It certainly sounds like the genetic changes are limited to the brain itself. Perhaps there is some kind of extra DNA scratch space allotted to cranial nerve cells. I understand that psilocybin, a phosphorylated serotonin-like neurotransmitter found in fungal mycelia, may have evolved as a phosphorous bank for all the DNA needed in spore production. The structure of fungal mycelia closely approximates that of the brains found in the animal kingdom, which may have evolved from the same or some shared point. Then we see how the brain can be viewed as a qualified, indeed purpose-built DNA recombination factory! Fungal mycelia could be approaching all this from the opposite direction, doing DNA computation incidentally so as to perform short-term weather forecasts and other environmental calculations, simply because there is so much of it about for the next sporulation.
