Separating our personality & intellect from what we consider our "spirit" has always been a tricky thing to define from a theological point of view. Scientifically, it's easy. There is no "spirit." There is only body and it is either living or dead. With that as a lead-in, I just read an interesting article about the "God Spot" in our brain. You can read the article here: (Scientists Locate "God Spot"
). It's not very long.
The overall gist is that brain scans show our brain has higher thought patterns operating when when we are thinking about "religious statements." This suggests that there is no single "God Spot" in our brain - a sole location where religious thought occurs.
The researchers draw the conclusion that this "suggests that religion is not a special case of a belief system, but evolved along with other belief and social cognitive abilities." Not surprisingly, the research identified that other active parts of our brain when we think religious thoughts are the areas controlling metaphor and abstract thoughts.
A couple of unanswered research questions remain. The first is a sort of "chicken or egg" question. Were the religious thought functions central in early cultures or did they evolve with other social functions? The second is whether or not the brain reacts differently for other religious cultural thought. Apparently the study was done solely on Western Christian adherents.
So - there you have it. There is no single "God Spot" in the brain.
Here's my question to you: How closely tied is our brain to our spirit?
