Function of Brain Mapping

The Function Of Brain Mapping


Brain mapping means using scanning technologies to actually look inside the brain. This is also known as neuroimaging and it includes techniques such as magnetic resonance imaging (MRI), CT scan and MagnetoEncephaloGraphy (MEG). These use radiation and magnetic fields which, projected onto a computer screen, show what's going on inside the brain.

Research Into Brain Functions

Function of Brain MappingThe main function of brain mapping is to research the different parts of the brain and how they function together. Over a hundred years ago, x-rays gave researchers the first glimpses of the inner working of the brain. Everything we know about the brain today comes from neuroimaging and the clear, detailed pictures it allows us to see by computer. This technology continues to evolve and teach us more about how this amazing organ functions.

Diagnosing Brain Diseases

Another important function of brain mapping is to detect diseases. It's an important diagnostic tool for doctors. Neuroimaging is most useful for detecting brain cancer. It can see if there's an abnormal growth and also chart the progress of this growth. Scanning technologies are the main diagnostic tool in determining whether a person suffers from brain cancer or other ailments.

Help With Brain Trauma

Brain mapping is also extremely useful in dealing with trauma to the brain. Brain injuries are especially tricky to deal with because it's so hard to tell exactly what part of the brain has been damaged. It's hard to match symptoms with certain areas of the brain because most areas handle so many different functions. For example, disturbances in language ability could indicate that one of several different parts of the brain has suffered damage. One function of brain mapping is to show exactly where trauma has occurred and this is key in choosing the right rehabilitation plan.

How Brain Mapping Works In More Detail

Although they use different means of scanning the brain, all neuroimaging works in a similar way. Your body is placed inside a scanner that usually looks like a large donut. Once inside, it measures brain activity; this could be either electrical impulses or the gamma ray emissions of radioactive materials given to you. The image is projected on a computer screen for researchers to see. These days, images are extremely sharp and detailed. Images can be saved or printed so that the patient can see them as well.

The main function of brain mapping is to research the parts of the brain and how they work together. But another function of brain mapping, and one that's more important in many ways, is in diagnosing, monitoring and treating diseases and injuries. As this technology evolves, doctors are better able to use it to treat these ailments effectively.
