DOI: 10.1002/brb3.3541
Abstract: Using correlation tractography, this study aimed to find statistically significant correlations between white matter (WM) tracts in participants with obstructive sleep apnea (OSA) and OSA severity. We hypothesized that changes in certain WM tracts could… read more here.

DOI: 10.1002/cne.24115
Abstract: The isocortex of primates is disproportionately expanded relative to many other mammals, yet little is known about what the expansion of the isocortex entails for differences in cellular composition and connectivity patterns in primates. Across… read more here.

Active delineation of Meyer's loop using oriented priors through MAGNEtic tractography (MAGNET)

DOI: 10.1002/hbm.23399
Abstract: Streamline tractography algorithms infer connectivity from diffusion MRI (dMRI) by following diffusion directions which are similarly aligned between neighboring voxels. However, not all white matter (WM) fascicles are organized in this manner. For example, Meyer's… read more here.

DOI: 10.1002/hbm.24917
Abstract: Investigative studies of white matter (WM) brain structures using diffusion MRI (dMRI) tractography frequently require manual WM bundle segmentation, often called “virtual dissection.” Human errors and personal decisions make these manual segmentations hard to reproduce,… read more here.

DOI: 10.1002/hbm.25777
Abstract: The segmentation of brain structures is a key component of many neuroimaging studies. Consistent anatomical definitions are crucial to ensure consensus on the position and shape of brain structures, but segmentations are prone to variation… read more here.

DOI: 10.1002/hbm.26339
Abstract: Subcallosal cingulate gyrus (SCG) is a target of deep brain stimulation (DBS) for treatment-resistant depression. However, previous randomized controlled trials report that approximately 42% of patients are responders to this therapy of last resort, and… read more here.

DOI: 10.1002/hbm.26704
Abstract: Progressive apraxia of speech (PAOS) is a 4R tauopathy characterized by difficulties with motor speech planning. Neurodegeneration in PAOS targets the premotor cortex, particularly the supplementary motor area (SMA), with degeneration of white matter (WM)… read more here.

DOI: 10.1002/hbm.70042
Abstract: Despite substantial neuroscience research in the last decade revealing the claustrum's prominent role in mammalian forebrain organization, as evidenced by its extraordinarily widespread connectivity pattern, claustrum studies in humans are rare. This is particularly true… read more here.

Mapping connectomes with diffusion MRI: deterministic or probabilistic tractography?
Sign Up to like & getrecommendations! Published in 2019 at "Magnetic Resonance in Medicine"
DOI: 10.1002/mrm.27471
Abstract: Human connectomics necessitates high‐throughput, whole‐brain reconstruction of multiple white matter fiber bundles. Scaling up tractography to meet these high‐throughput demands yields new fiber tracking challenges, such as minimizing spurious connections and controlling for gyral biases.… read more here.
