A meta-analytic approach to mapping co-occurrent grey matter volume increases and decreases in psychiatric disorders

NeuroImage, 2020
Numerous studies have investigated grey matter (GM) volume changes in diverse patient groups. Reports of disorder-related GM reductions are common in such work, but many studies also report evidence for GM volume increases in patients.

Lidocaine patch (5%) is no more potent than placebo in treating chronic back pain when tested in a randomised double blind placebo controlled brain imaging study

Molecular Pain, 2012
Background The 5% Lidocaine patch is used for treating chronic neuropathic pain conditions such as chronic back pain (CBP), diabetic neuropathy and complex regional pain syndrome, but is effective in a variable proportion of patients.

Brain‐Wide Spatiotemporally Distinct Traveling Waves Drive Anxiety‐Like Behaviors in Mice

Advanced Science, EarlyView.
J.Liu et al. reveal the complete propagation dynamics of cortical traveling waves, from local circuitry initiation to long‐range propagation, and identify their functional relevance in modulating anxiety‐like behaviors and underlying cellular neuroplasticity in mice.

Encoding and decoding in fMRI [PDF]

NeuroImage, 2011
Over the past decade fMRI researchers have developed increasingly sensitive techniques for analyzing the information represented in BOLD activity. The most popular of these techniques is linear classification, a simple technique for decoding information about experimental stimuli or tasks from patterns of activity across an array of voxels.

Calibrated fMRI

NeuroImage, 2012
Functional magnetic resonance imaging with blood oxygenation level-dependent (BOLD) contrast has had a tremendous influence on human neuroscience in the last twenty years, providing a non-invasive means of mapping human brain function with often exquisite sensitivity and detail. However the BOLD method remains a largely qualitative approach.

Aging and the Spectral Properties of Brain Hemodynamics

Advanced Science, EarlyView.
As the brain ages, its metabolic demands decline—but not uniformly. Here, spectral slope flattening of resting‐state fMRI signals is proposed as a potential biomarker of pathologic brain aging. A subset of older adults diverges from youthful spectral and metabolic patterns, with changes linked to frontal white matter pathology and regional loss of ...

Pre- and post-therapy functional MRI connectivity in severe acute brain injury with suppression of consciousness: a comparative analysis to epilepsy features

Frontiers in Neuroimaging
Severe acute brain injury (SABI) with suppressed consciousness is a major societal burden, with early prognosis being crucial for life-and-death treatment decisions.

fMRI adaptation revisited [PDF]

Cortex, 2016
Adaptation has been widely used in functional magnetic imaging (fMRI) studies to infer neuronal response properties in human cortex. fMRI adaptation has been criticized because of the complex relationship between fMRI adaptation effects and the multiple neuronal effects that could underlie them.
