Excerpt:

"The teenage brain is malleable to a remarkable degree: during adolescence the vast number of synapses is ruthlessly reduced or "pruned", leaving a system of thinking and behaviour that has a rigidity not seen in earlier years: "Teenagers have plastic brains which can wire themselves up not according to a genetic blueprint but in the light of experience . . . The teenage brain is a 'behaviour establishing machine' leaving adulthood as nothing more than a slow decline into mental and emotional inflexibility," he writes."
