Figure 6. Outline of the reciprocal analysis strategy carried out with simultaneous EEG-fMRI, investigating differential effects of primary task visual working memory load on secondary task fundamental auditory processing.

fMRI = functional magnetic resonance imaging, WM = working memory, ERP = event-related potential, ANCOVA = analysis of covariance, BOLD = blood oxygenation level dependent, ROI = region-of-interest, PPI = psychophysiological interaction.
