WebFunctional Magnetic Resonance Imaging (fMRI) is the most widely used technique for investigating the living, functioning human brain as people perform tasks and experience mental states. It is a convergence point for multidisciplinary work from many disciplines. WebWhat FMRI Measures. Oxygen is delivered to neurons by haemoglobin in capillary red blood cells. When neuronal activity increases there is an increased demand for oxygen and the local response is an increase in blood flow to regions of increased neural activity. Haemoglobin is diamagnetic when oxygenated but paramagnetic when deoxygenated. how is methane gas produced in landfills https://krellobottle.com
