Altruistic punishment is punishing violators of social norms when there is personal cost. The test: whether or not to punish the financial advisor. The subjects: (1) control group of people without parkinson"s disease (pd) (26) Conclusion: dopamine has a role in punishment decisions in pd patients with icb. Altruistic punishment has been shown to reduce unjust behaviour within groups. In pd, dopamine innervation of dopamine is depleted. The controls were from the family of the pd patients. Authors were motivated to pursue this research because they believed that pd+icb patients. Imaging shows that the brain area responsible for mediating punishment is the caudate nucleus in the dorsal striatum, and altruistic punishment is specialized in the ventral caudate. Also, the prefrontal cortex is responsible for processing fair and unfair behaviours. (difficulty with motor movements). Some pd patients who need to undergo long-term dopamine treatment experience biological icb (pathological gambling, hypersexuality, binge eating, and reckless generosity) because dopamine provokes this behavior.
