Figure 38-7 This Lifescan printout was obtained approximately 3 minutes after occlusion (XC) of the left carotid artery. It shows attenuation of activity on the left with occlusion. The electroencephalogram showed a similar change. The regional cerebral blood flow with occlusion was 9 mL/100 g/min.
