Longitudinal Scalar-on-Function Regression with Application to Tractography Data [PDF]

, 2012
We propose a class of estimation techniques for scalar-on-function regression in longitudinal studies where both outcomes, such as test results on motor functions, and functional predictors, such as brain images, may be observed at multiple visits.

Mental Scene and Memory Construction and the Hippocampus

Hippocampus, Volume 36, Issue 6, November 2026.
ABSTRACT A neurocomputational theory of scene and memory construction during memory recall, prospective thinking, and autobiographical memory is described. The theory describes the nature of the representation of scenes using spatial view cells in a continuous attractor network in the medial parahippocampal cortex, and how the location in the scene ...

Regularized Joint Reconstruction and Slab Combination for Accelerated Three‐Dimensional Multi‐Slab Diffusion‐Weighted Imaging Using Multi‐Scale Energy Models

Magnetic Resonance in Medicine, Volume 96, Issue 5, Page 2321-2335, November 2026.
ABSTRACT Purpose To jointly reconstruct high‐resolution diffusion‐weighted volumes and eliminate slab‐boundary artifacts while preserving fine anatomical detail from undersampled 3D multi‐slab k‐space acquisitions. Methods A bilinear forward model was formulated to describe the 3D multi‐slab acquisition, treating the image volume and slab excitation ...

Comparison of 9 Tractography Algorithms for Detecting Abnormal Structural Brain Networks in Alzheimer’s Disease

Frontiers in Aging Neuroscience, 2015
Alzheimer’s disease (AD) involves a gradual breakdown of brain connectivity, and network analyses offer a promising new approach to track and understand disease progression. Even so, our ability to detect degenerative changes in brain networks depends on

Evaluation of diffusion-tensor imaging-based global search and tractography for tumor surgery close to the language system. [PDF]

PLoS ONE, 2013
Pre-operative planning and intra-operative guidance in neurosurgery require detailed information about the location of functional areas and their anatomo-functional connectivity.

DDSurfer: A Weakly‐Supervised Dual‐Stream Deep Learning Framework for Cortical Surface Reconstruction From Diffusion MRI

Advanced Science, Volume 13, Issue 56, 9 October 2026.
DDSurfer reconstructs cortical surfaces directly from diffusion MRI without requiring T1‐weighted scans. By fusing complementary microstructural features and learning diffeomorphic deformations, it efficiently generates accurate white matter and pial surfaces, improving geometric fidelity and morphometric reliability across datasets for robust surface ...

Use of probabilistic tractography to provide reliable distinction of the motor and sensory thalamus for prospective targeting during asleep deep brain stimulation.

, 2022
OBJECTIVE: Accurate electrode placement is key to effective deep brain stimulation (DBS). The ventral intermediate nucleus (VIM) of the thalamus is an established surgical target for the treatment of essential tremor (ET).

Probabilistic streamline q-ball tractography using the residual bootstrap

NeuroImage, 2008
Q-ball imaging has the ability to discriminate multiple intravoxel fiber populations within regions of complex white matter architecture. This information can be used for fiber tracking; however, diffusion MR is susceptible to noise and multiple other sources of uncertainty affecting the measured orientation of fiber bundles.

Probabilistic atlases of default mode, executive control and salience network white matter tracts: An fMRI-guided diffusion tensor imaging and tractography study

Frontiers in Human Neuroscience, 2015
Diffusion tensor imaging (DTI) is a powerful MRI technique that can be used to estimate both the microstructural integrity and the trajectories of white matter pathways throughout the central nervous system.

Investigating the Neural Bases of Egocentric Spatial Reference Frame After Right‐Hemisphere Stroke: Brain Lesions and Disconnectome Analyses of Subjective Straight Ahead and Longitudinal Body Axis Misperception

Human Brain Mapping, Volume 47, Issue 14, October 1, 2026.
The figure illustrates distinct neural substrates for egocentric body reference after right‐hemisphere stroke. SSA distortions are linked to right fronto‐parietal lesions and posterior corpus callosum disconnections, whereas LBA distortions involve temporo‐occipital damage and inferior longitudinal fasciculus disconnections, emphasising a functional ...
