Women exhibit greater cortical complexity than men in frontal and parietal brain regions. This finding, using advanced 3D magnetic resonance imaging, suggests increased surface area may explain behavioral gender differences.

Area of Science:

  • Neuroscience
  • Human Anatomy
  • Brain Imaging

Background:

  • Cortical complexity, measuring brain surface gyrification and fissuration, lacks comprehensive gender-based characterization.
  • Understanding these differences is crucial for interpreting brain structure-behavior relationships.

Purpose of the Study:

  • To investigate and quantify gender differences in human cortical complexity.
  • To explore the implications of these differences for brain volume and behavior.

Main Methods:

  • Utilized a novel three-dimensional (3D) analytic technique.
  • Employed magnetic resonance imaging (MRI) for detailed brain surface analysis.

Main Results:

  • Identified significantly greater gyrification in women compared to men.

  • Observed this difference predominantly in the frontal and parietal cortical regions.

    • Conclusions:

    • Women possess higher cortical complexity, indicating a larger cortical surface area.
    • This increased surface area may compensate for brain volume disparities and contribute to observed behavioral gender differences.
