“The rate at which [new neurons] incorporate is dependent upon experience,” Gage says.
My comment: The experience-dependent de novo creation of olfactory receptor genes is the basis for the following representation of biologically-based cause and effect:
Feedback loops link odor and pheromone signaling with reproduction
Virus-perturbed nutrient-dependent RNA-mediated protein folding biochemistry is the clearest link from nutrient-stress and social stress to brain pathology and other pathology. The pathology is linked to viral microRNAs that steal the energy provided by nutrient-dependent microRNAs, which is essential for RNA-mediated DNA repair during the life history transitions of all living genera.
Neo-Darwinian theorists tend not to comment on that fact. Perhaps the problem is Eugene Koonin’s admission that: “The entire evolution of the microbial world and the virus world, and the interaction between microbes and viruses and other life forms have been left out of the Modern Synthesis…”
