7: Localization of opioid binding sites
When a person injects heroin or morphine, it too, travels quickly to the brain. Point to the areas where opioids concentrate. The VTA, nucleus accumbens, caudate nucleus and thalamus are highlighted. The opioids bind to opioid receptors that are concentrated in areas within the reward system. Indicate that the action of opioids in the thalamus contributes to their ability to produce analgesia.
