Reducing Model Uncertainty in Crossing Fiber Tractography
, 2021 Diffusion MRI (dMRI) tractography permits the non-invasive reconstruction of major white matter tracts, and is therefore widely used in neurosurgical planning and in neuroscience. However, it is affected by various sources of uncertainty.

Automated white matter fiber tract identification in patients with brain tumors
NeuroImage: Clinical, 2017 We propose a method for the automated identification of key white matter fiber tracts for neurosurgical planning, and we apply the method in a retrospective study of 18 consecutive neurosurgical patients with brain tumors.

Anatomical Sciences Education, EarlyView.Abstract Teaching white matter (WM) anatomy to undergraduates is challenging. This is partly because WM fibers are oriented intricately and Klingler's dissection, the gold standard method used to demonstrate it, often requires time, advanced anatomical knowledge, and refined dissection skills.

Show Me the Brain!!: A modern approach to neuroanatomy education
Anatomical Sciences Education, EarlyView.Abstract Show Me the Brain!! (SMtB) is a digital system for interactive graphics that is designed to support instruction in neuroanatomy and neuroscience. It will soon be made open‐source and freely available. SMtB bridges medical and traditional neuroanatomy instruction with the computational systems and representational conventions common in ...

What's a White Matter ‘Fiber’?
Clinical Anatomy, EarlyView.ABSTRACT White matter anatomy is investigated using methods that operate at markedly different spatial scales and rely on distinct biological and physical principles. Nevertheless, the term “fiber” is routinely applied to the outputs of tract‐tracing studies, diffusion MRI tractography, and postmortem fiber dissection, often as though these entities ...

Absence seizures: Update on signaling mechanisms and networks
Epilepsia Open, EarlyView.Abstract Absence seizures (AS) are a hallmark of genetic generalized epilepsies (GGE), characterized by brief episodes of impaired consciousness accompanied by electroencephalographic spike‐and‐wave discharges (SWDs). Traditionally attributed to cortico‐thalamo‐cortical (CTC) dysrhythmia, emerging evidence suggests a more intricate pathophysiological ...

Two-tensor Fiber Tractography [PDF]
, 2007 Estimating white matter fiber pathways from a diffusion tensor MRI dataset has many important applications in medical research. However, the standard approach of performing tracking on single-tensor estimates per voxel is confounded by regions of ...
