Quizplus · Accepted Answer

Brain scans, such as functional MRI (fMRI) or PET scans, show the activity and location of various brain regions during different tasks or experiences. However, they do not reveal the underlying mechanisms or reasons for why certain brain regions are active or inactive. To understand the how and why of brain functioning, researchers often combine brain imaging with other techniques such as behavioral experiments, genetics, and cellular studies.
