Fascinating result despite the questionable ethics of inducing a second stroke.
Scientists reopened the window in mice by inducing a second stroke, helping the rodents rehabilitate to their pre-stroke abilities, however this is not an option for humans.
Mice were taught to grab a food pellet through a slit in their cage -- an unnatural skill for four-legged animals -- before scientists induced a strokes. Those that had a second stroke in the same region of their brain recovered the skill faster than mice what had a stroke in a different region.
The mice become proficient after 10 days of training.
