Document Summary
5. 1 methods of visualizing and stimulating the living human brain. E-ray photography is effective in characterizing internal structures that differ substantially form their surroundings. Involves injecting one compartment of the body with a substance that absorbs x-rays less than or more than the surrounding tissue. Cerebral angiography uses the infusion of a radio opaque dye into a cerebral artery to visualize the cerebral circulatory system during x-ray photography. Computed tomography (ct) computer assisted x-ray procedure that can be used to visualize the brain and other internal structures of the living body. X- ray tube and detector are moved along the axis of the patient"s body to another level of the brain. Procedure in which high-resolution images are constructed from the measurement of waves that hydrogen atoms emit. Provides high spatial resolution (ability to detect and represent differences in spatial location) First brain imaging technique to provide images of brain activity rather than images of brain structure.
