Figure 8.
Correlation between behavioral performance and amplitude of fluctuations across the frequency spectrum. In all topographically organized areas, negative correlations between performance and endogenous fMRI signal fluctuations tended to be weaker at the slowest nonstimulus frequencies (<0.015 Hz) compared with higher nonstimulus frequencies. Stimulus frequency (0.029 Hz) and associated harmonics (0.059 and 0.088 Hz) are indicated with arrows. Error bars represent SEMs across participants.
