Dopamine in the lobster Homarus gammarus. I. Comparative analysis of dopamine and tyrosine hydroxylase immunoreactivites in the nervous system of the juvenile
Abstract As a catecholamine, depamine belogs to a class of molecules that have multiple transmitter and hhormonal functions in vertebrate and invertebrate nervous systems. However, in the lobster, where many central beurons have been identified and the peripheral innervation pattern is well known, t...
