The Brain and ketones

Interesting fact I picked up listening to HVMN Episode 29 with Dominic D'Agostino as guest: The same neurological pathways involved with lactate are involved for ketones in the brain. Hypoxia induces these. Which brings me to think about strategies for activating ketone pathways in the brain for improving brain ketone utilization. Can mild hypoxia have a hormetic effect? I would like to find good sources for this. https://en.wikipedia.org/wiki/Beta-Hydroxybutyric_acid
