Dissociable Intrinsic Connectivity Networks for Salience Processing and Executive Control
TLDR
Two distinct networks typically coactivated during functional MRI tasks are identified, anchored by dorsal anterior cingulate and orbital frontoinsular cortices with robust connectivity to subcortical and limbic structures, and an “executive-control network” that links dorsolateral frontal and parietal neocortices. Expand
Linear Systems Analysis of Functional Magnetic Resonance Imaging in Human V1
TLDR
Results from three empirical tests support the hypothesis that fMRI responses in human primary visual cortex (V1) depend separably on stimulus timing and stimulus contrast, and the noise in the fMRI data is independent of stimulus contrast and temporal period. Expand
Image‐based method for retrospective correction of physiological motion effects in fMRI: RETROICOR
  • G. Glover, Tie‐Qiang Li, D. Ress
  • Computer Science, Medicine
  • Magnetic resonance in medicine
  • 1 July 2000
TLDR
The RETROICOR method is found to perform well for both respiration‐ and cardiac‐induced noise without imposing spatial filtering on the correction. Expand
The Alzheimer's disease neuroimaging initiative (ADNI): MRI methods
TLDR
The approach taken in ADNI to standardization across sites and platforms of the MRI protocol, postacquisition corrections, and phantom‐based monitoring of all scanners could be used as a model for other multisite trials. Expand
Retinotopic organization in human visual cortex and the spatial precision of functional MRI.
TLDR
This work identified the borders between several retinotopically organized visual areas in the posterior occipital lobe and estimated the spatial resolution of the fMRI signal and found that signal amplitude falls to 60% at a spatial frequency of 1 cycle per 9 mm of visual cortex. Expand
Resting-State Functional Connectivity in Major Depression: Abnormally Increased Contributions from Subgenual Cingulate Cortex and Thalamus
TLDR
The findings provide cross-modality confirmation of PET studies demonstrating increased thalamic and subgenual cingulate activity in major depression and suggest that a quantitative, resting-state fMRI measure could be used to guide therapy in individual subjects. Expand
Deconvolution of Impulse Response in Event-Related BOLD fMRI1
  • G. Glover
  • Psychology, Medicine
  • NeuroImage
  • 1 April 1999
TLDR
Deconvolution may be effective in diminishing the hemodynamically imposed temporal blurring and may have potential applications in quantitating responses in eventrelated fMRI. Expand
Time–frequency dynamics of resting-state brain connectivity measured with fMRI
TLDR
It was observed that coherence and phase between the PCC and the anticorrelated network was variable in time and frequency, and statistical testing based on Monte Carlo simulations revealed the presence of significant scale-dependent temporal variability. Expand
Spiral‐in/out BOLD fMRI for increased SNR and reduced susceptibility artifacts
  • G. Glover, C. Law
  • Physics, Medicine
  • Magnetic resonance in medicine
  • 1 September 2001
TLDR
The use of spiral‐in trajectories that begin at the edge of k‐space and end at the origin, and spiral in/out trajectories in which a spiral‐ in readout is followed by a conventional spiral‐out trajectory are reported. Expand
Functional Specialization for Semantic and Phonological Processing in the Left Inferior Prefrontal Cortex
TLDR
Functional magnetic resonance imaging results suggest that a distinct region in the left inferior frontal cortex is involved in semantic processing, whereas other regions may subserve phonological processes engaged during both semantic and phonological tasks. Expand
