Claim 13:
14. The method of claim 1, further comprising:
re-testing each control subject at least once after an interval at each arterial partial pressure of carbon dioxide to obtain a second set of vascular response signals representing at least one additional measurement of each control subject's control re-test vascular response per voxel;
computing a value representing a control difference between the respective vascular response and control re-test vascular response per voxel and per control subject;
wherein computing a set of statistical values of the vascular responses comprises computing statistical values for the control differences;
obtaining a re-test test subject vascular response signals representing the test subject's re-test vascular response; and
scoring a difference between the test subject's test vascular response and the test subject's re-test vascular response for respective voxels relative to the set of statistical values per corresponding voxel.
