Complex-Valued Time-Series Correlation Increases Sensitivity in FMRI Analysis

Abstract Purpose To develop a linear matrix representation of correlation between complex-valued (CV) time-series in the temporal Fourier frequency domain, and demonstrate its increased sensitivity over correlation between magnitude-only (MO) time-series in functional MRI (fMRI) analysis.
