Authors present new aspects of recently published non-invasive method of near-infrared transillumination/back scattering (NIR-T/BS) in its application for recording of changes in instantaneous width of the subarachnoid space (SAS) , as source of information on the amplitude of cerebrovascular pulsation in subsequent phases of the cardiac cycle. For confirmation of the crebidility of the recording as carrying information on the changes within the SAS, recordings were also performed after non- invasive elimination of skin circulation in the sensor area with skin compression. It was proved that the pulsation recorded with this technique is really of intracranial origin, regardless of the blood flow in the skin of the frontal region.
