[The study of V. I. Lenin's brain]

The investigation of V. I. Lenin's brain was carried out on the basis of study of 1108 cytoarchitectonical slices (thickness of 20 mu), stained by Kresil-Violett (Nissl's method) and 558 slices of fibres stained by Geidenhain's method. This is the first in the history of science detailed microscopical study of the man brain, initiated to creation of russian architectonics (as a science of the brain architecture); this study was served for a foundation of structural basis of science on the brain individual variability of different people including prominent persons. The results of this study is compared with a data of the later macroscopic and microscopic investigation of many persons brain with different professions and abilities. The next peculiarities of the Lenin's brain have been written: 1. The relief complexity and peculiarities of sulci and gyri configuration, especially in frontal lobe. 2. The big percentage of the cortex in a deep of the sulci (so called intrasulcal component), and as a result of the increasing of the summarised size of the cortex cerebri. 3. The riches and pronunciation of s.c. limitrophic adaptation's zones between different areas, especially in the frontal lobe and in the other associative cortical structures. 4. The originality in relation in size between area in one region and regarding to the whole cortex surface. The prevail of the size and variability of phylogenetically new (associative) regions, especially of frontal one (which takes part in the function of situation estimation, prognostication, generalization) and also of parietal and temporal cortex; the phylogenetically old zone are more stable. 5. The large number of the especially big pyramidal neurons in sublayer III (III(3)), that can be supposedly looked as a structural basis of the rich associative connections between different cortical regions. The above mentioned peculiarities have been done as a result of the study chiefly of the right brain hemisphere because the left one was seriously suffered as a result of the vessels damage of atherosclerosis origin.
