The author's data on the structural organization of the nervous system of the body wall, the gravitational organs (the statocysts, the eyes, and the chemosensory organs), and the head tentacles of the snailsHelix vulgaris andHelix pomatia are correlated in this paper. The localization in the CNS and some structural characteristics of the central divisions of the sensory systems are shown. Information is presented on the structure of the procerebrum, an associative center participating in the processing of chemosensory information. The data were obtained using the Golgi method, the retro- and anterograde transport of CoCl2, horseradish peroxidase, and lucifer yellow, as well as a number of other classical histological methods.
