Note that results are not shown for Left POS as there were no significant effects. Non-significant (P > 0.05) statistics are not presented to improve clarity, but are available from the authors by request. I, II, and III indicate sulcogyral pattern types I, II and III, respectively. 0, 1 and 2 indicate zero, one and two POS, respectively.

Post hoc tests are shown at P < 0.05 (^aP < 0.1).

^b Significant finding only for females.
