Using the sensitive and specific fluorescence method of FALCK and HILLARP in combination with electron microscopy and biochemical methods for the localization and estimation of the monoamines, their immediate precursors, and the pertinent enzymes, monoaminergic nervous mechanisms are studied in a bread comparative material. The fluorescence method has been thoroughly studied both from the chemical and histochemical point of view and is now well standardized. Monoaminergic mechanisms constitute a considerable part of the mollusc nervous system. These mechanisms were studied in both gastopod and bivalve species. Studies of similar type were carried out on annelids and crustaceans and these have disclosed further monoaminergic mechanisms. Some of the monoaminergic system in the upper brain stem in the pigeon have been mapped out. A comprehensive study is performed on the sympathetic innervation of the eye and its adnexa. The dilator muscle of the rat iris was found to contain a hitherto unknown cholinergic ground-lexus. Although the cholinergic receptor is not identified there are reasons for believing that an interaction exists between these two terminal plexus. The monoaminergic mechanisms in the pineal gland are studied in several mammalian species. Monoaminergic mechanisms in the hypothalamo -hypophysical complex are under investigation. In the cod, the existence of short noradrenergic neurons having their cell bodies located peripherally near the effector cells was demonstrated. Author
