Meanwhile, when they were listening to prayers that they thought were spoken by regular people not much happened. But for the religious folks (but not the non-religious folks):
Parts of the prefrontal and anterior cingulate cortices, which play key roles in vigilance and skepticism when judging the truth and importance of what people say, were deactivated when the subjects listened to a supposed healer.
So when this group of people were told that someone with special spiritual powers (rabbi's anyone?) was saying something, the parts of their brain that are responsible for skepticism SHUT OFF. Now that explains a lot...like how my mother, who is one of the most skeptical people I know 95% of the time, just seems to have a giant hole in her skepticism when it comes to anything her rabbi says. She seems to have passed the skepticism on to me, but not the belief part. Maybe it's genetic- I just don't have the brain for religiosity.
