Spiperone
Spiperone is a psychoactive drug and research chemical belonging to the butyrophenone chemical class. It functions as a 5-HT1A, 5-HT2A, 5-HT7, and D2 receptor antagonist, and has been used to identify these receptors when labeled with tritium. It has negligible affinity for the 5-HT2C receptor...

Dopamine
Dopamine is a catecholamine neurotransmitter present in a wide variety of animals, including both vertebrates and invertebrates. In the brain, this substituted phenethylamine functions as a neurotransmitter, activating the five known types of dopamine receptors—D1, D2, D3, D4, and D5—and their...

Positron emission tomography
Positron emission tomography is nuclear medicine imaging technique that produces a three-dimensional image or picture of functional processes in the body. The system detects pairs of gamma rays emitted indirectly by a positron-emitting radionuclide , which is introduced into the body on a...
