Study Finds Brain Stimulation Makes People Less Selfish

Scientists have shown that mild electrical stimulation to specific brain regions can temporarily make people behave more generously, highlighting a direct link between brain activity and altruistic decision-making, according to a report by BBC News.

The study, conducted by researchers at the University of Zurich, involved 44 volunteers who were asked to divide money between themselves and an anonymous person.

While participants made their decisions, researchers applied mild electrical stimulation to brain areas linked to empathy and decision-making, leading participants to share more money.

Lead researcher Christian Ruff said the changes in behavior were modest but consistent, showing a measurable increase in willingness to give.

The findings, published in PLoS Biology, suggest potential future applications for treating disorders that affect social behavior.

Researchers noted that the effect of a single stimulation session was temporary and that lasting behavioral change would require repeated sessions, similar to physical exercise.

Co-author Jie Hu of East China Normal University said the study establishes cause and effect, showing that altering communication within a brain network can influence how people share resources.

Participants described the stimulation as mild and did not feel it directly influenced their decisions, suggesting the behavioral changes occurred subconsciously.
