Question

The neurosurgeons detected the insufficient blood flow to Mrs. F.'s brain by observing her EEG record, which showed slow wave activity. Slow waves are indicative of general decreased activity in the brain, specifically in the cortical neurons. This suggests that the part of her brain that is controlled by the left common carotid artery is not receiving enough oxygen and nutrients to maintain normal activity.
