"The implanted devices try to replicate the way brain cells communicate with one another. Let’s say, for example, that you are having a conversation with your boss. A healthy brain will convert that conversation from short-term memory to long-term memory by firing off a set of electrical signals. The signals fire in a specific code that is unique to each person and is a bit like a software command.

Brain diseases throw off these signaling codes. Berger’s software tries to assist the communication between brain cells by making an instantaneous prediction as to what the healthy code should be, and then firing off in that pattern. In separate studies funded by the Defense Advanced Research Projects Agency over the last several years, Berger’s chips were shown to improve recall functions in both rats and monkeys."
