“God helmet” uses weak magnetic fields to stimulate the right temporal lobe to create the illusion of a presence with the person wearing it

The “God spot” does not prove that religion is “all in our heads”; at most, it shows that a certain spot in our brain interacts with religious feeling in some way, and that religious feeling can be counterfeited in certain situations. Neither of those things should come as a surprise to Christians.
While these findings are interesting, they should in no way threaten Christians’ faith. We already believe that God has created us to be embodied souls (trichotomists may feel free to insert the spirit at this point); we are unified creatures, in whom material and immaterial join and relate. If I have a thought, it is mediated through the brain. If I have an emotion, it is mediated through the brain. (By “mediated,” I simply mean that there is brain activity in conjunction with these other acts.) If my body and spirit are joined in the way that the Bible seems to indicate, then why wouldn’t any “spiritual” experience also have some related physical manifestation, even if it is only the release of certain neurotransmitters? We are neither Gnostic nor dualist, and the “God spot” is probably what we should have expected to find if indeed God made man out of the dust of the ground, breathed into his nostrils the breath of life, and made him a living soul.

Faith is obeying when you can't even imagine how things might turn out right.
