dc.description.abstract | Total brain volume and regional brain size can vary in men and women. Sexual dimorphism
between the male and female brain starts in the fetal period under the influence of genetic
and hormonal factors. In addition, the newborn brain begins to change in terms of both
brain volume and morphology. In the present study, we evaluated gender-related changes in
brain volume in children 1–5 years old. Magnetic resonance images of 30 healthy children
aged 1–5 years old (15 male, 15 female) were obtained from the Department of Radiology,
Meram School of Medicine, University of Necmettin Erbakan. The Cavalieri method and
point-counting were used to determine the brain hemisphere volumes from these images.
The mean volumes of the right cerebrum in female and male children were 423.26 ± 110.62
cm
3
and 456.43 ± 161.39 cm3
, respectively, and those of the left cerebrum were 416.41 ±
103.51 cm3
and 460.42 ± 154.99 cm3
, respectively. There were no significant differences in
cerebrum hemisphere volumes between male and female children 1–5 years old (P > 0.05). | |
