[The humoral link in the mechanism of formation of conditioned food refusal in the edible snail].
Effect was studied of hemolymph of snails-donors with conditioned food refusal, on learning the same habit by snails-recipients. Facilitation was observed of the recipients' learning depending on the quantity of injected hemolymph and the type of conditioned stimulus. The hemolymph of pseudo-conditioned donors inhibited the learning of intact snails-recipients. The possibility is suggested of appearance in the hemolymph of conditioned snails of one or several chemical factors, capable to facilitate elaboration of the same conditioned reflex.
