Resting functional brain MRI - Brain MRI - Imaging - UK Biobank Assessment Centre

Description

Resting-state functional MRI (rfMRI) measures changes in blood oxygenation associated with intrinsic brain activity (i.e., in the absence of an explicit task or sensory stimulus). Derived phenotypic fields estimate the apparent connectivity between pairs of brain regions, as reflected in the presence of spontaneous co-fluctuations in signal (i.e., the appearance of a connection based on co-activity, as opposed to a structural tract from dMRI).
