One way the brain compensates is to reduce the number of dopamine receptors at the synapse. In addition, sending neurons increase their number of dopamine transporters, more quickly clearing dopamine from the synapse. These changes make the brain less responsive to the drug, but they also decrease the brain’s response to natural rewards. These brain scans highlight dopamine receptors, with areas of highest density shown in red.
