrical field near and within the fish as well as single nerve fibre impulse activity of electroreceptors, were studied. The resistance and capacity of the skin were 18-25 kOhm.cm2 and 1 micro F/cm2, resp. The effective stimulus for the electroreceptors involved the voltage drop across the skin. The significance of the skin electrical properties for functional characteristics of electroreceptors is discussed.
