Physiological origin for the BOLD poststimulus undershoot in human brain: vascular compliance versus oxygen metabolism
The poststimulus blood oxygenation level-dependent (BOLD) undershoot has been attributed to two main plausible origins: delayed vascular compliance based on delayed cerebral blood volume (CBV) recovery and a sustained increased oxygen metabolism after stimulus cessation. To investigate these contrib...
