There is a major collection of axons connecting the two sides of the cerebral cortex, the corpus callosum. It is not clear why any one part of the brain would be particularly important for connecting the non-material Phantom Core to the physical structures of the brain, but the Lyricus Teaching does emphasize the link between consciousness and the soul. The corpus callosum allows us to coordinate brain functions that are differently distributed between the two sides of the brain....probably most things we can become aware of have a "reflection" in the data stream of the corpus callosum.
