[Distribution of biogenic amines in the hippocampal formation in the rabbit].

The hippocampal formation (the hippocampus and the dentate fascia) of the rabbit was studied by histochemical fluorescent method of Falk to determine localization of monoaminergic terminals containing biogenic amines: noradrenalin, dophamine and serotonin. It was shown that monoaminenergic terminals in the hippocampus were in two zones of afferent terminations: in the zone of ending of the perforating way (str. lacunosum-moleculare of fields CA1 and CA2; str. moleculare of the dentate fascia) and in the subgranular zone of the hilum where a part of septofimbrial way terminated on granular neurons of the dentate fascia, the main cellular elements of the hipocampus (pyramidal, granular and basket cells of the hippocampus) did not contain biogenic amines.

[Distribution of biogenic amines and acetylcholinesterase in the mammillary nuclei of rabbits].

The distribution of biogenic amines (BA) and acetylcholinesterase (AChE) in mamillary nuclei of rabbits was studied by the methods of Falck, Karnovski and Roots. The general mass of BA was shown to localize in the terminals of the lateral mamillary nucleus and in the supramamillary area. The amount of BA-terminals in the medial nucleus is insignificant. Besides, the cells containing BA were found in the lateral part of the lateral nucleus. AChE is localized mainly in the neuropile and the cells of the medical nucleus and the cells of the lateral mamillary nucleus. The fornix and the mamillo-thalamic tract do not respond to AChE (poor activity in the mamillo-thalamic tract) and to BA. The obtained results suggest the afferents of the medial nucleus to be cholinergic, and those of the lateral nucleus - monoaminergic. Due to the presence of AChE-cells in the medial nucleus and BA-cells and AChE-cells in the lateral nucleus a supposition is possible that while the afferents of the nedial nucleus are cholinergic, the efferents of the lateral nucleus contain both AChE AND BA.
