“…[ 18 F]FDG accumulates intensely in the myocardium and brain, as both are high glycolytic metabolic sites (Shreve et al, 1999). The brain glucose metabolism reflects in part the energy required for neurotransmission, so regional abnormalities in this process provide mechanistic information on specific neurotransmitters associated with these changes (Fowler et al, 1967). After the intake of a psychostimulant drug, such as cocaine, temporally limited function changes occur in the brain (Peña et al, 2015; Ungless et al, 2001; Xu et al, 2017).…”
