This is super-interesting! What happens in non-arousal activity state shifts (eg reward)? How do populations relate to neurotransmitters produced in different cells? Can this explain why we see lower NVC in the hippocampus? (poss yes but doesn’t account for different capillary level responses).

How does blood flow relate to brain activity? We discovered that it reflects two neural populations affected oppositely by arousal. Together, they explain neurovascular coupling in all brain regions and brain states!
