Multi-echo investigations of positive and negative CBF and concomitant BOLD changes

Multi-echo investigations of positive and negative CBF and concomitant BOLD changes

Unlike the positive blood oxygenation level-dependent (BOLD) response (PBR), commonly taken as an indication of an ‘activated’ brain region, the physiological origin of negative BOLD signal changes (i.e. a negative BOLD response, NBR), also referred to as ‘deactivation’ is still being debated.
