[Role of the body of the skate in initial processing of electroreceptor system signals].

Possible space mechanisms of information conversion processes with Lorenzinian ampullary apparatus during detection of the dipole electric field were studied using mathematical modelling methods. The stationary voltage distribution in the nonuniform media was calculated by numerical methods. The skate body was simulated by a thin disk. If the dipole axis lay in the disk plane potential distortions near the disk were negligibly small. In other cases the electrical field energy absorbed by ampullary groups was dramatically reduced. It is supposed that body tissues serve as a space filter of the electroreceptive system.
