There are on the order of a quadrillion (1015) connections in the neocortex, yet only about 25 million bytes of design information in the genome (after lossless compression),16 so the connections themselves cannot possibly be predetermined genetically. It is possible that some of this learning is the product of the neocortex’s interrogating the old brain, but that still would necessarily represent only a relatively small amount of information. The connections between modules are created on the whole from experience (nurture rather than nature).
