Always fascinating to me how we are brains, trying to understand how we work. Cool research!
A physicist is just atoms studying other atoms.
So you can get brain hard?

Brain blood perfusion is quite amazing.

I don't understand from their research if

1) The the blood flow is following the computational/metabolic demand (via the endothelial cells communicating via gap junctions)

2) the brain is signaling the endothelial cells directly.

Maybe the paper explains it, or maybe more research required.

Recently I started taking an angiotensin II receptor blocker as a medication to lower my blood pressure. The first week was difficult because my body couldn't significantly raise blood pressure during periods of sustained effort, like exercise and yardwork. I believe I'm over this now. Fortunately, the medication seems to be effective and I haven't experienced any negative side effects yet. Some people who take this medication have reported bad side effects, including "brain fog" while using it. I wonder if/how this medication might interact with the blood pressure control mechanisms observed in this research.
I also take an angiotensin II receptor blocker and my experience has been similar. Additionally, I experience a perceived effect on stress levels as my pulse and blood pressure do not rise in stressful situations.

On the negative side, I definitely have a harder time reaching my maximum pulse when working out.
