Darek Fidyka was stabbed in the back four years ago, paralyzing him from the chest down.
Now we hear of a stunning success after experimental treatments that Fidyka has regained some feeling in his lower body and is learning to walk again. According to the Popular Science article, the treatment involved removing part of Fidyka's brain and then injecting those cells into the damaged area of his spinal cord.
The tissue removed were olfactory bulbs (this is the part of the brain that allow you to smell) growing cells from the bulb and eventually injecting them. Curiously the reason this brain tissue was used is because the nerves in the olfactory system are the only part of the human nervous system known to regrow after being damaged. (Fidyka reported no ill effects from the removal)
