Summary As part of a follow-up study to our previous investigation of the catecholaminergic neurosecretory cells in the brain of adult female locusts (Locusta migratoria migratorioides) by means of the formaldehyde-induced fluorescence method, we have attempted to specify the identity of the amines present in these cells by an immunohistological technique. Using a recently developed anti-dopamine serum, we have demonstrated that the majority of the cate cholaminergic median neurosecretory cells contain dopamine. Moreover, dopamine is present in some cell bodies of other zones of the brain, i.e. the median subocellar neurosecretory cells, perikarya in external areas of the protocerebrum, below the calyces, around the pedunculus, in the optic lobes (between the lobula and the medulla, between the medulla and the lamina), and in external zones of the tritocerebrum. Among the structured neuropils, which were particularly fluorescent in the formaldehyde-induced fluorescence method, only the pedunculus, the posterior part of the central body, the external zones of the α- and β lobes and the proximal part of the lamina contain little dopamine.
