Document Summary

Majority of questions are from lecture notes, several from the textbook. Neuroimaging and brain structure: neuroimaging: pictures of the brain. Allows for a window on brain structure and function: imaging brain structure. Computerized axial tomography (cat or ct scan) Nothing to do with x-rays (magnetic field) Operates via strong magnetic field around head. X-rays are ionized, destroys tissues: utility: locating tumors, injuries, structural or anatomical abnormalities, neuropsychological location: neuroimaging structure and functioning (halstead reitan test) important. Neuroimaging and brain structure cont"d: imaging brain function. Positron emission tomography (pet) injection of radioactive isotopes. They react with oxygen, blood, and glucose in the brain. Functional mri (fmri) vs. mri a view of brief changes in brain activity (ask to do something to trigger different parts of the brain) Ptsds (post traumatic stress disorder)(numbing) have different brain activity than those (hyperarousal) reactive: advantages and limitations. More generally assess brain structure, function, and activity of the nervous system (much more emotional: psychophysiological assessment domains.
