A previous question dealt with whether it is possible to catch up on lost sleep. This question is a little different.

Assume that a healthy adult has been deprived of sleep for "x" hours. How much sleep is required to restore healthy brain function, compared to sleep lost?

I wouldn't think the hours needed could be predicted by a linear scale.
Is there some predictable relationship between the two and what type of relationship is it?

Many times I feel it's not just about sleeping more hours and it will recover the hours u didn't slept before, I feel its more like, just go back to normal routine, and how many days you will need to get used to it again, imo, sleeping too much each time won't recover anything –  Enoque Duarte Aug 12 '13 at 10:10
I can give it some search, I dont know if it is exactly right that, or there is also some exact calcs. I tought that way because, evry1 has his body, every1 has different activitys with diferent effort and exhaustion levels, diferent evrything!, also, you can notice that when you sleep many hours at once you feel damn tired, still there might be some calcs and studs about that for sure, I'll give it a search when I have some free time since I'm intrested on it too :d –  Enoque Duarte Aug 12 '13 at 12:13
