A belief in God is deeply embedded in the human brain, which is programmed for religious experiences, according to a United States study.

Scientists searching for the neural "God spot", which is supposed to control religious belief, believe several areas of the brain form the biological foundations of religious belief.

The researchers said their findings supported the idea that the brain had evolved to be sensitive to any form of belief that improved the chances of survival, which could explain why a belief in God and the supernatural became so widespread in human evolutionary history.


"Our results are unique in demonstrating that specific components of religious belief are mediated by well-known brain networks and they support contemporary psychological theories that ground religious belief within evolutionary-adaptive cognitive functions."

Scientists are divided on whether religious belief has a biological basis.


Others have suggested that religious belief is a side effect of a wider trait in the human brain to search for coherent beliefs about the outside world. Religion and belief in God, they argue, are just a manifestation of this intrinsic, biological phenomenon that makes the human brain so intelligent and adaptable.

The latest study, published in the journal Proceedings of the National Academy of Sciences, involved analysing the brains of volunteers, who had been asked to think about religious and moral problems and questions. For the analysis, researchers used a functional MRI machine, which can identify the most active regions of the brain.

They found that people of different religious persuasions and beliefs, including atheists, tended to use the same electrical circuits in the brain when solving a moral conundrum as well as when dealing with issues related to God.

The study found that several areas of the brain were involved in religious belief, one within the frontal lobes of the cortex - which are unique to humans - and another in the more evolutionary-ancient regions deeper inside the brain, which humans share with apes and other primates, Professor Grafman said.

"There is nothing unique about religious belief in these brain structures. Religion doesn't have a 'God spot' as such, instead it's embedded in a whole range of other belief systems in the brain that we use every day," Professor Grafman said.


An early contender was the brain's temporal lobe, a large section that sits over each ear, because temporal-lobe epileptics suffering seizures in those regions frequently reported intense religious experiences.


This work was followed by a study where scientists tried to stimulate the temporal lobes with a rotating magnetic field produced by a "God helmet". Michael Persinger, from Laurentian University in Ontario, found he could artificially create the experience of religious feelings - the helmet-wearer reported being in the presence of a spirit or having a profound feeling of cosmic bliss.

Dr Persinger said about eight in every 10 volunteers reported quasi-religious feelings when wearing his helmet. However, when Professor Richard Dawkins, an evolutionist and renowned atheist, wore it during the making of a BBC documentary, he famously failed to find God, saying the helmet only affected his breathing and his limbs.




He said that the latest study suggested the brain was inherently sensitive to believing in almost anything if there were grounds for doing so, but when there was a mystery about something, the same neural machinery was co-opted in the formulation of religious belief.
