Brain cortical volume and area from Freesurfer's parcellation in a sample of healthy volunteers from South America
<p>This dataset aims to deepen the analysis of cortical gyral and sulcal asymmetry of the entire cerebral cortex of healthy adult individuals by quantifying the gray matter content of the right and left hemispheres in a reference sample from South America. The subjects were sampled from populations scarcely represented in MRI research, which tends to be biased towards groups of European ancestry from Europe and North America. In contrast, the population under study is an admixture of Native American, European, and African components that contributed to a variable extent to their gene pool. Consequently, this study will add to expanding the diversity in brain morphometric data and the construction of more population-representative references.</p>

Data from: Joint analysis of cortical area and thickness as a replacement for the analysis of the volume of the cerebral cortex
Cortical surface area is an increasingly used brain morphology metric that is ontogenetically and phylogenetically distinct from cortical thickness and offers a separate index of neurodevelopment and disease. However, the various existing methods for assessment of cortical surface area from magnetic resonance images have never been systematically compared. We show that the surface area method implemented in FreeSurfer corresponds closely to the exact, but computationally more demanding, mass-conservative (pycnophylactic) method, provided that images are smoothed. Thus, the data produced by this method can be interpreted as estimates of cortical surface area, as opposed to areal expansion. In addition, focusing on the joint analysis of thickness and area, we compare an improved, analytic method for measuring cortical volume to a permutation-based nonparametric combination (NPC) method. We use the methods to analyze area, thickness and volume in young adults born preterm with very low birth weight, and show that NPC analysis is a more sensitive option for studying joint effects on area and thickness, giving equal weight to variation in both of these 2 morphological features.
