Brain maturation from ages 5 to 20

Description
Selected slides from MRI scans that tracked brain maturation from ages 5 to 20. Grey matter (red) diminishes as the brain matures because of synaptic pruning and myelination (blue). Notice that the region at the front of the brain (the prefrontal cortex that is associated with higher mental functioning) matures last.
