The primary tools of the trade are positron-emission tomography (PET) and single-photon-emission computed tomography (SPECT) scans, with which scientists can find and measure changes in dopamine and other neurochemicals in the brain.
Some of these have been combined with rapidly advancing biophysical technologies like computer-assisted EEG analysis or quantified-EEG (QEEG), magnetic resonance imaging (MRI) and functional magnetic resonance imaging (fMRI), positron emission tomography (PET), and single-photon-emission computed tomography (SPECT).
