Inside the human body. Part 3, Building your brain.

The third in a four-part series, presented by Michael Mosley, in which CGI footage is used to show the workings of the human body. In this part, Mosley traces our neurological development from birth to adulthood, revealing that it takes twenty years for the human brain to mature. We see the world through the perspective of a newborn and that of a girl with neurological difficulties. Moken sea gypsy children train themselves to see clearly underwater and a Vietnamese girl can speak eleven languages fluently. Different phases of emotional development, particularly between the ages of eleven and twenty, are discussed as these are times when many of the earlier brain connections are lost in the process of remodelling and growing up.
