Among the advanced technologies used to study the brain's structure and functions, which one provides detailed three-dimensional images of the brain's structures and activities?
a. functional magnetic resonance imaging
b. transcranial magnetic stimulation
c. electroencephalogram
d. positron emission tomography

Among the advanced technologies used to study the brain's structure and functions, the one that provides detailed three-dimensional images of the brain's structures and activities is known as A. functional magnetic resonance imaging, or fMRI.
It measures brain activity based on blood flow in a certain region of the brain, given that when a brain part is in use, blood flow is increased in that part.
