The Human Body S01 E05 Brain Power

This programme examines the human brain, the most complicated object in the known universe. Cameras capture a single brain cell, magnified 10,000 times, as it fires an electrical impulse. Scanners show the complex activity required for simple pastimes. And, in the name of science, Professor Robert Winston shows how the brain's delicate balance of chemicals can be disrupted by a few glasses of wine.
