23c, p24', a24') (Vogt et al. 1995). Of those regions, areas 4 (left hemisphere) and p24' (right hemisphere) were also significantly different within the HCP young adults (P < 0.05) (Table 2 and Figure 4). However, with respect to areas 4, 23c, and p24', the corresponding age effects (βage) measured in the NCANDA adolescent group were 1.3 to 2.9 times higher than those measured in the HCP young adults (Table 2 and Figure 4). For young adults, area 23c (right hemisphere) showed a trend towards an age effect (P = 0.056) (Table 2).
