Document Summary
Study brain activity through the change in blood flow. Provides both an anatomical and a functional view of the brain. Reveal bundles of myelinated axons in the brain. Measure water molecule because these molecule move parallel to the axon. Stimulation (tms) region and find out what behaviour is affected. Images produced are very high resolution (as detailed as 1 millimeter) Study brain activity through radioactivity (thus show the function of the brain) Provides detailed view of the brain in different dimensions. No x-rays or radioactive material is used. Better than mri to evaluate skull fractures. Provide detailed images of the brain nervous tissue. It can only capture a clear image if the person being scanned stays completely still. Can only look at blood flow in the brain and not the activities of neurons. Cannot be used in patients with metallic devices, like pacemakers. Cannot be used with patients who are claustrophobic (afraid of small places)
