Figure 8.

Negative psychophysiological interaction (PPI) effects of the right middle occipital gyrus (RMOG) in the visual checkerboard task. The RMOG seed is illustrated in the left most column. Model numbers correspond to the five PPI models in Figure 3. Please note that model 1 did not generate statistically significant results, and model 3 and 4 produced exactly the same results. The results were first thresholded at P < 0.001, and clusters were identified using cluster‐level false discover rate (FDR) at P < 0.05. Z values and seed coordinates are in MNI (Montreal neurological institute) space. [Color figure can be viewed at http://wileyonlinelibrary.com]
