The release of dopamine from the mesolimbic pathway into the nucleus accumbens regulates incentive salience (e.g. motivation and desire for rewarding stimuli) and facilitates reinforcement and reward-related motor function learning; [3] [4] [5] it may also play a role in the subjective perception of pleasure.
Some dopamine receptors are located in the walls of arteries, where they act as a vasodilator and an inhibitor of norepinephrine release from postganglionic sympathetic nerves terminals (dopamine can inhibit norepinephrine release by acting on presynaptic dopamine receptors, and also on presynaptic α-1 receptors, like norepinephrine itself). [75]
The dopamine neurons of the dopaminergic pathways synthesize and release the neurotransmitter dopamine. [2] [3] Enzymes tyrosine hydroxylase and dopa decarboxylase are required for dopamine synthesis. [4] These enzymes are both produced in the cell bodies of dopamine neurons. Dopamine is stored in the cytoplasm and vesicles in axon terminals.
The release of β-endorphin has been postulated to contribute to the phenomenon known as "runner's high". [ 40 ] [ 41 ] However, several studies have supported the hypothesis that the runner's high is due to the release of endocannabinoids rather than that of endorphins. [ 42 ]
Dopamine is a crucial neurotransmitter involved in our brain’s reward system. It plays a central role in motivation, as well as executive function (which includes attention, ...
Amphetamine, the prototypical monoamine releasing agent, which induces the release of dopamine and norepinephrine. [1]A monoamine releasing agent (MRA), or simply monoamine releaser, is a drug that induces the release of one or more monoamine neurotransmitters from the presynaptic neuron into the synapse, leading to an increase in the extracellular concentrations of the neurotransmitters and ...
