When one is sleepy and one attempt's to work on something cognitively demanding, such as doing algebra in one's head, or trying to imagine a house's interior in detail, what causes the "resistance" to focus on such problems?

I feel like part of the problem is related to circadian rhythm, particularly with respect to cortisol as a vigilance heightener. Surely there is more to this though.
