Meeting Abstract 45.5  Tuesday, Jan. 5  The shadow response of RPeD11, in Lymnaea SUNADA, Hiroshi; SAKAKIBARA, Manabu*; Tokai University manabu@tokai.ac.jp Stress, especially that elicited by ecologically relevant stressors (e.g. Predator detection) enhances long-term memory (LTM) formation in the pond snail, Lymnaea stagnalis. In addition, predator detection elicits a suite of so-called vigilance behaviors one of which is […]

Meeting Abstract 45.3  Tuesday, Jan. 5  Dermal photoreception in the pond snail Lymnaea PANKEY, M.S.*; SUNADA, H.; SAKAKIBARA, M.; University of California, Santa Barbara; Tokai University; Tokai University mpankey@lifesci.ucsb.edu Light perception in many animals, even those lacking eyes, is assisted by a diffuse system of photoreceptive neurons. Such nonvisual photoreception may represent an ancient mechanism predating the […]
