A Direct Cortico-Nigral Pathway as Revealed by Constrained Spherical Deconvolution Tractography in Humans [PDF]

Frontiers in Human Neuroscience, 2016
Substantia nigra is an important neuronal structure, located in the ventral midbrain, that exerts a regulatory function within the basal ganglia circuitry through the nigro-striatal pathway.

An atlas of white matter anatomy, its variability, and reproducibility based on constrained spherical deconvolution of diffusion MRI [PDF]

NeuroImage, 2022
Virtual dissection of white matter (WM) using diffusion MRI tractography is confounded by its poor reproducibility. Despite the increased adoption of advanced reconstruction models, early region-of-interest driven protocols based on diffusion tensor ...

Retrospective Comparative Analysis of Diffusion Tensor and Constrained Spherical Deconvolution Tractography Models in a Clinical Neurosurgical Navigation Platform [PDF]

Neurologia Medico-Chirurgica
Tractography is a technique for visualizing the trajectories of white matter pathways. The most widely used model, the diffusion tensor imaging, assumes a single fiber orientation within each voxel.
