We report on surface-based analyses that enhance our understanding of human cortical organization, including its convolutions and its parcellation into many distinct areas. The surface area of human neocortex averages 973 cm(2) per hemisphere, based on cortical midthickness surfaces of 2 cohorts of subjects. We implemented a method to register individual subjects to a hybrid version of the FreeSurfer "fsaverage" atlas whose left and right hemispheres are in precise geographic correspondence…

Cortical parcellations of the macaque monkey analyzed on surface-based atlases.
TLDR
This work used landmark-constrained SBR to register many published parcellation schemes to the macaque F99 surface-based atlas, which enables objective comparison of both similarities and differences across parcellations.
A sub+ cortical fMRI-based surface parcellation
TLDR
This work generates a functional parcellation of both the cortical and subcortical surfaces that provides greater homogeneity of functional connectivity patterns than do arbitrary parcellations matching in the number and size of parcels and provides an improved fit to the complexity of the life-span changes in the white/gray contrast data.
A multi-modal parcellation of human cerebral cortex
TLDR
Using multi-modal magnetic resonance images from the Human Connectome Project and an objective semi-automated neuroanatomical approach, 180 areas per hemisphere are delineated bounded by sharp changes in cortical architecture, function, connectivity, and/or topography in a precisely aligned group average of 210 healthy young adults.
A sub+cortical fMRI‐based surface parcellation
TLDR
The surface-based approach is extended to include also the subcortical deep gray‐matter structures, thus achieving a uniform representation across both cortex and subcortex, suitable for use with surface‐based metrics that span these structures, for example, white/gray contrast.
Hemispheric asymmetries in cortical and subcortical anatomy
TLDR
Improved Freesurfer-based automated methods are used to analyse the properties of the cortex and seven subcortical structures in 138 young adult subjects to resolve some of the inconsistencies in previous studies of hemispheric asymmetries in brain anatomy.
Surface-based characterization of healthy human adult cortex : An investigation of its morphological variability, late maturation and asymmetries
TLDR
This study demonstrated that there were correlations between thickness and surface area asymmetries, characteristics of the cortex organization, and these areas are key sites for which it now remains to study the anatomical relevance as markers of brain lateralization and its functional correlates.
Comparison of Surface Area and Cortical Thickness Asymmetry in the Human and Chimpanzee Brain.
TLDR
Results of vertex-wise and ROI-based analyses that compared surface area and cortical thickness asymmetries in 3D MR images obtained for 91 humans and 77 chimpanzees provide evidence of there being substantial differences in asymmetry between the human and chimpanzee brain.
Mapping hemispheric asymmetries of the macaque cerebral cortex during early brain development
TLDR
It is revealed that most clusters of hemispheric asymmetries of cortical properties, such as surface area, cortical thickness, sulcal depth, and vertex positions, expand in the first 4 months of life, and evolve only moderately thereafter.
Parcellating Cerebral Cortex: How Invasive Animal Studies Inform Noninvasive Mapmaking in Humans
Generation and Evaluation of a Cortical Area Parcellation from Resting-State Correlations.
TLDR
The boundary map- derived parcellation contained parcels that overlapped with architectonic mapping of areas 17, 2, 3, and 4, and their connectivity patterns were reliable across individual subjects, suggesting that RSFC-boundary map-derived parcels provide information about the location and extent of human cortical areas.

Structural and Functional Analyses of Human Cerebral Cortex Using a Surface-Based Atlas
TLDR
The analysis supports a distinction between an anterior region in ventral occipito-temporal cortex that is selectively involved in form processing and a more posterior region (in or near areas VP and V4v) involved in both form and color processing.

Functional and structural mapping of human cerebral cortex: solutions are in the surfaces.
TLDR
This report discusses ways to compensate for the convolutions of the human cerebral cortex by using a combination of strategies whose common denominator involves explicit reconstructions of the cortical surface.
A Population-Average, Landmark- and Surface-based (PALS) atlas of human cerebral cortex.
TLDR
A new electronic atlas of human cerebral cortex that provides a substrate for a wide variety of brain-mapping analyses and is registered to other surface-based atlased to facilitate interchange of data and comparison across atlases is described.

Function-based Intersubject Alignment of Human Cortical Anatomy
TLDR
The method for aligning the functional neuroanatomy of individual brains based on the patterns of neural activity that are elicited by viewing a movie generalizes successfully to data obtained with another cognitive activation paradigm and improves group statistics in that experiment as measured by a standard general linear model (GLM) analysis.
High‐resolution intersubject averaging and a coordinate system for the cortical surface
TLDR
This work has developed a means for generating an average folding pattern across a large number of individual subjects as a function on the unit sphere and of nonrigidly aligning each individual with the average, establishing a spherical surface‐based coordinate system that is adapted to the folding pattern of each individual subject, allowing for much higher localization accuracy of structural and functional features of the human brain.

TLDR
The cytoarchitectonic probabilistic maps of the seven IPL areas provide a robust anatomical reference and open new perspectives for further structure–function investigations of the human IPL.

Brain size and cortical structure in the adult human brain.
TLDR
It is suggested that sex effects are explained by brain size effects in cortical structure at a macroscopic and lobar regional level, and that it is necessary to consider true relationships between cortical measures and brain size due to the limitations of linear stereotaxic normalization.
