Positron emission tomography (PET) is the most useful technique for locating specific neurotransmitter activity in the brain. PET involves injecting a radioactively labeled tracer substance into the bloodstream, which is then taken up by the brain and metabolized in a manner specific to the neurotransmitter being studied. The tracer emits positrons, which collide with electrons in brain tissue and produce gamma rays that can be detected by the scanning equipment, creating a map of neurotransmitter activity in different areas of the brain.
