Nuisance effects in inter-scan functional connectivity estimates before and after nuisance regression

Publication date: Available online 20 July 2019Source: NeuroImageAuthor(s): Alican Nalci, Wenjing Luo, Thomas T. LiuAbstractIn resting-state functional MRI, the correlation between blood-oxygenation-level-dependent (BOLD) signals across brain regions is used to estimate the functional connectivity (FC) of the brain. FC estimates are prone to the influence of nuisance factors including scanner-related artifacts and physiological modulations of the BOLD signal. Nuisance regression is widely performed...

Functional plasticity associated with language learning in adults

Publication date: Available online 20 July 2019Source: NeuroImageAuthor(s): Kshipra Gurunandan, Manuel Carreiras, Pedro M. Paz-AlonsoAbstractLearning a new language in adulthood is increasingly common and among the most difficult tasks attempted by adults. Adult language learners thus offer an excellent window into the nature of learning-dependent plasticity. The present functional magnetic resonance imaging (fMRI) study was aimed at characterising functional neuroplasticity in adults at different...

Combining multiple connectomes improves predictive modeling of phenotypic measures

Publication date: Available online 20 July 2019Source: NeuroImageAuthor(s): Siyuan Gao, Abigail S. Greene, R. Todd Constable, Dustin ScheinostAbstractResting-state and task-based functional connectivity matrices, or connectomes, are powerful predictors of individual differences in phenotypic measures. However, most of the current state-of-the-art algorithms only build predictive models based on a single connectome for each individual. This approach neglects the complementary information contained...
