Answer:
Neuroimaging, or brain scanning, includes the use of various techniques ( Four of the most common types of brain scans are EEG, PET, MRI, and fMRI )to directly or indirectly image the structure, function, or pharmacology of the brain
Explanation:
Electroencephalography (EEG) is used to show brain activity under certain psychological states, such as alertness or drowsiness.
Positron emission tomography (PET) scans show brain processes by using the sugar glucose in the brain to illustrate where neurons are firing.
Magnetic resonance imaging (MRI) scans use echo waves to discriminate among grey matter, white matter, and cerebrospinal fluid.
Functional magnetic resonance imaging (fMRI) scans are a series of MRIs measuring brain function via a computer’s combination of multiple images taken less than a second apart. With this different scan it is possible for the function and structure of the brain to be determined.
