Banned because the neuroanatomy is the important part. Who cares what the mass of the organ is if its function continues to alter significantly. Point is that we should wait and see how he is about when he finishes college.
Banned for being a dreary materialist and having no appreciation for emergent properties of whole systems.
Sure, the neuroanatomy is an important part, but if we've learned anything about the 'hardware' approach to biology in recent decades it's that how you use it is also very important. This applies both to the esoteric details of epigenitics and the equally esoteric business of understanding the human mind as an organic chemical process that can span around ten decades.
