Document Summary
To gain an experimental control, scientists often create brain damage in animals. This process is known as lesioning a technique in which researchers intentionally damage an area in the brain. Researchers can study human brain functions using transcranial magnetic stimulation (tms), a procedure in which an electromagnetic pulse is delivered to a targeted region of the brain. It is a temporary lesion that is used to investigate a number of cognitive processes. Structural neuroimaging is a type of brain scanning that produces images of the different structures of the brain. This is used to observe the size of different brain areas to determine where the damage is. There are 3 commonly used types of structural neuroimaging. Computerized tomography (ct scan) is a structural neuroimaging technique in which x-rays are sent through the brain by a tube that rotates around the head.
