Påstand hentet fra en [vox-artikkel](https://www.vox.com/future-perfect/24032884/psychedelics-gul-dolen-critical-period-blindness-stroke). Veldig spennende forskning. > [[The critical period]] for motor learning, just like other critical periods, closes as you get older. But it reopens for about two months right after you have a stroke, as the brain is trying to adapt to its new situation. Then it closes again. So if you don’t get the right kind of physical therapy within two months after having a stroke, the extra physical therapy isn’t really going to give you much more improvement after that. > > I said, look, even for those people whose critical period closed a year ago, I think we can use these drugs to reopen them and then give them physical therapy as the paired adjunct to the psychedelic, and then we’ll be able to restore this ability to learn.
