We provide a detailed morphometric analysis of eight transmission electron micrographs (TEMs) obtained from the corpus callosum of one cynomolgus macaque. The raw TEM images are included in the article, along with the distributions of the axon calibe

Diffusion magnetic resonance imaging fiber tractography is a powerful tool for investigating human white matter connectivity in vivo. However, it is prone to false positive and false negative results, making interpretation of the tractography result

A central goal in neuroscience is the development of a comprehensive mapping between structural and functional brain features. Computational models supportin vivoinvestigation of the mechanisms mediating this relationship but currently lack the requi

PURPOSE In this work, we propose that Δ B1+ -induced errors in magnetization transfer (MT) saturation (MTsat ) maps can be corrected with use of an R1 and B1+ map and through numerical simulations of the sequence. THEORY AND METHODS One healthy subj

Purpose Most voxels in white matter contain multiple fiber populations with different orientations and levels of myelination. Conventional T1 mapping measures 1 T1 value per voxel, representing a weighted average of the multiple tract T1 times. Inver

The fiber g-ratio is defined as the ratio of the inner to the outer diameter of the myelin sheath. This ratio provides a measure of the myelin thickness that complements axon morphology (diameter and density) for assessment of demyelination in diseas
Diffusion MRI is a magnetic resonance imaging technique in which the contrast mechanism is determined by the microscopic mobility of water molecules. In vivo, tissue structures such as cell membranes impede the diffusive motion of water molecules, me

The fiber g-ratio is the ratio of the inner to the outer diameter of the myelin sheath of a myelinated axon. It has a limited dynamic range in healthy white matter, as it is optimized for speed of signal conduction, cellular energetics, and spatial c

Diffusion tensor imaging (DTI) is a powerful technique for imaging axonal anatomy in vivo and its automatic segmentation is important for quantitative analysis and visualization. Application of the watershed transform is a recent approach for robustl
