Caption: Snail brain. Three-dimensional computer graphic of a snail brain showing neurosecretions, in a study on the effect of light on snail biorhythms. Colour variations (yellow, red, white) show varying levels of neurosecretion. This research is conduc- ted by B. Buisson and A. Blanc at the Laboratory of Applied Animal Biology in St. Etienne, France. They have shown that garden snail biorhythms are under the influence of light. Snails rest by day and are active at night. Light acts on the snail eye retina which affects brain neurosecretions over a 24 hour period. These neurosecretions pass from the brain at night to nerves in the morning, reaching muscles by day causing the snail to rest.
