Gamma suppression correlates with thalamic stimulation therapeutic response in intractable epilepsy

Epilepsia, EarlyView.
Abstract Objective In patients with drug‐resistant epilepsy who undergo anterior nucleus of the thalamus (ANT) deep brain stimulation (DBS), efficacy is assessed months after therapy initiation and clinicians have no guidance when choosing stimulation parameters due to the lack of real‐time biomarkers.

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.

Absence seizures: Update on signaling mechanisms and networks

Epilepsia Open, EarlyView.
Abstract Absence seizures (AS) are a hallmark of genetic generalized epilepsies (GGE), characterized by brief episodes of impaired consciousness accompanied by electroencephalographic spike‐and‐wave discharges (SWDs). Traditionally attributed to cortico‐thalamo‐cortical (CTC) dysrhythmia, emerging evidence suggests a more intricate pathophysiological ...

Novel planning pipeline utilizing the Surgical Theater system for pediatric epilepsy surgery

Epilepsia Open, EarlyView.
Abstract Objective Advances in the analysis and collation of radiographic datasets have enhanced presurgical planning for various neurosurgical procedures, including clipping of cerebral aneurysms, surgical resection of tumors, and arteriovenous malformation management.

Performance of unscented Kalman filter tractography in edema: Analysis of the two-tensor model

NeuroImage: Clinical, 2017
Diffusion MRI tractography is increasingly used in pre-operative neurosurgical planning to visualize critical fiber tracts. However, a major challenge for conventional tractography, especially in patients with brain tumors, is tracing fiber tracts that ...

On the cortical connectivity in the macaque brain: A comparison of diffusion tractography and histological tracing data

NeuroImage, 2020
Diffusion-weighted magnetic resonance imaging (DW-MRI) tractography is a non-invasive tool to probe neural connections and the structure of the white matter.

Transformer-Based T1-Tractography

2025 IEEE 22nd International Symposium on Biomedical Imaging (ISBI)
Diffusion MRI (dMRI) streamline tractography has been the gold standard for non-invasive estimation of white matter (WM) pathways in the human brain. Recent advancements in deep learning have enabled the generation of streamlines from T1-weighted (T1w) MRI, a more common imaging method.

Manual for clinical language tractography [PDF]

Acta Neurochirurgica, 2019
We introduce a user-friendly, standardized protocol for tractography of the major language fiber bundles.The introduced method uses dMRI images for tractography whereas the ROI definition is based on structural T1 MPRAGE MRI templates, without normalization to MNI space. ROIs for five language-relevant fiber bundles were visualized on an axial, coronal,

Transcriptional signatures of cortical morphometric variability in temporal lobe epilepsy

Epilepsia Open, EarlyView.
Abstract Objective Widespread cognitive deficits in temporal lobe epilepsy (TLE) are associated with macroscale brain structural changes. However, the correlation between the changes in the cortical morphological similarity of the TLE and gene expression remains unclear.

A rapid streamline-based extension of Tractfinder for white matter tract segmentation

Frontiers in Neuroimaging
Accurate delineation of white matter tracts is critical in the pre-operative assessment of paediatric brain tumour patients, where preservation of eloquent pathways directly influences surgical planning and functional outcomes.
