- Description
This dataset includes 3D scanning electron microscopy (SEM) images of a female mouse corpus callosum and MATLAB code for random walker (RaW) segmentations of myelinated axons. The code additionally characterizes inner axonal diameters and fiber orientation dispersion within segments of the intra-axonal spaces and myelin sheaths. In the study, a female 8-week-old C57BL/6 mouse was perfused trans-cardiacally...

- Description
This study demonstrated that time-dependent diffusion MRI can detect subtle axonal changes in brain injury by identifying structural signatures of diffusive dynamics of water along axons. Scattering theory reveal two parameters that determine the diffusive dynamics of water along axons: the average reciprocal cross-section and the variance of long-range cross-sectional fluctuations. This theoretical...
