In August 2014, IBM announced that it had built a “brain-inspired” computer chip—essentially a computer that was wired like an organic brain, rather than a traditional computer. These chips are designed to work like neurons—the brain’s nerve cells. Wired reported on Aug. 17 that the team working on the brain chips recently hit a new milestone—a system has about 48 million digital neurons, which is roughly as many as found in the brain of a rodent.
