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.
Ne themel, ajo cka duhet te bejme eshte ti zevendesojme qelizat ne ato pjese te trurit ku humbasin qelizat me shkalle te larte, sidomos neuronet, por nuk duam ti zevendesojm ato me shpejt se aq -- ose jo shume shpejt gjithesesi, sepse duke i zevendesuar ato shum shpejte do te degradonte funksionet njohese.
