Has a trillion brain-cells, including:

100 billion active nerve-cells.

900 billion other cells that "glue," nourish and insulate the active cells.

Can grow up to 20,000 "branches" on every one of those 100 billion neurons.

Has four distinct brains in one: An instinctive brain. A "balancing brain". An emotional brain. And your amazing cortex.

Has two sides that work in harmony: Your left "academic" brain. Your right "creative" brain. Runs a "telephone exchange" that shuttles millions of messages a second between the left and right sides. Has many different "intelligence centers". Operates on at least four separate wavelengths. Controls a transmission system that flashes chemical-electrical messages instantly to every part of your body. And it holds the key to your own personal learning revolution.
