Regions in Talairach space where BOLD signal intensity and reaction time were correlated during the combined angle and color discrimination. L = left, R = right.

^*This column indicates whether average activation in each cluster was positive, negative or not significantly different from zero (NS) in one-sample t-test. Numbers of brain regions correspond to those in the right segment of Fig. 6.
