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 ...

Diffusion tensor tractography of brainstem fibers and its application in pain.
PLoS ONE, 2020 Evaluation of brainstem pathways with diffusion tensor imaging (DTI) and tractography may provide insights into pathophysiologies associated with dysfunction of key brainstem circuits.

Connectivity-based parcellation of the thalamus explains specific cognitive and behavioural symptoms in patients with bilateral thalamic infarct [PDF]
A novel approach based on diffusion tractography was used here to characterise the cortico-thalamic connectivity in two patients, both presenting with an isolated bilateral infarct in the thalamus, but exhibiting partially different cognitive and ...

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 ...

Diffusion tractography of the fornix in schizophrenia [PDF]
Schizophrenia Research, 2009 White matter fiber tracts, especially those interconnecting the frontal and temporal lobes, are likely implicated in pathophysiology of schizophrenia. Very few studies, however, have focused on the fornix, a compact bundle of white matter fibers, projecting from the hippocampus to the septum, anterior nucleus of the thalamus and the mamillary bodies ...

Probabilistic MRI tractography of the optic radiation using constrained spherical deconvolution: a feasibility study. [PDF]
PLoS ONE, 2015 Imaging the optic radiation (OR) is of considerable interest in studying diseases affecting the visual pathway and for pre-surgical planning of temporal lobe resections.

Pitch as a Shared Code for Music and Speech: Behavioral and Neural Evidence From Stroke Patients. [PDF]
Brain BehavABSTRACT Introduction Accurate pitch processing, including the ability to discriminate small differences in pitch, is essential for interpreting the melodic structure of both music and speech. However, the extent to which pitch discrimination is a shared auditory‐perceptual processing component in these domains remains unclear.
