Figure 8

Comparison of the strengths of suppression at different stimulus contrasts. Bars on the left indicate percent signal change in BOLD response for the central region of the stimulus at three different contrast levels in Experiment 2. Gray bars correspond to the unifocal, and white bars to the multifocal condition. Bars on the right are suppression indices for corresponding stimulus contrasts. Data is pooled over all eight subjects, and error bars denote SEM. Asterisks indicate statistically significant differences in BOLD signal change (P < 0.05).
