Science Neuro-news: brain stimulation and money distribution

Science 4 October 2013 - Vol. 342 no. 6154 - p. 25: 
Neuroscience - Brain Stimulation Sparks "Machiavellian" Choices. 

It is a tipical neuro-economics' study!  

People have played money-sharing games countless times to help economics researchers probe issues of altruism, cooperation, and fairness. Now, a new study shows that a weak electrical current directed toward a patch of brain on the right side of the head can trump a person's normal impulses on how to distribute money fairly. Depending on the current's nature, participants in such a game shared more or less money. Thus the work confirms that the brain region, the right lateral prefrontal cortex, helps to guide such choices.
