Estimates of functional connectivity derived from resting-state magnetic resonance imaging (rs-fMRI) are sensitive to artefacts caused by in-scanner head motion. This susceptibility has motivated the development numerous denoising methods designed mitigate motion-related artefacts. Here, we compare popular retrospective rs-fMRI methods, such as regression motion parameters and mean white matter (WM) cerebrospinal fluid (CSF) (with without expansion terms), aCompCor, volume censoring (e.g.,...
Context: Neurobiological models of obsessive-compulsive disorder (OCD) emphasize disturbances in the function and connectivity brain corticostriatal networks, or "loops."Although neuroimaging studies patients have supported this network model OCD, very few applied measurements that are sensitive to features.Objective: Using resting-state functional magnetic resonance imaging, we tested hypothesis OCD is associated with primarily ventral regions, measured from coherent spontaneous...
Context: Cannabis is the most widely used illicit drug in developed world.Despite this, there a paucity of research examining its long-term effect on human brain.Objective: To determine whether heavy cannabis use associated with gross anatomical abnormalities 2 cannabinoid receptor-rich regions brain, hippocampus and amygdala.Design: Cross-sectional design using high-resolution (3-T) structural magnetic resonance imaging.Setting: Participants were recruited from general community underwent...
The notion of a “default mode brain function” has taken on certain relevance in human neuroimaging studies and relation to network lateral parietal midline cortical regions that show prominent activity fluctuations during passive imaging states, such as rest. In this study, we perform three fMRI experiments demonstrate consistency specialization the default network. Correlated are identified ( i ) eyes-closed spontaneous rest, ii activation by moral dilemma, iii deactivation Stroop task...
Cannabis use typically begins during adolescence and early adulthood, a period when cannabinoid receptors are still abundant in white matter pathways across the brain. However, few studies to date have explored impact of regular cannabis on structure, with no previous examining its axonal connectivity. The aim this study was examine fibre brain for evidence microstructural alterations associated long-term test whether age is severity any change. To end, diffusion-weighted magnetic resonance...
The human cerebral cortex is a complex network of functionally specialized regions interconnected by axonal fibers, but the organizational principles underlying cortical connectivity remain unknown. Here, we report evidence that one such principle for functional networks involves finding balance between maximizing communication efficiency and minimizing connection cost, referred to as optimization cost-efficiency. We measured spontaneous fluctuations blood oxygenation level-dependent signal...
