Basically what we need to do is replace cells in those few areas of the brain that lose cells at a respectable rate, especially neurons, but we don't want to replace them any faster than that -- or not much faster anyway, because replacing them too fast would degrade cognitive function.
Practic ce trebuie sa facem este sa inlocuim celule in cele cateva zone ale creierului care le pierd intr-un ritm respectabil, in special in neuroni, dar fara sa le inlocuim mai rapid decat atat, sau nu cu mult mai rapid pentru ca daca le inlocuim prea rapid se degradeaza functiile cognitive.
