In this article, we studied individual features of the macroscopic structure of Broca’s area
of the brains in 9 women (18 hemispheres) aged from 20 to 30 years, without any mental
or neurological disorders. By using MRI, the structures of the sulci and gyri of the pars
triangularis and pars opercularis of Broca’s area were studied: the anterior and ascending
rami of the lateral sulcus, the radial, diagonal, precentral, inferior frontal, and lateral sulci.
We also studied the relationship between the pars triangularis and pars opercularis as well
as their relationships with neighboring cortical structures. We measured the volume of the
pars triangularis and pars opercularis and the thickness of their cortex. Signifcant individual
variability in the location and relationships between the anterior ramus of the lateral sulcus
and the ascending ramus of the lateral sulcus, as well as structural features of the pars triangularis and pars opercularis of Broca’s area were demonstrated.
