"Dr. Leonard Shlain, chairman of laparoscopic surgery at California Pacific Medical Center, said they took some four and five year-olds and gave them video games and asked them to figure out how to play them without instructions. Then they watched their brain activity with real-time monitors. At first, when they were figuring out the games, he said, the whole brain lit up. But by the time they knew how to play the games, the brain went dark, except for one little point."
