Rapid classical conditioning of odor response in a physiological model for olfactory research, the tiger salamander.

abstract：:Electrophysiological responses of olfactory receptor neurons in both male and female silkmoths (Bombyx mori) were investigated. In both sexes, the G-protein activator sodium fluoride and 1,2-dioctanoyl-sn-glycerol, a membrane-permeable analog of the protein kinase C activator diacylglycerol, elicited nerve impulse res...

However, some natural populations of B. germanica have been found that are behaviorally deterred from eating glucose. In dose-response studies, glucose was a powerful phagostimulant for wild-type cockroaches, but...
