Brief Summary
The purpose of this study is to explore how arterial PaCO2 effect regional Blood Oxygen Level Dependent (BOLD) signal, and indirectly the brain regional O2 level .
Detailed Description
Among many parameters effecting cerebral blood flow(CBF), partial pressure of CO2 (PaCO2) in arterial blood has a significant effect. A small increase in arterial PaCO2 level will cause a significant ...
