This picture of the human brain reminds us of a distant galaxy far, far away

Does this picture of human brain activity remind you of distant galaxies? It should do: the human brain is made up of a hundred billion cells, and there are as many connections between them in a cubic centimetre of brain tissue as there are stars in the Milky Way.

Investigators are only now beginning to understand the way those connections work and how they shape our perceptions of the world.

“The brain has remarkable properties,” says American neuroscientist David Eagleman. “Before the age of eight, it’s possible to remove half of the brain and the other half will take on the missing functions. It’s only three pounds of Jell-O material made up of hundreds of billions of dumb little cells running their own little program. But get enough of those doing their own thing and you have the human mind.”  

The Brain with David Eagleman airs Thursday at 9:00pm on BBC4
