If you heard a single violin playing Beethoven's 5th, you would be able to tell what piece of music was being played even though the rest of the orchestra was not heard. In the same way, by monitoring a relatively few neurons, computers can recognize patterns and allow programming based on these patterns to say, know if a mouse is thinking about pushing his water lever. You can pass the time waiting for Matrix-style video games and motionless system adminstration/utilization by reading the full article."
