Questions for Victor Reppert and The Argument From Reason

If you examine any two things you can find both similarities and differences. The organ known as the human brain (such as scientific experts presently know and examine it under their microscopes and via physical experiments), is of course different from the fullness of the mental world of our minds that we each experience. (But then, dissecting anything, like a frog, doesn't give you the fullness of that frog or its inner world either.)

Also, I agree with you that the connections linking our thoughts in long chains do not appear to be of the same kind of connections linking, say, actual metal chains. (However, we do know that the human brain like all other brains in nature features endless chain reactions of an electro-chemical sort. And the pathways of such electro-chemical activity are becoming more well known to scientists who are mapping them out.)

Question: If one is a "substance dualist" and believes that mental reasoning abilities are supernatural and enter the brain from outside the natural world, which part of the brain picks up these invisible signals from the supernatural world? In other words, if supernatural signals enter the brain at some point, what is that point? Or, if supernatural signals enter the brain at multiple points, then why can't both halves of a split-brain patient's brain "know" what the other half is thinking? Why can't one half of a split-brain patient "read the mind" of the other half of that same individual's brain? Why do split-brain patients, during such experiments, appear as if they were carrying on two separate thoughts and willing two different decisions at the same time?

Also, why the endless chain reactions of an electro-chemical sort that continue unabated between neurons and between entire sectors of the brain, traveling from one sector of the brain to the other and back again if the brain is being directed not by those reactions but by a supernatural force that is able to enter the brain and direct multiple brain sectors simultaneously?
