Uffe Schjødt examined the neuroscience of prayer:
Surprisingly, considering God’s postulated invisibility, omnipresence, omnipotence, and omniscience, we found that conversing with God was not associated with regions that process abstract concepts. Rather, we found a marked pattern of activity in four regions that typically activate when humans relate to other humans. … One might ask if these findings, then, are evidence that God is just an illusion, an imagined friend that always listens in times of distress? Or may they in fact be proof that God affects us even at the level of brain function?
