Summary:

- This article discusses the use of transcranial direct current stimulation (tDCS), a non-invasive brain stimulation technique, to potentially reduce selfish behavior and increase prosocial behavior.

- Researchers found that applying tDCS to the dorsolateral prefrontal cortex, an area of the brain involved in decision-making and social cognition, can lead to more generous and altruistic behavior in economic games.

- The article suggests that this brain stimulation technique could have implications for understanding the neural mechanisms underlying social decision-making and potentially be used as a tool to promote more cooperative and prosocial behavior in society.
