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