A New Approach to Estimating the Evoked Hemodynamic Response Applied to Dual Channel Functional Near Infrared Spectroscopy

Abstract Background Brain activity can be measured non-invasively by means of functional near-infrared spectroscopy (fNIRS) which records hemodynamics of the brain tissue. Sensitivity of fNIRS to the brain activity is however being affected by natural physiological brain hemodynamics (systemic inter...
