A scientist is testing the hypothesis that inhibiting neural activity in the prefrontal cortex could help relieve depression. Which technique would be most useful for testing this hypothesis?

Question

Quizplus · Accepted Answer

TMS is a technique where magnetic pulses are used to inhibit or stimulate neural activity in the brain. It can be targeted to specific brain regions such as the prefrontal cortex to test the hypothesis that inhibiting neural activity in this area could relieve depression. CT and MRI are imaging techniques that can help visualize the brain, but they do not directly manipulate neural activity. PET is a technique that measures brain activity by detecting radioactive tracers, but it does not directly inhibit or stimulate neural activity.
