Brain behind the Selfish and Selfless

Scientist's untiring endeavor to unravel the mysteries in the gray matter has offered an insight into a trait so common and natural to humans, and needs no introduction - SELFISHNESS. Bewildering all the same, why are some people more selfish than the rest of us? While some others believe in being the epitome of selflessness!

Scientists have clued in on a tiny piece of tissue at the front of the brain, termed as the dorsolateral prefrontal cortex. Studying a game that embodied "fairness", scientists discovered that the right region of the brain had the capacity to control the tendency to be selfish.

To analyze further, scientists used electric shock to short circuit the area. This created an insatiable thirst in the subjects for making money even from unworthy deals. Although they were in a position to comprehend the nuances of the deal, they were unable to control their urges. This experiment led to the understanding that the cortex plays a crucial role in dictating social behavior.
