Figure 6.

Amplitude of stimulus-evoked responses does not correlate with amplitude of slow endogenous fluctuations across 5-min fMRI runs. The amplitude at the stimulus frequency was normalized by subtracting the amplitude of nonstimulus frequency bands on either side of the stimulus frequency band to estimate the strength of the stimulus-evoked response on each attention-to-wedge run. Across runs, this measure of stimulus-evoked response amplitude was not significantly correlated with the magnitude of slow endogenous fluctuations at nonstimulus frequencies in any cortical area.
