This study introduces a novel method for functionally meaningful cortical surface parcellation using individual anatomy. The approach defines a complete surface partition for better anatomical and functional description.

Area of Science:

  • Neuroimaging
  • Computational Neuroscience
  • Brain Mapping

Background:

  • Cortical surface organization is complex.
  • Understanding functional regions requires precise parcellation.
  • Existing methods may not fully integrate anatomical and functional data.

Purpose of the Study:

  • To present an original method for cortical surface parcellation.
  • To achieve functionally meaningful parcellation based on individual anatomy.
  • To offer a novel way to describe cortical organization anatomically and functionally.

Main Methods:

  • Developed an anatomically constrained, surface-based coordinate system.
  • Defined a complete partition of the cortical surface.
  • Applied the method to functional somatotopy experimental data.

Main Results:

  • Successfully parcellated the cortical surface into functionally meaningful regions.
  • Demonstrated the method's ability to integrate anatomical constraints.
  • Validated the approach using somatotopy experiments.

Conclusions:

  • The proposed method provides a new framework for cortical surface analysis.
  • It enables a comprehensive description of cortical organization.
  • This approach has potential applications in neuroimaging research and clinical settings.
