Assessing TD fNIRS capability to detect hemodynamic oscillations in cerebral cortex

We present a simulation study to evaluate the feasibility of using Time Domain fNIRS to monitor hemodynamic oscillations in biological tissues like the cerebral cortex. Two geometries (slab and two-layer medium) were considered to define the optimal acquisition parameters and to assess the ability of the technique to detect and separate oscillations occurring at different depths within the probed medium by exploiting the time-gating of TD fNIRS signals.
