Abstract
By means of a method for the stereomicroscopical demonstration of neurolipofuscines in sections ranging from 400 up to 800 μm in thickness (Braak, 1970), the distribution pattern of these pigments all over the various layers and sectors of the cornu ammonis of man is described. Additionally Golgi studies were made for an improved interpretation of the pigment picture. Our new technique utilizing the successive examination of both the Golgi and the pigment picture of individual neurons allows a clear determination of the cell types by distinguishing characteristics of the pigment deposits. Thus, the pigment preparations allow to separate unequivocally the pyramids from the various types of stellate cells. Hence, the qualitative results of the Golgi studies are translated into the language of the pigment preparations, giving quantitative information about the distribution pattern and packing density of pyramids and the various types of interneurons. Pigmentarchitectonic studies are therefore of great value, if deciphering of the bewildering maze of the human cerebral cortex is attempted.
