Abstract
Nitric oxide, produced by nitric oxide synthase in brain tissue, is essential for several different kinds of learning in vertebrates. We present the first evidence that it is also essential for learning in an invertebrate. Intramuscular injections of an inhibitor of the enzyme completely block touch learning in Octopus vulgaris. Eight control animals learned a touch paradigm, but none of eight synthase-inhibited ones learned it.Keywords
