Identification of negative BOLD responses using windkessel models

2018-08-16

Abstract excerpt

Alongside positive BOLD responses (PBR), a variety of negative BOLD responses (NBR) with distinct underlying mechanisms also occur. We identify five mechanisms of NBR: i ) local/lateral/contralateral inhibition (LCI), ii ) neuronal disruption of network activity (NDA), iii ) altered balance of neuro-metabolic/vascular couplings (ANC), iv ) arterial blood stealing (ABS), and v ) venous blood backpressure (VBB)...
