AI Article Synopsis

  • The study aimed to analyze the brain characteristics of one-year-old infants using magnetic resonance imaging, focusing on individual differences like sex and brain hemisphere size.
  • Findings indicated that boys had larger telencephalic (cerebral) dimensions, while girls had larger brainstem structures, highlighting a sexual dimorphism in brain size.
  • Additionally, the research found that in most infants, the right hemisphere lobes were larger than the left, indicating a trend of interhemispheric asymmetry in their brain development.

Article Abstract

The present study was designed to give the integrated intravital morphometric characteristic of the brain of one-year-old infants taking into account their individual variation (sex-related, interhemispheric) using magnetic resonance tomography. The research has revealed a sexual dimorphism of the brain dimensions: telencephalic dimensions were found to prevail in boys, while the dimensions of the brainstem structures were prevalent in girls. The interhemispheric asymmetry was detected in the brain of one-year-old infants; in most cases there was a prevalence of the dimensions of the right hemisphere lobes over those ones of the left hemisphere.
