Of course, this lack of power is driven in large part by the great expense associated with collecting fMRI data16. Even relatively small studies can cost several tens of thousands of dollars, and the funding system throughout much of the world is not generally set up to enable the routine ...
Panel a is a subset of the participants who agreed to fMRI, analyzed by a paired t-test.shown, and panels b-e are displayed as mean and 95% confidence intervals with analysis performed by Linear Mixed Effects Analysis with multiple comparisons and false discovery rate correction (* p adj....
The benefit of small animal imaging is directly linked to the validity and reliability of the collected data. If the data (regardless of the modality used) are not reproducible and/or reliable, then the outcome of the data is rather questionable. Therefore, standardization of the use of small ...
(field 25742) and Mean rfMRI head motion (field 25741) (see Supplementary Tables7–9for further details). Missing values for MRI head motion indicators were imputed using the R package mice with the predictive mean matching method53based on all covariates. A meta-analysis was performed of the...
(significanceα < 0.0083, after Bonferroni correction). The alternative hypothesis, and the respectivep-values for each test are reported in Table5B. The alternative hypothesis was defined as the judgment variable distribution median being greater in the ‘higher’ anxiety group than the ‘lower...
we acquired resting-state fMRI from a cohort of university-level athletes with concussion at acute injury, RTP and 1 year post-RTP. A large normative cohort of athletic controls without recent concussion was also imaged. We examined small-world measures of global and local efficiency over the re...

For each participant, the T1-weighted images were manually skull-stripped and segmented into grey matter, white matter, and cerebral spinal fluid (CSF) masks, which were then co-registered to their fMRI space. Total brain volume was calculated by adding the gray and white matter volumes of ...
