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

Beyond Broca and Wernicke: Epilepsy surgery in the language areas

Epileptic Disorders, EarlyView.
Abstract Epilepsy surgery in language areas is challenged by the intricacies of presurgical workup and surgical planning. In recent decades, the view of language‐related circuitry has shifted from being localized in a few cortical centers to a distributed, dynamically interconnected system, increasing complexity.

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 ...

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).

Tensor kernels for simultaneous fiber model estimation and tractography [PDF]

Magnetic Resonance in Medicine, 2010
AbstractThis paper proposes a novel framework for joint orientation distribution function estimation and tractography based on a new class of tensor kernels. Existing techniques estimate the local fiber orientation at each voxel independently so there is no running knowledge of confidence in the measured signal or estimated fiber orientation.

Picture naming: Stereoelectroencephalography and connectivity insights

Epilepsia, EarlyView.
Abstract Objective This study investigates the neural substrates of picture naming (PN) using stereoelectroencephalographic (SEEG) stimulations and evaluates the contribution of white matter (WM) fascicles related to the basal temporal language area (BTLA) to the broader functional PN network.

The Superior Fronto-Occipital Fasciculus in the Human Brain Revealed by Diffusion Spectrum Imaging Tractography: An Anatomical Reality or a Methodological Artifact?

Frontiers in Neuroanatomy, 2017
The existence of the superior fronto-occipital fasciculus (SFOF) in the human brain remains controversial. The aim of the present study was to clarify the existence, course, and terminations of the SFOF.

Diffusion spectrum imaging of patients with middle cerebral artery stenosis

NeuroImage: Clinical, 2022
Objective: We aimed to detect microstructural changes in the brains of patients with unilateral middle cerebral artery (MCA) stenosis and to assess the integrity of the fiber structure and the small-world networks using diffusion spectrum imaging (DSI ...

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 ...
