Is There a Depletion in the Brain?

The glucose model of this kind of self control strength that we have has been pretty affirmatively denied. And because some of those components are blood vessels and nerves and neurons, wouldn't it make perfect sense that there's depletion in the brain, just like there is in a bicet? So i am going to propose something bold and perhaps stupid. What can i guess? Part one and part two? I would ask our listeners let us know if you hate this idea. It's obviously just coming up at the spur of the moment.
