While religious faith remains one of the most significant features of human life, little is known about its relationship to ordinary belief at the level of the brain. Nor is it known whether religious believers and nonbelievers differ in how they evaluate statements of fact. Our lab previously has used functional neuroimaging to study belief as a general mode of cognition [1], and others have looked specifically at religious belief [2]. However, no research has compared these two states of mind directly. Methodology/Principal Findings
We used functional magnetic resonance imaging (fMRI) to measure signal changes in the brains of thirty subjects—fifteen committed Christians and fifteen nonbelievers—as they evaluated the truth and falsity of religious and nonreligious propositions. For both groups, and in both categories of stimuli, belief (judgments of “true” vs judgments of “false”) was associated with greater signal in the ventromedial prefrontal cortex, an area important for self-representation [3], [4], [5], [6], emotional associations [7], reward [8], [9], [10], and goal-driven behavior [11]. This region showed greater signal whether subjects believed statements about God, the Virgin Birth, etc. or statements about ordinary facts. A comparison of both stimulus categories suggests that religious thinking is more associated with brain regions that govern emotion, self-representation, and cognitive conflict, while thinking about ordinary facts is more reliant upon memory retrieval networks.
Conclusions/Significance
While religious and nonreligious thinking differentially engage broad regions of the frontal, parietal, and medial temporal lobes, the difference between belief and disbelief appears to be content-independent. Our study compares religious thinking with ordinary cognition and, as such, constitutes a step toward developing a neuropsychology of religion. However, these findings may also further our understanding of how the brain accepts statements of all kinds to be valid descriptions of the world.

Sam Harris (born 1967) is an American non-fiction writer, philosopher and neuroscientist. He is the author of The End of Faith: Religion, Terror and the Future of Reason (2004), which won the 2005 PEN/Martha Albrand Award, and Letter to a Christian Nation (2006), a rejoinder to the criticism his first book attracted. His new book, The Moral Landscape, explores how science might determine human values.
After coming under intense criticism in response to his attacks on dogmatic religious belief, Harris is cautious about revealing details of his personal life and history. He has said that he was raised by a Jewish mother and a Quaker father, and he told Newsweek that as a child, he "declined to be bar mitzvahed." He attended Stanford University as an English major, but dropped out of school following a life-altering experience with MDMA. During this period he studied Buddhism and meditation, and claims to have read hundreds of books on religion. In an August 21, 2009 appearance on Real Time with Bill Maher, Harris stated that he grew up in a secular home and his parents never discussed God. He has stated, however, that he has always had an interest in religion.
After eleven years, he returned to Stanford and completed a bachelor of arts degree in philosophy. In 2009, he obtained his Ph.D. degree in neuroscience at University of California, Los Angeles, using functional magnetic resonance imaging to conduct research into the neural basis of belief, disbelief, and uncertainty.
This is pretty fascinating. I'm not literate enough in all the language to completely understand some of the details, but the findings about parts of the brain being stimulated in regards to religious belief are pretty interesting. I have some questions (thoughts) about psycho-pharmacology and what could possibly be belief centers in the brain, but I'll wait till I re-read this again before just spouting out about things.
Sebuah kajian yang menarik walaupun saya tidak fasih langsung dengan hampir semua istilah yang digunakan.
Sebagaimana keupayaan menguasai bahasa tinggi yang dikatakan telah siap wujud di dalam diri setiap manusia (instilled), begitu juga lah dengan kepercayaan kepada Tuhan. Hasil kajian mendapati golongan kanak-kanak dan remaja mempercayai kewujudan Tuhan. Namun akibat pengaruh budaya dan faktor-faktor lain, pemikiran ini mungkin berubah apabila semakin meningkat dewasa.
More fascinating contributions to the nature of belief in general and some incremental steps and revolutionary work in the neuropsychology of religion.
I don’t have enough knowledge of math and science (specifically neuroscience and statistics) to fully understand what is being said… but I find what I manage to grasp interesting nonetheless.
