Research scientists at MIT have been studying the right temporo-parietal junction (TPJ) region of the brain that seems to be involved in judging the behavior of other people. With the help of transcranial magnetic stimulation (TMS) applied to the region, they were able to affect the moral conclusions that people reached when analyzing the actions of others.
From MIT news office:
The researchers used a noninvasive technique known as transcranial magnetic stimulation (TMS) to selectively interfere with brain activity in the right TPJ. A magnetic field applied to a small area of the skull creates weak electric currents that impede nearby brain cells’ ability to fire normally, but the effect is only temporary.
In one experiment, volunteers were exposed to TMS for 25 minutes before taking a test in which they read a series of scenarios and made moral judgments of characters’ actions on a scale of one (absolutely forbidden) to seven (absolutely permissible). Read more »
