Question

which procedures analyzes brain activity by monitoring blood flow to different areas of the brain?
a. a neural plate
b. functional magnetic resonance imaging
c. an electroencephalogram
d. amniocentesis

Explanation:

Functional magnetic resonance imaging (fMRI) measures brain activity by detecting changes associated with blood - flow. Neural plates are related to embryonic development, electroencephalograms measure electrical activity, and amniocentesis is a prenatal test.

Answer:

B. functional magnetic resonance imaging
