vote to close: aside from being self-help, this question cannot be answered adequately. 'required' amount of sleep will vary with the individual, and is certainly not a step function. also, what are 'peak levels' of brain functionality? if we broaden the criteria required for an answer, then the question is simply asking for a review of sleep studies on cognition.

I closed this question as I think it indeed is too broad, you could narrow it down and already look up some initial resources. You mention 'the internet points to some very basic conclusions', which ones? Perhaps verify first whether those are correct and ask about that? I [started a discussion in chat](http://chat.stackexchange.com/transcript/message/10902121#10902121) since it got so many up votes, so others might overrule me. For a more focused example of a sleep-related question you could check out: http://cogsci.stackexchange.com/q/868/21

P.s. some of the papers I link to in that question might get you started reading up on the subject.

@user1477388 Feel free to edit the question to improve it, simultaneously bumping it. This way it might receive reopen votes. As it is the question did not change, so I see no reason to reopen.
