Tracing neural pathways in snail olfaction: From the tip of the tentacles to the brain and beyond
The anatomical organization of the olfactory system of terrestrial snails and slugs is described in this paper, primarily on the basis of experiments using the African snail Achatina fulica.… Expand
Determinants of paternity in the garden snail Helix aspersa
Abstract. Despite the likely importance of post-copulatory sexual selection in simultaneous hermaphrodites, the factors influencing sperm competition in these organisms are generally unknown. We have… Expand
Dart receipt promotes sperm storage in the garden snail Helix aspersa
Abstract. During courtship, many helicid snails attempt to pierce the body walls of their mating partners with mucus-coated calcareous darts. The mucus covering the dart induces conformational… Expand

- 1 November 1986
Evidence is presented indicating that the mesocerebrum of the terrestrial snail, Helix aspersa, has a major role in the control of sexual behavior. Morphological and physiological results demonstrate… Expand
Tentacular function in snail olfactory orientation
Summary1.The olfactory orienting behavior of the terrestrial snailAchatina fulica was studied in intact animals, in animals with bilateral lesions of either the anterior tentacles or the posterior… Expand
Corticofugal influence on activity of lateral geniculate neurons in the cat.
This invention relates to a novel method for enhancing zinc serum and tissue concentrations which comprises administering a compound of the formula: wherein Z is C=C, O, S, NH; R is hydrogen, methyl,… Expand
Changes in the reproductive system of the snail Helix aspersa caused by mucus from the love dart.
The function of the love dart in certain species of terrestrial snails is unknown. In Helix aspersa, the dart is a sharp calcareous structure that is used to pierce the partner's skin during… Expand
Morphology of interneurons in the procerebrum of the snail Helix aspersa
Terrestrial snails have a highly developed sense of olfaction. Because the procerebrum has a large number of cells and is located at the entry site of the olfactory nerve into the brain, the… Expand
