Nature reports (gated):
Removing part of the brain can induce inner peace, according to researchers from Italy. Their study provides the strongest evidence to date that spiritual thinking arises in, or is limited by, specific brain areas. To investigate the neural basis of spirituality, Cosimo Urgesi, a cognitive neuroscientist at the University of Udine, and his colleagues turned to people with brain tumours to assess the feeling before and after surgery. Three to seven days after the removal of tumours from the posterior part of the brain, in the parietal cortex, patients reported feeling a greater sense of self-transcendence. This was not the case for patients with tumours removed from the frontal regions of the brain.
Sager has a good summary of the study.
