Examples of the stimuli used in this study.
Time runs from left to right with the upper row of each box depicting a regular sequence and the lower row an irregular one. I) color II) luminance III) letters IV) numbers.
Figure 2.
Glass brain projections to show the areas of activation produced by the comparison of Irregular vs. Regular sequences.
Figure 3.
Brain activity shown as glass-brain projections for the contrasts Regular vs. Irregular, with parameter estimates for the hottest voxel of each area of activation shown above.
Figure 4.
Brain areas activated in the comparison Irregular vs. Regular, to show the area of confluence of activity in the frontal lobe of the right hemisphere (right).
Figure 5.
Plots to show the difference in parameter estimates for the hottest voxel in the contrast of Irregular vs Regular obtained for each submodality.
The lower left panel shows the same for the region of overlap as identified by a conjunction of all 4 contrasts, and the lower right panel is a glass-brain projection to show the region of overlap. The equivalent conjunction analysis of Regular vs. Irregular did not show any common area to be active. All effects shown here are significant at p<0.001, uncorrected.
