Is the internet overloading our brains?

Joined by Facebook founder Mark Zuckerberg, Bill Gates, Al Gore and the neuroscientist Susan Greenfield, Aleks examines the popularity of social networks such as Facebook.

How are they changing our relationships? Do they bring us together - or do they end up leaving us more isolated?

And, in a ground-breaking test at University College London, Aleks investigates how the Web may be distracting and overloading our brains.
