As a testament to humankind's everlasting quest for knowledge and understanding of the self, a number of scientific studies in the recent times have examined the elusive relationship between the human brain and that fountainhead of human emotion and passion, namely, Religion. There have been studies on neurological correlates of religious experiences and spiritual practices, such as meditation and prayer; many studies have looked at both acute and chronic effects of such practices in relation to brain function. A recent study along the same lines, published by Owen et al. of Duke University, in PLoS One on March 30, 2011, has attempted to link religious factors with changes in a specific brain region, the hippocampus, using functional magnetic resonance imaging (fMRI) techniques.
