Anatomical Sciences Education, EarlyView.Abstract The study of neuroanatomy is fundamental in many scientific fields. Despite this, it is a challenging subject for students. As technology evolves, it is being increasingly incorporated into educational methods, including the teaching of neuroanatomy. Three‐dimensional (3D) visualizations are well suited for displaying neuroanatomy.

Altered structural and effective connectivity in anorexia and bulimia nervosa in circuits that regulate energy and reward homeostasis. [PDF]
, 2016 Anorexia and bulimia nervosa are severe eating disorders that share many behaviors. Structural and functional brain circuits could provide biological links that those disorders have in common.

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.

Beyond crossing fibers: Bootstrap probabilistic tractography using complex subvoxel fiber geometries
Frontiers in Neurology, 2014 Diffusion magnetic resonance imaging fiber tractography is a powerful tool for investigating human white matter connectivity in vivo. However, it is prone to false positive and false negative results, making interpretation of the tractography result ...

Extracting the Groupwise Core Structural Connectivity Network: Bridging Statistical and Graph-Theoretical Approaches [PDF]
, 2017 Finding the common structural brain connectivity network for a given population is an open problem, crucial for current neuro-science. Recent evidence suggests there's a tightly connected network shared between humans.

Nosotchu, 2004 脳には白質線維の方向による水の拡散のしやすさの違い(拡散異方性diffusion anisotropy)があり,条件を満たした撮像を行い,テンソルを用いて解析すると,白質による拡散異方性の程度(白質によりどれだけ水分子が白質の方向に沿って動きやすく,白質と直交する方向に動きにくいかの程度)が定量化でき,さらに白質線維の方向も知ることができる.我々は拡散テンソルデータから白質線維による異方性を高速に追跡して拡散テンソルから見た"白質路"を描出するソフトを開発し,その臨床応用を行った.錐体路近傍の急性期脳梗塞においては,拡散テンソルtractographyにより,錐体路と梗塞との3次元的関係がより明瞭に描出され,予後予想に役立つことが示された.脳動静脈奇形などの脳血管障害 ...

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 ...
