2.Method: 1. Record the normal wave of evoked potential before exsanguinated. Hemorrhage maked the blood pressure descend each 10mmHg (1.33 kPa), and recorded evoked potential at each blood pressure point. Measured CEP latent period, positive wave values, negative wave values, p-p values and its timing and F-VEP P_2-N_2 values, P_2 latent period, until systolic pressure was 40 mmHg(5.32 kPa).
