Abstract

We investigated the depth of systemic oscillations, as the heartbeat, always present in the optical signal. To this aim we performed measurements in the head of humans and piglets using frequency domain and time domain systems. Measurements in piglets and Monte Carlo simulations have also been used towards explaining the experimental data. Preliminary results indicate that with time and frequency domain we are able to isolate the heartbeat contribution originated from intracranial layers (brain).
