Question 11

Neuroimaging

Answer 11

Technique that allows to obtain images of the awake human brain

Question 12

Computing tomographic (CT)

Answer 12

Two-dimensional x-ray images; diagnose and plan surgery/treatment

Question 13

Magnetic Resoning

Answer 13

Magnetic fields produce 3d images; safer than CT but CT is faster

Question 14

Diffusion tensor imaging

Answer 14

measures white matter

Question 15

Transcranial magnetic stimulation

Answer 15

delivers magnetic pulse to certain areas to view activity

Question 16

Position emission tomography

Answer 16

see activity during a task, radioactive glucose is added to the brain and will move to the part of the brain that is active. the radioactivity is measured by the machine and allows to see specific neurochemicals

Question 17

Functional MRI

Answer 17

Combines MRI with activity scaning. Measures the use of oxygen and can map the brain.
