Harnessing The Power Of The Brain

Once in a while, we run across a science story that is hard to believe until you see it. That’s how we felt about this story when we first saw human beings operating computers, writing e-mails, and driving wheelchairs with nothing but their thoughts.

Quietly in a number of laboratories, an astounding technology is developing that directly connects the human brain to a computer. It’s like a sudden leap in human evolution - a leap that could one day help paralyzed people to walk again and amputees to move bionic limbs. As correspondent Scott Pelley reports, the connection has already been made for a few people, and for them it has been life changing.

Scott Mackler was a husband, father and successful neuroscientist when he received perhaps the worst news imaginable. At the age of 40, he could run a marathon in three and a half hours, but it was about that time he discovered he had ALS, Lou Gehrig’s disease.

His brain was losing its connection to virtually every muscle in his body. The near-total paralysis would also stop his lungs. He didn’t want to live on a ventilator, so nine years ago he recorded this message for his two sons.

“I know the future holds lot of love and joy and pride and that life goes on and I’ll be watching you along the way and I love you very much and I’ll see ya,” he said in a home video.

Today, Scott Mackler’s mind is sharp as ever, but his body has failed. Doctors call it “locked in” syndrome. Scott and his wife Lynn learned to communicate with about the only thing he has left, eye movement.
