Really. Researchers are working on a computer chip that, implanted in your brain, could repair broken memory cicuits.
At the turn of the century (2000 that is) scientists at Duke University wired a monkey so its thoughts could control a robotic arm. More recently researchers at the University of Tübingen used brain waves to help paralyzed patients move a computer cursor. Now the folks at USC have developed a so-called "neural prosthesis" to mimic biological neurons.
The chip replaced a surgically removed section of a rat's brain and with 90% accuracy it converted incoming nerve signals into the correct output signals.
Maybe someday they'll have a chip that helps you selectively forget?
