MRI (Magnetic Resonance Imaging) uses powerful magnetic fields and radio waves to produce detailed images of the body, including the brain. It can differentiate between different types of tissue, making it an excellent tool for studying brain structure and function. CT (Computed Tomography) uses X-rays and is better suited for detecting structural problems or injuries but does not provide the same level of detail as an MRI for brain function. PET (Positron Emission Tomography) and EEG (Electroencephalography) can also be used to study brain function, but they are not imaging techniques and instead measure brain activity through other means. RAS (Reticular Activating System) is not a scanning device but rather a part of the brainstem that regulates arousal and wakefulness.
