Summary
The relation between changes in CBF and CBV during hypercapnia was similar to that during neural activation; however, the relation during hypocapnia was different from that during Neural deactivation observed in crossed cerebellar diaschisis, suggesting that augmentation of CBFand CBV might be governed by a similar microcirculatory mechanism between neural activation andhypercapnia.
