Computers will one day match our own mental agility; learning, navigating and performing complex interactions all on scant power. But getting to that point will require neuroscientists and engineers to reverse engineer our least understood organ—the brain.
The brain has 100 billion neurons. Now scientists can map where they go.
Signals zip through the brain's wiring. Voltage-sensing proteins let scientists watch.
The brain contains many distinct parts. Tools employing light and magnets can reveal what they do.
We know how many of the brain's pieces work. But how they add up to us?
Our brain is faster and more efficient than a PC. A new computer chip is almost as good.
Vision took 540 million years to evolve in nature. Computer scientists are inventing it in a decade.
