Seizures

Adding to the absurdity of the London 2012 brand, The Times reports that the logo may cause epileptic seizures. My complaint is that it is miserable. This brain lateral cross section taken from neurology.edu. In approximation, the more dense a material is, the whiter a volume of it will appear on the scan (just as in the more familiar "flat" X-rays). CT scans are primarily used for evaluating swelling from tissue damage in the brain and in assessment of ventricle size. Modern CT scanning can provide reasonably good images in a matter of minutes, like this one.
