Immunocytochemical methods using an antibody raised against tyrosine hydroxylase (TH) were investigated the distribution of catecholamine-containing neurons in the brain of two
species of crustacean Pagurus middendorffii and Paralithodes camtschaticus. Morphologically different types of TH-immunoreactive neurons are found in the cell clusters
in the protocerebrum, deutocerebrum, and tritocerebrum of divisions the brain in both species studied crustaceans. The similarities and differences in topography, numbers and
morphology of TH-positive neurons in the different structures of the brain in the hermit crab and king crab are discussed.
Key words: catecholamines, tyrosine hydroxylase, crustacea, brain
