Pneumoencephalographic and skull X-rays are‚ how and why this was done‚ how long it takes to recover from this‚ and what the side effects are of having this done. Pneumoencephalography was a technique developed in 1919 for taking images of the brain‚ which floats in a sea of fluid. That fluid protects the brain from damage‚ but makes it very difficult to X-ray‚ since images taken through fluid are cloudy. Pneumoenceph alography involved drilling holes into the skulls of research subjects‚ draining
