WebMar 3, 2024 · Traditional fMRI imaging measures changes to blood flow in the brain, as a proxy for neural activity. When neurons receive signals from other neurons, it triggers an influx of calcium, which causes a diffusible gas called nitric oxide to be released. Nitric oxide acts in part as a vasodilator that increases blood flow to the area. WebSep 1, 2006 · So according to critics, what fMRI really measures is a correlation between blood flow and activity, and not the brain activity itself.
