[The mapping of the neurons that participate in the innervation of the body wall of the edible snail].

In the paper are presented the results of the experiments with the retrograde staining of the left-side cutaneous nerves of the pedal ganglia of the snail Helix lucorum. The somata of neurons which sent processes forming the studied nerves were revealed with the help of nickel and cobalt ions precipitation by the rubeanic acid. A lot of nerve cells including some command neurons were found in all the ganglia excluding the buccal ones. Especially large amount of neurons was stained in the ipsilateral pedal, pleural, and parietal ganglia.
