The Emerging Role of Tractography in Deep Brain Stimulation: Basic Principles and Current Applications

Brain Sciences, 2018
Diffusion tensor imaging (DTI) is an MRI-based technique that delineates white matter tracts in the brain by tracking the diffusion of water in neural tissue.

Diffusion MRI and α‐Synuclein Seed Amplification Status in Parkinson's Disease

Annals of Neurology, Volume 100, Issue 2, Page 295-304, August 2026.
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.

The Flail Limb Syndrome

Muscle &Nerve, Volume 74, Issue 2, Page 281-292, August 2026.
ABSTRACT The flail limb syndrome is primarily a lower motor neuron disorder that initially affects proximal arm muscles (flail arm syndrome—FAS) or distal leg muscles (flail leg syndrome—FLS). Both were recognized early on (1886 for FAS and 1918 for FLS) as somewhat distinct from classic amyotrophic lateral sclerosis (ALS).

Automated Surface‐Based Segmentation of Deep Gray Matter Regions Based on Diffusion Tensor Images Reveals Unique Age Trajectories Over the Healthy Lifespan

NMR in Biomedicine, Volume 39, Issue 8, August 2026.
This paper introduces a novel, automated deep gray matter segmentation method that relies exclusively on diffusion‐weighted imaging, eliminating the need for T1‐weighted images. When applied to a lifespan cohort from ages 5 to 90, the technique successfully mapped distinct, nonlinear developmental and aging trajectories for microstructural diffusion ...

Regional Brain Volume Differences Were Associated With Behavioural Outcomes in Children Born Preterm: A Systematic Review

Acta Paediatrica, Volume 115, Issue 8, Page 1581-1592, August 2026.
ABSTRACT Aim This systematic review explored associations between brain structural volumes and behavioural outcomes in children born preterm up to 32 weeks of gestation. Methods PubMed, PsycINFO, Scopus and Web of Science were searched for papers published in English from 1 January 2013 to 7 November 2023.

Dissecting the Strain and Sex Specific Connectome Signatures of Unanesthetized C57BL/6J and DBA/2J Mice Using Magnetic Resonance Imaging

Genes, Brain and Behavior, Volume 25, Issue 4, August 2026.
C57BL/6J and DBA/2J mice were used to investigate strain and sex‐specific features of the brain connectome in awake animals using magnetic resonance imaging (MRI). By combining resting‐state and diffusion MRI, we found significant differences in the motor, sensory, limbic, and salience networks between C57BL/6J and DBA/2J mice.

Real-time tractography: computation and visualization

Brain Structure and Function
Did you know that even though tractography is often considered a computationally expensive and offline process, the latest algorithms can now be performed in real-time without sacrificing accuracy? Interactive real-time tractography has proven to be valuable in surgical planning and has the potential to enhance neuromodulation therapies, highlighting ...

Directionality of longitudinal associations between frontostriatal structural connectivity and depressive symptoms in adolescent girls

Journal of Child Psychology and Psychiatry, Volume 67, Issue 8, Page 1361-1370, August 2026.
Background Individual differences in the structure and function of the frontostriatal reward network have been related to depression. However, there is a strong need for prospective, longitudinal studies aiming to understand the role of frontostriatal networks in depression in a developmental context.

Modular brain networks shape amyloid‐driven tau spread and cognitive decline

Alzheimer's &Dementia, Volume 22, Issue 7, July 2026.
Abstract INTRODUCTION Alzheimer's disease involves trans‐synaptic spread of tau pathology from temporal lobe epicenters, driven by amyloid beta (Aβ) deposition. How modular brain network architecture shapes this process and the ensuing cognitive decline remains incompletely understood.
