"Synaptic transmission mediated by G-protein coupled receptors (GPCR) is not generally thought to be point-to-point. To determine the extent over which dopamine signals in the midbrain, the present study examined the concentration and time course of dopamine that underlies a D-2-receptor IPSC (D-2-IPSC) in the ventral tegmental area," investigators in the United States report (see also Neuroscience).
"Extracellular dopamine was measured electrochemically while simultaneously recording D-2-IPSCs. The presence of dopamine was brief relative to the IPSC, suggesting that G-protein dependent potassium channel activation determined the IPSC time course. The activation ...
