Example of the Artifact removed (AR)-ICP signal segmentation of one subject. A After low-pass filtering the AR-ICP signal, with respiratory and pulse contributions to the signal removed to generate the AR-low-pass (ARLP)-ICP signal; B After extracted extrema from ARLP-ICP signal; C After segmentation using desired minima; and D After z-normalization of the segmented AR (ZNAR)-ICP signal
