I am not a biologist - my background is in quantitative sciences, and I am trying to answer a rather quantitative question:
How much oxygen does a brain consume?
This however raises many sub-questions of purely biological nature:
- How is the brain supplied by oxygen? (My naive understanding is that lungs tie oxygen to hamoglobin, which is then carried by blood to cells, which then ingest the oxygen, converting it to ATF. Is this correct? Does this apply to neurons as well?)
- How much energy a neuron or the whole brain consumes per unit time? (e.g., per hour, in energy units or oxygen content)
I will appreciate explanations in laymen terms or references to accessible literature.
