A Cerebellar Partitioning Method Using Spectral Clustering With Optimized Nonlinear Functional Connectivity

open access: yesHuman Brain Mapping, Volume 46, Issue 10, July 2025.
By incorporating nonlinear order‐preserving transformations and spatial constraints to optimize the distribution of functional connectivity (FC) in the cerebellum, the cerebellar partitioning obtained using spectral clustering provides stable and reliable results in terms of reproducibility, spatial continuity, and signal homogeneity.

Human Connectome Project (Hcp)

open access: yes, 2016
This project deals with the nervous system and its function in brain. Here connectome means the microscopic neural connectivity and its mapping between all the neurons present in the brain which further represents their graphical representation on the visual screen also which will further help us to zoom into a region to explore the cells and the ...

Dynamic Functional Connectivity Between Amygdala and Cognitive Control Network Predicts Delay Discounting in Older Adolescents

open access: yesHuman Brain Mapping, Volume 46, Issue 10, July 2025.
This study investigates brain mechanisms behind reward sensitivity in adolescents. Findings indicate that dynamic functional connectivity between the left amygdala and the cognitive control network predicted delay discounting in older adolescents, but not in younger adolescents or adults.

Unraveling Hierarchical Brain Dysfunction in Major Depressive Disorder: A Multimodal Imaging and Transcriptomic Approach

open access: yesHuman Brain Mapping, Volume 46, Issue 10, July 2025.
Dysfunctional hierarchy in major depressive disorder (MDD) features decreased SDI in regions linked to high‐order cognitive functions, like the prefrontal, parietal, and orbitofrontal cortices. Conversely, areas related to low‐level sensory‐motor functions, the somatosensory cortex, showed increased SDI in MDD.

White Matter Geometry Confounds Diffusion Tensor Imaging Along Perivascular Space (DTI‐ALPS) Measures

open access: yesHuman Brain Mapping, Volume 46, Issue 10, July 2025.
Our findings reveal that the DTI‐ALPS index, a proposed marker of glymphatic function, is strongly influenced by white matter geometry—including fiber crossings, dispersion, and undulations. These findings challenge the specificity of ALPS and highlight the need for careful interpretation in studies linking ALPS metrics to glymphatic function ...

Limitations of Correlation Coefficients in Research on Functional Connectomes and Psychological Processes

open access: yesHuman Brain Mapping, Volume 46, Issue 10, July 2025.
This study highlights the limitations of the correlation coefficient in functional connectome and psychological process modeling, emphasizing its inability to capture nonlinear relationships, address systematic biases, and ensure comparability. By proposing comprehensive evaluation metrics and baseline comparisons, it offers practical guidance for ...

MPRAGElike: A novel approach to generate T1w images from multi‐contrast gradient echo images for brain segmentation

open access: yesMagnetic Resonance in Medicine, Volume 94, Issue 1, Page 134-149, July 2025.
Abstract Purpose Brain segmentation and multi‐parameter mapping (MPM) are important steps in neurodegenerative disease characterization. However, acquiring both a high‐resolution T1w sequence like MPRAGE (standard input to brain segmentation) and an MPM in the same neuroimaging protocol increases scan time and patient discomfort, making it difficult to

A Subtracted‐Added‐Divided Inversion Recovery (dSIR) Approach to Visualise the Effects of Microstructure on T1 Contrast in Human White Matter

open access: yesNMR in Biomedicine, Volume 38, Issue 7, July 2025.
TI images collected with short (300ms/600ms, 3T/7T) and long TI (600ms/1000ms, 3T/7T) were processed using the dSIR approach to visualise effects of white matter (WM) microstructure on T1 contrast. Short T1 resulting from relaxation anisotropy in WM tracts with close to perpendicular orientation to B0 was visualised by excellent dSIR contrast against ...
