Abstract :
The response of cerebral blood flow to increases and decreases in blood pressure have been reported to differ. The potential impact of this on the commonly used linear-time-invariant modelling of only spontaneous changes in blood pressure has so far not been tested. Results show that this could have a major impact on quantitative measures of cerebral autoregulaton.
