Figure 9. Calculated flow rate for brain arteries from rat and gerbil and cochlea arteries from gerbil.

Male rat mid-cerebral artery (A) taken from Geary et al 1998 [19], male gerbil basilar artery (B) male gerbil anterior inferior cerebellar artery (C), female rat mid-cerebral artery territory branch (D), male gerbil spiral modiolar artery (E), male gerbil radiating arteriole (F). Green bars represent estimated physiological pressure range for each vessel according to which active and passive slope were calculated. Slope is given in µl/min –cmH₂O. For active slope diameter was obtained in 10 µM L-NNA, for passive slope diameter was obtained in Ca²⁺-free solution.
