The human body. Part 5, Brain power.

The fifth in a 7-part series in which Robert Winston looks in detail at the life of the human body in chronological order from birth to death. This part focuses on the human brain. Winston begins by looking at the evolution of our brains, then 3-D animated diagrams attempt to show how our neuronal networks are wired and effective. Amusingly, Winston drinks two bottles of red wine to show what happens to his mental reactions and thought processes. The complexity of our senses is covered, such as the sensitivity of touch. Our ability to categorise and our short- and long-term memories are explored, with examples from our evolution and everyday lives; Dominic O Brian, memory expert, is shown at work and describes how he has trained his memory so effectively. The importance of consciousness is covered as our social behaviours and politics.
