Rat Exerciser

After graduate school, Marc Kubasak set an ambitious goal: Find a way for
paralyzed people to walk. But to help people, first he had to help rats.
Kubasak took paralyzed animals, transplanted glial cells from the olfactory
bulb in the brain to the injured area, and then retrained them to walk. That
involved sewing little vests to suspend the rodents from a robotic arm. Then,

on a treadmill for five to 12 hours a day, five days a week.” He walked 40

damaged in a knife attack.
