Exploring the post‐stimulus undershoot with spin‐echo fMRI: Implications for models of neurovascular response
As a consequence of neural stimulation the blood oxygenation‐level dependent (BOLD) contrast in gradient‐echo echo‐planar imaging (GE‐EPI) based functional MRI (fMRI) leads to an increased MR signal in activated brain regions. Following this, a BOLD signal undershoot below baseline is generally obse...
