It details their application in diagnosing Alzheimer's disease with the Pittsburgh compound B and their role in understanding drug addiction by examining dopamine receptor binding. Overall, PET technology is emphasized as a tool for gaining insights into brain-related conditions and emotional responses.

DAT prevents dopamine accumulation by clearing away unbound dopamine molecules from the synaptic cleft.
To determine the kinetic rate of a chemical reaction (c step) that follows an electron-transfer (e step), as illustrated by the oxidation of a neurotransmitter, dopamine.
