WebRecent years have seen an increase in the use of multi-echo fMRI designs by cognitive neuroscientists. Acquiring multiple echoes allows one to increase contrast-to-noise; reduce signal dropout and thermal noise; and identify nuisance signal components in BOLD data. At the same time, multi-echo acquisitions increase data processing complexity and may … WebJun 30, 2016 · Introduction. Blood-oxygen-level dependent (BOLD) contrast is the primary signal used in functional MRI (fMRI) studies of brain function. However, BOLD is not a direct measure of neuronal activity, but rather a …
