Are brain studies and the concept of mind sufficient to account for the openness of man to God?

Scientific studies of religious experience have become fashion since about 20 years. Object of these studies are common cultural patterns of beliefs, their possible adaptive advantages and their neural correlate. It is all but uncommon to hear in this context that the brain of the human being is ‘wired to believe’. But how can we interpret these investigations? Are they sufficient to account for the religious phenomenon? If they are, does this entail a proof that God is an invention of our brains? What objective relevance can these studies have for religious faith?
