The authors note that on page 14900, right column, first paragraph, lines 1-5, the following statement appeared incorrectly: "In the group with frontal lesions (n = 44), only MD lesion volume was retained as a significant predictor (r = −0.40; P = 0.004) (Fig. 3A ). The correlation between behavioral deficit and MD lesion volume also remained significant if non-MD lesion volume was first partialled out (r = −0.27; P = 0.037)." The statement should instead appear as: "In the group with frontal

However, the correlation was no longer significant if non-MD lesion volume was first partialled out (r = −0.19; P = 0.106). Accordingly, MD lesion volume was not retained as a significant predictor in the multiple regression." "MD" refers to the multiple demand regions (1). This error does not affect the conclusions of the article.
