The Teen Brain: Insights from Neuroimaging

Mean volume by age in years for males (N = 475 scans) and females (N = 354 scans). Middle lines in each set of three lines represent mean values; upper and lower lines represent upper and lower limits of 95% confidence intervals. Arrows indicate point of peak volume. All curves differed significantly between males and females in height and shape with the exception of lateral ventricles, in which only height was different, and mid-sagittal area of the corpus callosum, in which neither height nor shape was different. (a) Total brain volume, (b) gray matter volume, (c) white matter volume, (d) lateral ventricle volume, (e) mid-sagittal area of the corpus callosum, and (f) caudate volume.

Gray matter subdivisions: (a) frontal lobe, (b) parietal lobe, (c) temporal lobe, and (d) occipital lobe.
