CT Scanning

The computed tomography scan is the simplest way to produce an image of the brain. A CT scanner emits X-rays which pass through the skull and are collected on the opposite side. We can then create an image based on how the X-rays are absorbed, just like how we look for broken bones. The softer the part of the body, the less X-rays it absorbs. This is great for studying the structure of the brain on a large scale but tells us nothing about activation in the brain which limits its application when studying the brain for psychological reasons. However, it can be very useful in the medical field when searching for abnormalities in the brain.
