Theinvestigation of V. I. Lenin‘s brain was carried out on the basis ofstudy of 1108 cytoarchitectonical slices (thickness of 20 mu), stainedby Kresil-Violett (Nissl‘s method) and 558 slices of fibres stained byGeidenhain‘s method. This is the first in the history of sciencedetailed microscopical study of the man brain, initiated to creation ofrussian architectonics (as a science of the brain architecture); thisstudy was served for a foundation of structural basis of science on thebrain individual variability of different people including prominentpersons. The results of this study is compared with a data of the latermacroscopic and microscopic investigation of many persons brain withdifferent professions and abilities. The next peculiarities of theLenin‘s brain have been written: 1. The relief complexity andpeculiarities of sulci and gyri configuration, especially in frontallobe. 2. The big percentage of the cortex in a deep of the sulci (socalled intrasulcal component), and as a result of the increasing of thesummarised size of the cortex cerebri. 3. The riches and pronunciationof s.c. limitrophic adaptation‘s zones between different areas,especially in the frontal lobe and in the other associative corticalstructures. 4. The originality in relation in size between area in oneregion and regarding to the whole cortex surface. The prevail of thesize and variability of phylogenetically new (associative) regions,especially of frontal one (which takes part in the function ofsituation estimation, prognostication, generalization) and also ofparietal and temporal cortex; the phylogenetically old zone are morestable. 5. The large number of the especially big pyramidal neurons insublayer III (III(3)), that can be supposedly looked as a structuralbasis of the rich associative connections between different corticalregions. The above mentioned peculiarities have been done as a resultof the study chiefly of the right brain hemisphere because the left onewas seriously suffered as a result of the vessels damage ofatherosclerosis origin.
