Diagram depicting a trial sequence for the real motion, ILM, and reverse ILM conditions.
Figure 2.
Behavioural data as a function of flash location and experimental condition.
Panel A) shows Percept scores and B) Decision Times. Error bars indicate +/− 1 SEM. ILM: illusory line motion.
Figure 3.
Activations for each of the three motion conditions superimposed onto the population-average landmark- and surface-based (PALS) standard brain (voxel threshold pcorr<0.05 FWE, k>20).
ACC: anterior cingulate cortex, AIC: anterior insular cortex, DLPFC: dorsolateral prefrontal cortex, FEF: frontal eye field, ILM: illusory line motion, IPS: intraparietal sulcus, PCC: posterior cingulate cortex, SMA: supplementary motor area.

Figure 4.
Differential brain activations (initial voxel threshold puncorr<0.001, cluster threshold pcorr<0.05 FWE) overlaid on the study-specific average of the normalised anatomical scans for the contrast “Illusory line motion > Real motion” (A), the contrast “Illusory line motion > Reverse illusory line motion” (B) and associated percentage signal change values (C).
Error bars indicate +/− 1 SEM. ACC: anterior cingulate cortex, ILM: illusory line motion, L: left, R: right.
