I don't know about that. We are walking on thin ice when we pigeon hole God so that have a neat, clean, packagable way of understanding the Trinity. We know from the bible that there are three PERSONS of the trinity, and that Jesus was not just praying to his ego. 3 distinct persons, and 1 triune God. God the Father, the son, and the Holy Ghost. There is a delicate economy that exists among the persons of the trinity, creator, judge, sacrifice, comforter. I think there are serious problems with the ideas presented. IT could be a metaphor, but the parts of the brain seem too distinct for me. I stick with the father-son-servant metaphor. The I know I would love to understand the mysteries like the trinity and predestination/freewill. But I think the best is to stick with biblical or authoritative texts that have come out tof the church and live with the mystery. He is God and we are not.
Again, check out the catechisms.
