Surface-based atlases enable detailed visualization of cerebral cortex convolutions and functional activity. This approach facilitates objective comparisons of brain structures and functions across species, aiding in the identification of homologous regions.

Area of Science:

  • Neuroscience
  • Comparative Anatomy
  • Brain Imaging

Background:

  • Cerebral cortex convolutions present challenges for analysis.
  • Surface reconstructions offer a substrate for visualization.
  • Atlases are crucial for understanding brain organization.

Purpose of the Study:

  • Illustrate the utility of surface-based atlases for human and macaque brains.
  • Represent cortical organization and function.
  • Facilitate cross-species comparisons of brain regions.

Main Methods:

  • Utilized explicit surface reconstructions of the cerebral cortex.
  • Employed surface-based atlases for human and macaque brains.
  • Applied surface-based registration for quantitative analysis.
