ELI5: When people say "dopamine is released," where exactly is it released from and where to does this "released" dopamine go to?

Your brain is made up of nerve cells called neurons. These cells kind of look like fried eggs with long tendrils coming off of them. These tendrils connect to other neurons. The place where they connect is called a synapse.

Neurons don't directly touch at the synapse. There's a small gap. In order to send signals across the gap they release chemicals called neurotransmitters. Depending on which neurotransmitter is released there will be different reactions. 

Dopamine is one of those neurotransmitters.
