Question

dr. charles is using ____ when she conducts a series of brain scans by using radio waves to briefly disrupt the brains activity.

• single - cell recording
• an electroencephalogram (eeg)
• positron emission tomography (pet)
• functional magnetic resonance imaging (fmri)

Explanation:

Functional magnetic resonance imaging (fMRI) uses radio - waves and a strong magnetic field to detect changes in blood flow in the brain, which can be used to briefly disrupt and study brain activity. Single - cell recording measures the electrical activity of a single neuron. An electroencephalogram (EEG) records the electrical activity of the brain from the scalp. Positron emission tomography (PET) uses radioactive tracers to visualize and measure changes in metabolic processes in the brain.

Answer:

D. functional magnetic resonance imaging (fMRI)
