20 June 2013 Last updated at 19:02 BST
Researchers have created the first high-resolution 3D digital model of the human brain which they have called "Big Brain".
The reconstruction shows the brain's anatomy in microscopic detail, enabling researchers to see features smaller than a strand of hair.
It will be made freely available to neuroscientists to help them in their research.
The model has been published in the journal Science.
Science correspondent Pallab Ghosh explains how Big Brain was created and what it shows.
