as neuronal cells are famous for being powered anaerobically using glucose and/or ketones

Neurons are not famous for being powered anaerobically; if anything, they're famous for being powered exclusivelly-aerobic.

AFAIK, the neurons are dependent on oxygen, thus aerobic. And unless I'm wrong, the ketones for energy is also an aerobic process. The place where we normally find anaerobic metabolism is in muscles, which are able to produce ATP using glucose to lactic acid without oxygen.
