Abstract
Neurons and glial cells were studied by means of
computerassisted morphometry in the segments of
the ventral and dorsal regions of the compact part
of the substantia nigra (CPSN) of the brain. The
material obtained at autopsy from 6 males and 3
females aged from 52 to 87 years. It was found
that in segments of the ventral CPSN region the
neuronal cell bodies and nuclei were larger than
those in the segments of the dorsal region. The
numerical density of neurons and gliocytes in the
ventrolateral segment was higher than in the
segments of the dorsal region. In the ventromedial
segment the glial index was lower than in the
segments of the dorsal region. The morphometric
differences found between CPSN segments must
be taken into account in the assessment of the
morphological changes in substantia nigra of the
brain, due to both age involution or pathological
process.
