NEURON

SYNAPSE

Once released, dopaminetravels across a gap between nerve cells, called a synapse, and

binds to a receptoron a neighboring nerve cell (also called a neuron). This sends a signal

to that nerve cell, which produces a good feeling.

Under normal conditions, once the dopamine sends that signal it is reabsorbed by

the neuron that released it. This reabsorption happens with the help of a protein

called the dopamine transporter.
