Welcome to the NEW Baltimore County volunteer site! We encourage agencies in Baltimore County and the surrounding communities to create a profile to highlight their volunteer needs. We invite people searching for volunteer opportunities to use either the quick search tool above or register as a volunteer from the drop-down menu at the top of the page.
By inhibiting the dopamine transporter, a dopamine reuptake inhibitor increases the body's extracellular concentrations of dopamine, which in turn increases dopaminergic neurotransmission and creates feelings of pleasure or even euphoria. A dopamine reuptake inhibitor has a number of medical applications.
But not all drugs increase dopamine levels in the brain in the same way. 1  Some substances imitate natural neuromediators and take their place on their receptors. 2  Other substances increase the secretion of natural neuromediators. 3  Still other substances block a natural neuromediator.
