Neural Mechanisms of Age-Related Slowing: The ΔCBF/ΔCMRO(2) Ratio Mediates Age-Differences in BOLD Signal and Human Performance
The precise mechanisms that give rise to the blood-oxygen-level-dependent (BOLD) activation differences that accompany age-related cognitive slowing remain fundamentally unknown. We sought to isolate the origin of age-related BOLD changes by comparing blood-flow and oxygen-metabolic constituents of...
