Table 4.

Average BOLD response (high load 6-dot vs. low load 2-dot working memory) and cortical thickness in each region of interest and correlation between BOLD and cortical thickness (r and p). The left frontal pole and and right fusiform show significant positive correlations (p < .05); however, these findings do not surpass Type I error correction.
