Volume and response amplitudes of object selective activations in VTC. (A) The total volume of activated voxels for cars > scrambled, or abstract objects > scrambled at five different thresholds (10−2 to 10−6, shown as minus logarithm base 10, uncorrected). Light red: adolescents (ages 12–16 years, n = 14); dark red: adults (ages 18–40 years, n = 11). (B) Percent signal change for object selective voxels. We defined in each subject object selective voxels in the VTC using the contrast: cars and abstract objects > scrambled, P < 10−3, from run 1 data. Object selective voxels were found in all subjects from run 1 data. Signal amplitudes were extracted from these voxels in run 2 data. We calculated the average response across each subject's voxels and then averaged across subjects. Error bars show group SEM (11 adults and 14 adolescents). Asterisks indicate significantly higher than scrambled (P < 0.05, t-test across subjects) and are corrected for multiple comparisons using Bonferroni correction.
