A PET scan (Positron Emission Tomography) is the most likely technology to be useful to the researchers in this situation. PET scanning uses a radioactive tracer to show the metabolic activity of tissues, including the brain. This would allow the researchers to visualize which specific parts of the rat's brain are most active as it listens to music. CAT scans, MRI, and X-rays are not typically used to measure brain activity in this way.
