Hemodynamic changes during the body-tilting task for all participants.

<p>Left two columns: hemodynamics estimated by the conventional method. Middle two columns: systemic component by the proposed method. Right two columns: functional component by the proposed method. Data were block averaged. Distance between source and detector was 30 mm. Red and blue lines indicate oxy- and deoxyhemoglobin changes, respectively. Red and blue bands indicate SDs for oxy- and deoxyhemoglobin changes, respectively. Green line indicates the task period. “Left” and “Right” indicate the measurement positions.
