Brainprints: Computer-Generated Two-Dimensional Maps of the Human Cerebral Cortex in vivo

Area of Science:

• Neuroscience
• Anatomical Imaging
• Quantitative Biology

Background:

• Accurate quantitative analysis of human brain anatomy is crucial for understanding neurological disorders.
• Existing methods may lack the precision or in vivo capabilities for detailed morphological and functional assessments.

Purpose of the Study:

• To present a novel in vivo method for the quantitative analysis of human brain anatomy.
• To demonstrate the technique's utility in measuring cortical regions and surface areas.
• To explore potential applications in cognitive and neurological research.

Main Methods:

• Development of an in vivo quantitative analysis technique for human brain anatomy.
• Planimetric measurement of unfolded brain regions of interest.
• Generation of 2D cortical maps and surface area calculations using magnetic resonance imaging (MRI).
• Reconstruction and measurement of published post-mortem hemisphere data.

Main Results:

• Successful application of the in vivo method for quantitative anatomical analysis.
• Presentation of 2D cortical maps and surface area data from monozygotic twins.
• Validation of the technique through measurements of published human and rhesus monkey brain data.

Conclusions:

• The described in vivo method offers a powerful tool for quantitative analysis of human brain anatomy.
• This technique has significant potential for studying brain organization in relation to performance in both healthy and neurologically impaired individuals.
• Further research can leverage this method to advance our understanding of brain-behavior relationships.
