Highlights: Serotonin and dopamine had distinct effects on decisions to harm self versus others •Computational models revealed a hyperaltruistic preference to harm self over others •Pharmacological enhancement of serotonin increased harm aversion for self and others •Pharmacological enhancement of dopamine reduced hyperaltruism [1] http://www.sciencedaily.com/releases/2010/02/100201171517.htm http://www.sciencedaily.com/releases/2010/02/100201171517.ht...
