Article Title: Correspondence of functional connectivity gradients across human isocortex, cerebellum, and hippocampus
Article Snippet: Briefly, this dataset includes 1139 participants ( M age = 21.24, SD age = 2.70, 467 males, 672 females) who had undergone one structural scan (T1-weighted multi-echo MPRAGE, 1.2 mm isotropic voxels) and two 6 min functional runs at wakeful rest (gradient-echo EPI sequence, 3 mm isotropic voxels) using 3 T Siemens Tim Trio Scanners.

Article Title: Shift-invariant rank-(L, L, 1, 1) BTD with 3D spatial pooling and orthonormalization: Application to multi-subject fMRI data
Article Snippet: The rank-(L, L, 1, 1) block term decomposition (BTD) model shows better separation performance for multisubject fMRI data by preserving the high-way structure of fMRI data than canonical polyadic decomposition (CPD).. However, multi-subject fMRI data are noisy and have high spatiotemporal variability.. To address these limitations, this paper proposes a novel 3D weighted spatial pooling preprocessing that compresses and smooths multi-subject fMRI data and assigns a higher weight to in-brain voxels but a lower weight to out-brain voxels.

Article Title: Clavulanic Acid-Mediated Increases in Anterior Cingulate Glutamate Levels are Associated With Decreased Cocaine Craving and Brain Network Functional Connectivity Changes
Article Snippet: Resting-state fMRI was performed using Siemens product Gradient-Echo EPI with multiband factor of 3.

Article Title: A critical assessment of data quality and venous effects in sub-millimeter fMRI
Article Snippet: Functional data were collected at 7T using gradient-echo EPI at 0.8-mm isotropic resolution with partial-brain coverage (84 oblique slices covering occipitotemporal cortex, slice thickness 0.8 mm, slice gap 0 mm, field-of-view 160 mm (FE) × 129.6 mm (PE), phase-encode direction inferior-superior (F >> H in Siemens’ notation), matrix size 200 × 162, TR 2.2 s, TE 22.4 ms, flip angle 80°, echo spacing 1.00 ms, bandwidth 1136 Hz/pixel, partial Fourier 6/8, in-plane acceleration factor (iPAT) 3, multiband slice acceleration factor 2).

Article Title: Estimating dynamic individual coactivation patterns based on densely sampled resting-state fMRI data and utilizing it for better subject identification.
Article Snippet: As a complex dynamic system, the brain exhibits spatially organized recurring patterns of activity over time.. Coactivation patterns (CAPs), which analyzes data from each single frame, have been utilized to detect transient brain activity states recently.. However, previous CAP analyses have been conducted at the group level, which might neglect meaningful individual differences.

Article Title: A temporal decomposition method for identifying venous effects in task-based fMRI
Article Snippet: Functional data for Experiments E1 and E2 were collected at 7T using gradient-echo EPI at 0.8-mm isotropic resolution with partial-brain coverage (84 oblique slices covering occipitotemporal cortex, slice thickness 0.8 mm, slice gap 0 mm, field-of-view 160 mm (FE) × 129.6 mm (PE), phase-encode direction inferior-superior (F ≫ H in Siemens’ notation), matrix size 200 × 162, TR 2.2 s, TE 22.4 ms, flip angle 80°, echo spacing 1 ms, bandwidth 1136 Hz/pixel, partial Fourier 6/8, in-plane acceleration factor (iPAT) 3, multiband slice acceleration factor 2).

Article Title: A temporal decomposition method for identifying venous effects in task-based fMRI
Article Snippet: Functional data for Experiment E4 were collected at 3T using gradient-echo EPI at 2.4-mm isotropic resolution with partial-brain coverage (30 slices, slice thickness 2.4 mm, slice gap 0 mm, field-of-view 192 mm (FE) × 192 mm (PE), phase-encode direction anterior-posterior (A ≫ P in Siemens’ notation), matrix size 80 × 80, TR 1.1 s, TE 30 ms, flip angle 62°, echo spacing 0.55 ms, bandwidth 2232 Hz/pixel, no partial Fourier, no in-plane acceleration, multiband slice acceleration factor 2).

Article Title: Correspondence of functional connectivity gradients across human isocortex, cerebellum, and hippocampus.
