Figure 7.
Correlation between performance and fMRI amplitude at stimulus and nonstimulus frequencies. (A) Across 5-min runs, no topographically organized area showed a significant correlation between amplitude at the stimulus frequency and the percentage of wedge targets that were correctly detected. (B) Behavioral performance was significantly negatively correlated with amplitude of fMRI fluctuations at nonstimulus frequencies. Open circles: individual participant data from 3T scanner; filled circles: individual participant data from 4T scanner. Error bars represent SEMs across participants.
