pet
eeg
the concentration of glucose in active regions of the brain underlies the * 2 points
usefulness of a(n)
eeg
mri
pet scan
hemispherectomy

Explanation:

1. EEG (electroencephalogram) measures electrical activity of the brain, which is related to brain - wave activity. MRI (magnetic resonance imaging) shows the structure of the brain. CT (computed tomography) is also mainly for brain structure. PET (positron - emission tomography) is more about metabolic processes.
2. PET scan measures metabolic activity in the brain, and glucose metabolism is an important aspect of it. EEG measures electrical activity, MRI shows structure, and hemispherectomy is a surgical procedure, not a scan for glucose concentration.

Answer:

1. D. EEG
2. C. PET scan
