abstract：:The nitric oxide (NO)-cGMP signaling system and cAMP system play critical roles in the formation of multiple-trial induced, protein synthesis-dependent long-term memory (LTM) in many vertebrates and invertebrates. The relationship between the NO-cGMP system and cAMP system, however, remains controversial. In honey bee...

abstract：:Delta9-THC and synthetic cannabinoids produce memory impairment in humans as well as in laboratory animals. The high concentration of cannabinoid CB1 receptors and the presence of endocannabinoids in the hippocampus suggest that a cannabinoid neurochemical system may play a role in learning and memory processes. Thus,...
