contrast dye injected into blood vessel allowing 3-D imaging

Question 9

MRI

Answer 9

Atoms spin in random directions but when exposed and some will flip and that will allow image

Question 10

fMRI

Answer 10

functional MRI
seeing activity of brain
detecting changes in blood flow and oxygenation

EEG when excited

Answer 15

shorter amplitude with more frequency

Question 16
