Reconstruction of the arcuate fasciculus for surgical planning in the setting of peritumoral edema using two-tensor unscented Kalman filter tractography

NeuroImage: Clinical, 2015
Background: Diffusion imaging tractography is increasingly used to trace critical fiber tracts in brain tumor patients to reduce the risk of post-operative neurological deficit.

The role of spatial embedding in mouse brain networks constructed from diffusion tractography and tracer injections

NeuroImage, 2021
Diffusion MRI tractography is the only noninvasive method to measure the structural connectome in humans. However, recent validation studies have revealed limitations of modern tractography approaches, which lead to significant mistracking caused in part

Reduced structural connectivity between left auditory thalamus and the motion-sensitive planum temporale in developmental dyslexia

, 2018
Developmental dyslexia is characterized by the inability to acquire typical reading and writing skills. Dyslexia has been frequently linked to cerebral cortex alterations; however recent evidence also points towards sensory thalamus dysfunctions ...

Open diffusion magnetic resonance imaging and connectivity data for epilepsy and surgery: The IDEAS II release

Epilepsia, EarlyView.
Abstract Objective Epileptic seizures are generated in cerebral networks that propagate ictal and interictal activity. The structure of cerebral networks underpinning epileptic activity can be inferred from diffusion‐weighted magnetic resonance imaging (DWI).

Accelerated forgetting of contextual details due to focal medio-dorsal thalamic lesion [PDF]

, 2014
Effects of thalamic nuclei damage and related white matter tracts on memory performance are still debated. This is particularly evident for the medio-dorsal thalamus which has been less clear in predicting amnesia than anterior thalamus changes.

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 ...

Quantitative analysis of fiber tractography in cervical spondylotic myelopathy [PDF]

The Spine Journal, 2013
Diffusion tensor fiber tractography is an emerging tool for the visualization of spinal cord microstructure. However, there are few quantitative analyses of the damage in the nerve fiber tracts of the myelopathic spinal cord.The aim of this study was to develop a quantitative approach for fiber tractography analysis in cervical spondylotic myelopathy ...

Exploring the Anatomical Basis of Effective Connectivity Models with DTI-Based Fiber Tractography

International Journal of Biomedical Imaging, 2008
Diffusion tensor imaging (DTI) is considered to be a promising tool for revealing the anatomical basis of functional networks. In this study, we investigate the potential of DTI to provide the anatomical basis of paths that are used in studies of ...

Patient‐Reported Feedback Suggests an Alternative Sweet Spot for Deep Brain Stimulation Programming in Essential Tremor

Movement Disorders, EarlyView.
(1) To sample subjective patient rating using the Visual Analogue Scale (VAS), random stimulation parameters were presented to the study subjects. (2) Next, corresponding volumes of tissue activated (VTA) were generated and paired with VAS values.
