Multiscale Circuit Architecture Associated With Memory Dysfunction in Temporal Lobe Epilepsy
Advanced Science, EarlyView.A multiscale precision‐mapping framework reveals that memory impairment in temporal lobe epilepsy arises from the convergence of focal medial temporal pathology, strategic white matter disconnection, and limbic‐centered metabolic network dysfunction.

Advanced Science, EarlyView.DDSurfer reconstructs cortical surfaces directly from diffusion MRI without requiring T1‐weighted scans. By fusing complementary microstructural features and learning diffeomorphic deformations, it efficiently generates accurate white matter and pial surfaces, improving geometric fidelity and morphometric reliability across datasets for robust surface ...

Scoping literature review: Comparing MRI tractography methods for optic radiation analysis
The Anatomical Record, EarlyView.Abstract Accurate tractography mapping of the optic radiations is essential to avoiding post‐operative visual field deficits in patients undergoing temporal lobe surgery. This literature review highlights the current landscape of MRI tractography methods that are used to delineate the optic radiations (ORs), with a particular focus on the anterior ...

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.

Improved fiber tractography with Bayesian tensor regularization
NeuroImage, 2006 Diffusion tensor tractography suffers from the effects of noise and partial volume averaging (PVA). For reliable reconstruction of fiber pathways, tracking algorithms that are robust to these artifacts are called for. To meet this need, the present study establishes a novel Bayesian regularization framework for fiber tracking that takes into account ...

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 ...

NeuroImage, 2021 Diffusion MRI tractography is the only noninvasive method to measure the structural connectome in humans. However, recent validation studies have revealed limitations of modern tractography approaches, which lead to significant mistracking caused in part

In vivo fiber tractography using DT-MRI data [PDF]
Magnetic Resonance in Medicine, 2000 Fiber tract trajectories in coherently organized brain white matter pathways were computed from in vivo diffusion tensor magnetic resonance imaging (DT-MRI) data. First, a continuous diffusion tensor field is constructed from this discrete, noisy, measured DT-MRI data. Then a Frenet equation, describing the evolution of a fiber tract, was solved.
