Probabilistic Lesion Mapping to Optimize Thalamotomy Targets for Focal Hand Dystonia

Annals of Neurology, Volume 99, Issue 5, Page 1227-1238, May 2026.
Objective Focal hand dystonia (FHD) severely impairs task‐specific motor control, yet the optimal surgical target for stereotactic intervention remains uncertain. This study aimed to identify the precise thalamic lesion site associated with symptomatic improvement and to clarify its network connectivity. Methods We retrospectively analyzed 164 patients

Feasibility study to unveil the potential: considerations of constrained spherical deconvolution tractography with unsedated neonatal diffusion brain MRI data

Frontiers in Radiology
PurposeThe study aimed to (1) assess the feasibility constrained spherical deconvolution (CSD) tractography to reconstruct crossing fiber bundles with unsedated neonatal diffusion MRI (dMRI), and (2) demonstrate the impact of spatial and angular ...

An error analysis of probabilistic fibre tracking methods: average curves optimization [PDF]

, 2009
Fibre tractography using diffusion tensor imaging is a promising method for estimating the pathways of white matter tracts in the human brain. The success of fibre tracking methods ultimately depends upon the accuracy of the fibre tracking algorithms and

Tau Pathology in Alzheimer's Disease Uniquely Affects Sulcal Depths

Annals of Neurology, Volume 99, Issue 5, Page 1343-1353, May 2026.
Objective Though it is widely known that tau deposition affects brain structure, the precise localization of these effects is poorly understood, especially in relation to gyral and sulcal anatomy. We investigated whether tau pathology in Alzheimer's disease (AD) preferentially affects sulci, and particularly sulcal depths.

Affective and cognitive prefrontal cortex projections to the lateral habenula in humans

, 2014
Anterior insula (AI) and dACC are known to process information about pain, loss, adversities, bad, harmful or suboptimal choices and consequences that threaten survival or well-being.

Hominoid‐specific calretinin‐immunopositivity of the optic radiation (geniculocalcarine tract)

The Anatomical Record, Volume 309, Issue 5, Page 1343-1367, May 2026.
Calretinin‐immunostained coronal section through the primary (V1) and extrastriate (ExSt) cortex of the lar gibbon. Note that the optic radiation (OR) is strongly calretinin‐immunoreactive. This calretinin‐immunopositivity of the OR distinguishes the Hominoidea from other primates in terms of the neurochemistry of the OR.

Comparison of Distances for Supervised Segmentation of White Matter Tractography

, 2017
Tractograms are mathematical representations of the main paths of axons within the white matter of the brain, from diffusion MRI data. Such representations are in the form of polylines, called streamlines, and one streamline approximates the common path ...

White Matter Tract Alterations in Bipolar Disorder: A Systematic Review and Meta‐Analysis of Diffusion Tensor Imaging Studies

Brain and Behavior, Volume 16, Issue 5, May 2026.
This systematic review and meta‐analysis synthesizes diffusion tensor imaging evidence of white matter microstructural abnormalities in bipolar disorder. Across published studies, patients with bipolar disorder showed reduced fractional anisotropy in several major white matter tracts, including the corpus callosum, cingulum bundle, corona radiata ...

Trait‐Relevant Tasks Improve Personality Prediction From Structural‐Functional Brain Network Coupling

Human Brain Mapping, Volume 47, Issue 7, May 2026.
Significant associations between the Big Five personality traits and structural‐functional brain network coupling are absent during resting state but emerge during trait‐relevant tasks. Carefully designed trait‐relevant tasks may amplify individual differences in trait‐related neural characteristics and thereby enhance their detectability.
