[The problem of the individual variability of the human brain].
Series of frontal sections, 20 microns thick, were used to study the individual cytoglio-architectonic features of fields 8.8, 39, 40, 41, 43, 44, 45, 47 of the caudate nucleus, dorsomedial nucleus of the thalamus, Meynert's nucleus in 12 persons aged 29 to 89 years. The profile fields of neurons, their density and the density of gliocytes, including perineuronal ones were measured by computed morphometry, the cellular composition was determined from size of neurons, as well as the neuroglial and neuroperineuronal indices were defined. In 6 cases (distinguished, gifted persons), all the formations under study showed structural signs (abundant satellitosis, predominant large neurons, etc.) suggesting that there is a high functioning of nerve cells whose quantitative parameters are greater than those in other cases.
