There are numerous methods in place to research the brain. One of the most common ways to conduct research is to conduct Clinical Studies. In CS, research can alter the brain of the subject (usually animals like rats and mice) and observe what each area affected changes. This manipulation of the brain can help pinpoint what each area does. Another method to research the brain is to record its eletrical activity. This is done with an electroencephalogram or EEG. This device graphs brain waves are researchers can analyze the waves according to different stimuli. Other types of scans are CT and PET scans. Both create images of the brain and its activity levels. PET scans show activity by analyzing where the brain consumes glucose. The last type of scans, and MRI, scans the head with a magnetic field to affect the brain's atoms which upon returning to normal state release signals, which are then analyzed by a computer. MRI scans can help to see areas where there is soft tissue and an abundance of fluid. (Charline)
