Properties of a catecholaminergic system in some coelenterates. A histochemical and autoradiographic study

Properties of a catecholaminergic nervous system in a coelenterate nervous system are described. The catecholamine present shows similarities to noradrenalin but it is not identical with noradrenalin. Contrary to known vertebrate catecholaminergic systems, neither a reuptake system nor a degrading system is present in the coelenterate catecholaminergic nervous system.
