Cerebrovascular reactivity has negligible contribution to haemodynamic lag after stroke: implications for fMRI studies
BACKGROUND: Functional MRI is ubiquitously used to study post-stroke recovery. However, the fMRI-derived haemodynamic responses are vulnerable to vascular insult which can result in reduced magnitude and temporal delays (lag) in the haemodynamic response function (HRF). The aetiology of HRF lag rema...
