US president Barack Obama has announced a $100 million plan to map the billions of neurons at work in the human brain.
The brain is the least understood part of the human body.
We have a rudimentary idea of how it works, and why things go wrong, but the bigger questions like how we generate thoughts are still a mystery.
Answering them will be a big task to say the least.
"Of course, none of this will be easy. If it was, we would already know everything there was about how the brain works, and presumably my life would be simpler here," Mr Obama said.
"But think about what we could do once we do crack this code."
