Figure 2 Mechanism of blood oxygenation level dependent functional magnetic resonance imaging.
BOLD-fMRI functions by detecting a local increase in relative blood oxygenation resulting from neurotransmitter activity and reflecting local neuronal firing rates. The nervous system activity is detected indirectly by assaying the proportion between deoxyhemoglobin and oxyhemoglobin in blood.
