Volume of face selective activations defined using either man or boy faces. (A) Activation maps for boy selective voxels (boy faces > cars and abstract objects, P < 10−3), red, man selective voxels (man faces > cars and abstract objects, P < 10−3), green, and overlapping voxels (yellow). Data are shown for a representative adolescent brain. (B) Average volume of the cluster of voxels defined by the same contrasts as in (A). Error bars show group SEM. (C) The volume of all man selective or boy selective voxels in the VTC regardless of contiguity at five different statistical thresholds (10−2 to 10−6, uncorrected). Light red: adolescents (ages 12–16 years, n = 14); dark red: adults (ages 18–40 years, n = 11). Error bars show group SEM. Large asterisks indicate significantly larger volume in adults vs. adolescents (P < 0.02, F-test repeated measures ANOVA).
