The effect of ageing on fMRI : Correction for the confounding effects of vascular reactivity evaluated by joint fMRI and MEG in 335 adults
Abstract
In functional magnetic resonance imaging (fMRI) research one is typically interested in neural activity. However, the blood‐oxygenation level‐dependent (BOLD) signal is a composite of both neural and vascular activity. As factors such as age or medication may alter vascular function, it is essential to account for changes in neurovascular coupling when investigating neurocognitive functioning with fMRI. The resting‐state fluctuation amplitude...
