[Peripheral control of the feeding behavior of fresh water mollusks].

Appetitive and consummatory feeding behavior was shown to be initiated by stimulation of different loci. Feeding programs were different in their motor output frequency in P. corneus and L. stagnalis stagnalis. The maintenance of the feeding program was provided by sensory input. In contrast to the insect flight generator, the feeding neuronal program had no peripheral regulation system in freshwater snails, its feeding program being more autonomic from peripheral influences than the flight motor program in insects.
