[The structural organization of the snail sensory systems].
In the paper are reviewed the author's data on the structure of peripheral nervous system of the body wall, gravitational organs--statocysts, eyes, and organs of distant chemoreception--ommatophors, or posterior head tentacles, of the snails Helix vulgaris and Helix pomatia. Localization in the CNS of central parts of the main sensory systems is shown and some structural characteristics of them are described. The data on the organization of the procerebrum which takes part in processing of information from the receptors of the head tentacles are presented. By some morphological features the procerebrum may be considered as one of the highest associative centers of the snails. The data under consideration were obtained by means of silver impregnation by Golgi, retro- and anterograde infusion of CoCl2, horseradish peroxidase and Lucifer yellow into the nerves, as well as by means of a number of other classical histological techniques.
