The effect of aging on fMRI: Correction for the effects of vascular reactivity

Important paper from Tsvetanov, Cam-CAN et al. on vascular effects in aging in a sample of 335 subjects.

The scaling analysis revealed that much of the effects of age on task-based activation studies with fMRI do not survive correction for changes in vascular reactivity, and are likely to have been overestimated in previous fMRI studies of ageing.
