Cerebral blood flow and its autoregulation - when will there be some light in the black box?

When considering autoregulation, it is interesting to first consider the cerebral perfusion of a giraffe. Although their necks are about 2.5 m long, they must be able to drink water from the ground level of the oasis and then eat leaves from trees, causing large changes in cerebral perfusion pressure. Fortunately nature has provided them with several cardiovascular, anatomical and physiological adaptions to enable them to do so without fainting.¹
