Professor Kingston is interested in understanding the origins of gambling addictions. To study the brain activity of gambling addicts, Professor Kingston tracks oxygen flow in their brains while they engage in online gambling. What method is he most likely using? a. single cell recording b. transcranial magnetic stimulation c. functional magnetic resonance imaging d. magnetoencephalography

B) Functional magnetic resonance imaging

Explanation:

fMRI or Functional magnetic resonance imaging is the technique which is used to measure the neural activity in the brain of humans and other animals.

The technique is based on the concept that the activity in the neurons is coupled to the flow of the blood in the neurons. The change in the rate of blood flow to the region of neurons shows that that part of the neuron is activated at that time.

Therefore by measuring the changes in the blood flow, the technique scans the neural activities of the brain.

Thus, Optio-B is the correct answer.
