Abstract
The histochemical localization of lipids, as obtained by the application of the acid hematein test of Baker (1946), the controlled chromation method of Elftman (1958), the copper phthalocyanin method of Pearse (1955) and the phosphomolybdic acid method of Landing, Uzman and Whipple (1952), in avian central nervous tissues has been given. For the localization of intraneuronal phospholipids, good results were obtained only with the controlled chromation method of Elftman (1958). The intraneuronal phospholipid appears to be present in the form of granular bodies almost uniformly distributed in the cell perikaryon. The other methods given above failed to demonstrate intraneuronal lipids. However, all these work for the phospholipids of myelin. The results obtained have been discussed and compared with those available in the literature on neurohistochemistry in general.
