Brain imaging helps us understand and treat various brain disorders: Alzheimer's disease: PET scans detect amyloid plaques and monitor disease progression. Depression: fMRI studies brain activity changes, aiding in identifying specific brain regions involved.
Methods used to study the brain's structure include computed axial tomography (CAT) scans and magnetic resonance imaging (MRI). CAT scans show the size, shape, and position of internal structures by using computer technology to combine a series of X-rays into a detailed image of the skull and brain.
The correct answer is A and I'm not sure why. How would I be able to discern between the two on the test? I know that PET scans are used to measure glucose uptake in the brain which allows you to measure brain activity, but MRI measure brain activity by measuring blood flow.
Psychologists study the brain with many different methods. Neuroimaging, or brain scanning, includes the use of various techniques to directly or indirectly image the structure, function, or pharmacology of the brain. It is a relatively new discipline within medicine, neuroscience, and psychology.
Methods covered include functional and structural magnetic resonance imaging, positron emission tomography, electroencephalography, magnetoencephalography, multimodal imaging, and various brain stimulation methods.
Good For: Studying the relative metabolic activity of various body regions; full body scans are used to find cancer metastases (more cell division = higher average metabolism), brain scans are used to measure relative activity of different brain regions to look at things like normal brain vs Alzheimer's vs cancer vs etc.
