A density plot presenting the tabulated data shown in Table 1 binned at a finer resolution, using color intensity to represent relative frequency within the data set of 1,998,944 6-second time windows. The plot shows bimodal behavior of ICP pulse amplitude with respect to mean ICP for mean ICP > 12 mm Hg, demonstrating that in practice there is not a functional (one-toone) relationship between static and pulsatile ICPs.
