A)PET scan
B)MRI scan
C)ERP recording
D)TMS

Question

Quizplus · Accepted Answer

PET scan (Positron Emission Tomography) uses radioactive tracers to measure blood flow and metabolic activity of neural tissue. It is based on the principle that active neurons require more glucose and oxygen, which increases blood flow to those areas. As the tracers decay, they emit positrons that collide with electrons, resulting in gamma rays that can be detected by the PET scanner. This allows for the visualization of brain function and activity. The other options (B) MRI, (C) ERP recording, and (D) TMS do not directly measure blood flow and metabolic activity in the brain.
