Cognitive tasks may confound CBFV interpretation via systemic changes; leaves open whether controls for ABP/PetCO2 are needed in clinical research.
Do cognitive and motor activation paradigms induce systemic hemodynamic changes in healthy subjects?
Cognitive and motor activation tasks induce significant changes in systemic arterial blood pressure and PetCO2, which contribute to evoked changes in cerebral blood flow velocity alongside metabolic demand.
Moody et al. (2005) studied this question.
