Illustration of the CA bench-model (a) and the experimental setup (b). The pump was controlled using LabVIEW (National Instruments Corporation, Austin, Texas, US), to recreate aqueductal pulsatile flows based on CA flows measured in 43 healthy elderly and 22 idiopathic normal pressure hydrocephalus (INPH) patients [11]. Q is the pulsatile flow rate, DP is Differential pressure. Reference value for intracranial pressure in healthy in the supine position [31]
