The influx of tryptamine into snail (Helix pomatia) ganglia: comparison with 5-hydroxytryptamine [0.03%]
墨角螺(Helix pomatia)神经节中的5-羟色胺和三氟角碱的摄取作用的比较研究

Extraocular photosensitivity in Aplysia fasciata was studied in the skin and in the central nervous system (CNS). Local illumination causes contractions of the muscles of the body wall, which are obviously mediated by the peripheral nervous...
Microelectrode investigations of learning phenomena in snail (Helix pomatia) neurones [0.03%]
