Abstract

The study of the normal cytoarchitecture of the reticular formation was begun at Neustadt in 1945 and concluded at the Montreal Neurological Institute, after expansion of the project to include all of the gray masses of the lower brain stem. Blocks for sectioning were taken from fifteen brain stems (fixed by immersion or perfusion), from the pyramidal decussation to the mammillary bodies. There is first a series of nineteen semischematic cross sections, accompanied by low-power photomicrographs of the same representative levels. The next major part contains descriptions and higher-magnification pictures of the individual nuclei. The sheet size permits reproductions in considerable detail, blurred in physically smaller articles and monographs. The pictures have been beautifully reproduced by Aberegg-Steiner & Cie., A. G., in Berne. Repetition of legends and abbreviations on each spread of the initial atlas is another boon which the large plate size permits.
