Neurologist VS Ramachandran explains the case of split-brain patients with one hemisphere without a belief in a god, and the other with a belief in a god. (Clip taken from talk at 2006 Beyond Belief Conference, link below)

More information about patient "L.B." referenced in this video:
The "theist-atheist" is "L.B.," who underwent section of the corpus callosum and anterior and hippocampal commissures in 1963, when he was 12 years 11 months old: https://www.academia.edu/6313681/Role_of_the_Commissures_in_Interhemispheric_Temporal_Judgments?auto=download
He was one of the two most tested split-brain patients in history: books.google.com/books?id=fROW4vqDGvEC&lpg=PA362&ots=76ZZWaNOFQ&dq=Ramanchandran%20%22patient%20LB%22&pg=PA372#v=onepage&q&f=false
You probably are already familiar with a paper about L.B.'s perception of a line-motion illusion: https://www.academia.edu/17444018/Hemispheric_integration_and_differences_in_perception_of_a_line-motion_illusion_in_the_divided_brain?auto=download
When L.B. was shown Penrose's impossible triangle (a visual anomaly) in one visual field and then the other, the anomaly was only noticed when the triangle was presented to the left visual field (or right hemisphere): http://ion.uwinnipeg.ca/~s…/research/smith04_b&c_anomaly.pdf
"Unlike most split-brain patients, L.B. demonstrates unusually effective ipsilateral motor control of both hands": books.google.com/books?id=fROW4vqDGvEC&lpg=PA362&ots=76ZZWaNOFQ&dq=Ramanchandran%20%22patient%20LB%22&pg=PA372#v=onepage&q=l.b.&f=false
L.B. is also one of three unusual split-brain subjects whose normally silent Right Hemisphere can "respond verbally to stimuli" [from what I have read elsewhere, that means one or two word answers]: books.google.com/books?id=KXsfAvtgGTAC&lpg=PA636&ots=ckfydo_Eby&dq=Ramanchandran%20%22patient%20LB%22&pg=PA327#v=onepage&q&f=false
"Ramanchandran (2003)... describes a study that showed that the non-verbal right hemisphere of a split-brain patient can lie: for instance after receiving instructions from researcher A ("to lie" to the patient (non-verbally) signed the wrong answer to researcher B. They also tested the personality and aesthetic preferences of the two hemispheres' 'selves' by training the right hemisphere to communicate 'yes' or 'no,' or 'I don't know' non-verbally by picking one of three abstract shapes with the left hand, and received surprising results that showed the two hemispheres can simultaneously hold contradictory views. For example, in patient LB the left hemisphere said it believed in God whereas the right hemisphere insisted that it was an atheist!: books.google.com/books?id=ISjaYUyykgsC&lpg=PA117&ots=_MeJw3eK9u&dq=Ramachandran%20split-brain%20atheist&pg=PA117#v=onepage&q&f=false
"Imagine our surprise when we noticed that in patient LB the left hemisphere said it believed in God whereas the right hemisphere signaled that it was an atheist. The inter-trial consistency of this needs to be verified but the very least it shows that the two hemispheres can simultaneously hold contradictory views on God." Ramanchandran, 2003 books.google.com/books?id=VZ7CBQAAQBAJ&lpg=PA13&ots=cGstf3nj5p&dq=Ramanchandran%20%22patient%20LB%22&pg=PA14#v=onepage&q&f=false
[...]
Someone also took a look at the humor of split-brain patients L.B. ["Philip"]and N.G. ["Linda"] since in both cases the right hemispheres was unusual in being able to "respond verbally to stimuli." books.google.com/books?id=3XPNDQAAQBAJ&lpg=PA217&ots=AyHT_CXhFa&dq=Ramanchandran%20%22patient%20LB%22&pg=PA217#v=onepage&q&f=false
"Zaidel once asked Philip [=L.B. according to his endnote?] a series of questions directed to his left and right hemispheres and found that the two sides of his brain had different personalities and outlooks on life. His left hemisphere experienced relatively low self-esteem while his right hemisphere [the "atheist" hemisphere according to Ramachandran] saw itself rather positively. The right side also experienced greater loneliness and sadness. Another split-brain patient's right hemisphere was particularly influenced by childhood memories of being bullied, even though his left hemisphere denied finding such experiences disturbing." books.google.com/books?id=3XPNDQAAQBAJ&lpg=PA217&ots=AyHT_CXhFa&dq=Ramanchandran%20%22patient%20LB%22&pg=PA169#v=onepage&q&f=false
