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.
When adenosine receptors are normally activated, they tend to cause sedative effects, such as reducing your heart rate and suppressing the release of other neurotransmitters (including glutamate and dopamine). But caffeine may work by binding to (and blocking) adenosine receptors in your brain and throughout your body. And once those adenosine receptors are blocked, the other neurotransmitters get to hang out and excite your system. Fun fact: This same mechanism is thought to play a part in caffeine's addictive properties.
