“Hands‐On” white matter anatomy: Using Air Anatomy gestures and tractography on simple brain sections to enhance teaching of white matter directions

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 ...

Fiber tracking in q-ball fields using regularized particle trajectories [PDF]

, 2005
Most of the approaches dedicated to fiber tracking from diffusion-weighted MR data rely on a tensor model. However, the tensor model can only resolve a single fiber orientation within each imaging voxel.

Impaired Motor Competence in Children and Adolescents With Autism Spectrum Disorder: Evidence From a Systematic Review and Meta‐Analysis

Autism Research, EarlyView.
ABSTRACT Autism spectrum disorder (ASD) is frequently associated with motor difficulties that may affect daily functioning, participation in physical activity, and developmental outcomes. Although motor impairments have been widely reported in this population, comparative evidence against typically developing (TD) peers remains fragmented across ...

The Evolving Role of Clinical Anatomy: From Definition to Contribution

Clinical Anatomy, EarlyView.
ABSTRACT The term “clinical anatomy” is widely used in education and research, yet its conceptual boundaries continue to be interpreted in various ways. Prior consensus‐based efforts have emphasized integration, collaboration, and clinical relevance as central features of the field and have provided an important foundation for interdisciplinary ...

Tractography of Porcine Meniscus Microstructure Using High-Resolution Diffusion Magnetic Resonance Imaging

Frontiers in Endocrinology, 2022
To noninvasively evaluate the three-dimensional collagen fiber architecture of porcine meniscus using diffusion MRI, meniscal specimens were scanned using a 3D diffusion-weighted spin-echo pulse sequence at 7.0 T.

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 ...

Multiple indices of diffusion identifies white matter damage in mild cognitive impairment and Alzheimer's disease [PDF]

, 2010
The study of multiple indices of diffusion, including axial (DA), radial (DR) and mean diffusion (MD), as well as fractional anisotropy (FA), enables WM damage in Alzheimer's disease (AD) to be assessed in detail.

Neurocircuitry of Deep Brain Stimulation for Obsessive-Compulsive Disorder as Revealed by Tractography: A Systematic Review

Frontiers in Psychiatry, 2021
Objective: Deep brain stimulation (DBS) was proposed in 1999 to treat refractory obsessive-compulsive disorder (OCD). Despite the accumulated experience over more than two decades, 30–40% of patients fail to respond to this procedure.

Direct cortical stimulation–evoked symptoms in the human temporal pole: A systematic review

Epileptic Disorders, EarlyView.
Abstract The temporal pole represents a key node within temporolimbic networks and may contribute to seizure generation in temporal lobe epilepsy. Direct cortical stimulation (DCS), performed during intracranial presurgical evaluation, is a valuable method for delineating the seizure onset zone by reproducing electro‐clinical features of a patient's ...
