Advanced Science, Volume 13, Issue 31, 4 June 2026.Geometry and connectivity are complementary structures, which have demonstrated their ability to represent the brain's functional activity. This study evaluates geometric and connectome eigenmodes as biologically informed constraints for EEG source localization.

Tractography of Meyer's Loop asymmetries
Epilepsy Research, 2014 The purpose of the current study was to use diffusion tensor imaging (DTI) to conduct tractography of the optic radiations (OR) and its component bundles and to assess both the degree of hemispheric asymmetry and the inter-subject variability of Meyer's Loop (ML).

Brain tissue properties differentiate between motor and limbic basal ganglia circuits [PDF]
Despite advances in understanding basic organizational principles of the human basal ganglia, accurate in vivo assessment of their anatomical properties is essential to improve early diagnosis in disorders with corticosubcortical pathology and optimize ...

AI‐Driven Mapping of Seizure Spread Patterns
Annals of Neurology, EarlyView.Objective The focus of epilepsy research has largely been on seizure onset; however, physicians typically examine the patterns of seizure spread past seizure onset as well. This study aims to align automated seizure analysis with clinical practice, leverage deep learning to standardize seizure annotations that varies among physicians, and understand ...

Diffusion MRI and α‐Synuclein Seed Amplification Status in Parkinson's Disease
Annals of Neurology, EarlyView.Objective Positive α‐synuclein seed amplification assay (SAA) is a biomarker found in most people with Parkinson's disease (PD). We explored if free‐water (FW) imaging detects microstructural differences in the brains of patients with early PD with SAA+ or SAA– status.

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 ...

, 2009 This chapter describes the underlying principles and most common techniques in diffusion tractography and covers deterministic streamline tractography and several different probabilistic approaches. Tractography is the process of integrating voxelwise fiber orientations into a pathway that connects remote brain regions.

Embarrassingly Parallel Acceleration of Global Tractography via Dynamic Domain Partitioning
Frontiers in Neuroinformatics, 2016 Global tractography estimates brain connectivity by organizing signal-generating fiber segments in an optimal configuration that best describes the measured diffusion-weighted data, promising better stability than local greedy methods with respect to ...

Validation of DTI tractography-based measures of primary motor area connectivity in the squirrel monkey brain. [PDF]
PLoS ONE, 2013 Diffusion tensor imaging (DTI) tractography provides noninvasive measures of structural cortico-cortical connectivity of the brain. However, the agreement between DTI-tractography-based measures and histological 'ground truth' has not been quantified. In

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.
