Do You Have a “Selfish Prefrontal Cortex”?Do you tell “white lies” only for selfish motives?
A recent neuroscience paper claims to determine whether your motives are selfish: You may think a little white lie about a bad haircut is strictly for your friend’s benefit, but your brain activity says otherwise. Distinct activity patterns in the prefrontal cortex reveal when a white lie has selfish motives, according to new research published in Journal of Neuroscience. White lies — formally called Pareto lies — can benefit both parties, but their true motives are encoded by the medial prefrontal cortex (MPFC). This brain region computes the value of different social behaviors, with some subregions focusing on internal motivations and others on external ones. Kim and Kim predicted activity patterns in these subregions could elucidate the true motive behind Read More ›
