Websuch as fMRI, SPECT, and EEG that provide the functional information of the brain. However, these techniques have some limitations including immobility, cost, and motion artifacts. One of the most emerging portable brain scanner available today is functional … WebBasis for fMRI. fMRI is of course based on MRI, which in turn uses Nuclear Magnetic Resonance coupled with gradients in magnetic field 38 to create images that can incorporate many different types of contrast such as T1 weighting, T2 weighting, susceptibility, flow, etc. 7 In order to understand the particular contrast mechanism predominantly used in fMRI it …

Introduction Functional near-infrared spectroscopy (fNIRS) is a non-invasive neuroimaging technique that uses light in the near-infrared range to measure hemodynamic response changes associated with neuronal activity in the brain [ 1, 2 ].
