Your scientific theories are as secure as trying to put into me that I would agree that Downs Syndrome children have no souls.  Last I heard, they they do have functioning cerebral cortices and minds.  IQ is not a determinate of who or what has a mind or a soul.  As a neuroscientist and one that has taken more than simple embryology, you simply are pushing your hypothesis without any true observation or proof of truth.  Your ideas about neuro-electric energy are simply not observed.  I, as a Catholic, do not at all like abortion, but we must not try to guide people by using false scientific concepts.  This would be as bad as authoritarian religious ideas.
