Teenage Brain undergoes a radical re-development seen in the rest of the human body.
With the advent of brain scans (magnetic resonance imaging technology), the neuroscientist is able to study the living brain in the real time of an adolescent.
2 main changes
1. Growth of fatty insulation around the electrically charged neurons (the message-transmitting cells). This extra insulation increases the speed of transmission a hundred fold.
2. "Synaptic Pruning"- means in the early years of growth, the pruning back of critical connections or synapses that link neurons to one another.
Dr. Sarah Jayne Blakemore, a cognitive neuroscientist at university college London, says that teenagers are more self-reflective than prepubescent children.
