Mapping anatomical connectivity patterns of human cerebral cortex using in vivo diffusion tensor imaging tractography.
This work utilized diffusion tensor imaging deterministic tractography to construct a macroscale anatomical network capturing the underlying common connectivity pattern of human cerebral cortex in a large sample of subjects and further quantitatively analyzed its topological properties with graph theoretical approaches.
Age- and Gender-Related Differences in the Cortical Anatomical Network
In this study, age and sex effects on the anatomical connectivity patterns of 95 normal subjects ranging in age from 19 to 85 years are investigated and the cerebral cortex is characterized as a weighted network of connected regions.
PANDA: a pipeline toolbox for analyzing brain diffusion images
A MATLAB toolbox named “Pipeline for Analyzing braiN Diffusion imAges” (PANDA) is developed, expected to substantially simplify the image processing of dMRI datasets and facilitate human structural connectome studies.
Voxel-based detection of white matter abnormalities in mild Alzheimer disease
Voxel-wise comparison of whole-brain anisotropy revealed widely distributed disintegration of white matter in mild Alzheimer disease (AD), which may be an independent factor in the progress of AD.
Effects of Different Correlation Metrics and Preprocessing Factors on Small-World Brain Functional Networks: A Resting-State Functional MRI Study
The results provide direct evidence regarding the influences of correlation metrics and specific preprocessing choices on both the global and nodal topological properties of functional brain networks and have important implications for how to choose reliable analytical schemes in brain network studies.
Asymmetry analysis of cingulum based on scale‐invariant parameterization by diffusion tensor imaging
An improved fiber‐based scheme rather than an ROI‐based analysis is introduced to study in DTI datasets of 31 normal subjects the asymmetry of the cingulum, which is one of the most prominent white matter fiber tracts of the limbic system.
Sex- and brain size-related small-world structural cortical networks in young adults: a DTI tractography study.
The findings suggest that anatomical network organization in the human brain is associated with sex and brain size and provide insights into the understanding of the structural substrates that underlie individual differences in behavior and cognition.
