It’s the stuff of science fiction…scientists take a computer plug and insert it into an opening in a patient’s head, enabling the subject to broadcast her thoughts through a computer. Now scientists at Duke and Brown University, as well as other centers, are starting to figure out how to connect computers to our minds. In one experiment, electrodes were inserted deep into the brain of a monkey, allowing the subject to control a robot arm with thoughts alone. In another lab, a paralyzed patient was able to move a cursor on a computer screen. People suffering from paralysis may be able to control their environment through thought within 5 years, the optimists say. And in the distant future, might we interface our minds directly with the Internet? Where would you think yourself?
