Abstract: The aim of our study was to explore the possibility of detecting
hemodynamic changes in the brain using the phase of the intensity
modulated optical signal. To obtain optical signals with the highest possible
signal-to-noise ratio, we performed a series of simultaneous NIRS-fMRI
measurements, with subsequent correlation of the time courses of both
measurements. The cognitive paradigm used arithmetic calculations, with
optical signals acquired with sensors placed on the forehead. Measurements
