Functional brain connectivity in resting-state fMRI using phase and magnitude data.
Chen Z, Caprihan A, Damaraju E, Rachakonda S, Calhoun V. Chen Z, et al. J Neurosci Methods. 2018 Jan 1;293:299-309. doi: 10.1016/j.jneumeth.2017.10.016. Epub 2017 Oct 18. J Neurosci Methods. 2018. PMID: 29055719
BACKGROUND: The output of BOLD fMRI consists of a pair of magnitude and phase components. While the magnitude data has been widely accepted for brain function analysis, we can also make use of the phase data (unwrappe …
