Distribuzione e analisi funzionale dei neuromodulatori in Octopus vulgaris

ments the pattern of distribution of biogenic amines in the brain of the cephalopod mollusc Octopus vulgaris. The data show that dopamine, noradrenaline and octopamine are not ubiquitary in the brain, as considered before, and that a division of labour between visual and tactile processing system exists. These data largely revise previous available knowledge and for the firt time depict the distribution of octopamine in the brain of the octopus. This despite this molecule has been for the first time discovered in the salivary gland of this animal more than 100 years ago.
