Neuronal copy number variation (CNV) and the brain

Science 1 November 2013: Vol. 342 no. 6158 p. 577 DOI: 10.1126/science.342.6158.577

The introduction to this special issue is: “Connection, Connection, Connection.”  (Here’s the link to the issue’s contents.)

Excerpt: “This year’s neuroscience special issue is devoted to general and also several more specific aspects of research on connectivity in the brain.”

My comment (accepted for publication to the Science site on 11/4/13) : Re: Mosaic Copy Number Variation in Human Neurons.

The neuronal copy number variation (CNV) can be traced to its origins in yeasts, when epigenetically-effected CNVs enable self vs non-self recognition at the advent of immune system function and sexual reproduction, albeit sans neurons.

Olfactory/pheromonal input is subsequently associated with alternative splicings that link the epigenetic ‘landscape” to the physical landscape of DNA in the organized genome of species from microbes to man via CNVs. During adaptive evolution the CNVs in neurons are directly linked from olfactory/pheromonal input via ecological, social, neurogenic, and socio-cognitive niche construction. For example, neuronal niche construction in nematodes proceeds across species via conserved molecular mechanisms required for the thermodynamics of seemingly futile nutrient-dependent cycles of protein synthesis and degradation to species-specific pheromones. Pheromones control the physiology of reproduction and help to control nutrient-dependent organism-level thermoregulation.

In a mammal, see for example: Odorant receptor gene choice and axonal wiring in mice with deletion mutations in the odorant receptor gene SR1. However, see also my ISHE Summer Institute poster session for details that eliminate mutations from further consideration in adaptive evolution. To do that I used examples from nematodes, insects, other mammals, and a human population that arose in what is now central China during the past ~30,000 years.

Non-random experience-dependent adaptive evolution occurs due to a thermodynamically controlled single base pair change and nutrient-dependent amino acid substitution best exemplified in the mouse model via what is neuroscientifically known about nutrient-dependent pheromone-controlled reproduction.

Note: I have made four attempts to post this comment to the ISHE’s human ethology yahoo group, and the moderator, Jay Feierman, is blocking the added response to Clarence ‘Sonny’ Williams post about the special issue on neuroscience.

Addendum: …as weird as a microbe with a human insulin gene may seem, it still uses the ancient code that life has relied on for billions of years.

Within one week of science news, researchers attempting to make scientific progress have been offered the opportunity to select neuroscience or nonsense. I mention this because there is no model for the snake-centric evolution of the human brain and behavior. For contrast, every model organism on this planet attests to the fact that snake-centric evolution is the most ridiculous theory ever to be discussed among scientists or those who are scientifically illiterate evolutionary theorists. See, for example: Afraid of Snakes? Your Pulvinar May Be to Blame.

Ask what story was of most interest to any evolutionary theorist you know, and remember that theorists are probably teaching your children, grandchildren, and great-grandchildren to ignore biological facts and animal models that link the epigenetic ‘landscape’ to nutrient-dependent pheromone-controlled adaptive evolution in species from microbes to man.

This comment to the ISHE’s human ethology yahoo group was approved after the second attempt, and I will address it more thoroughly after I have acquired the reprint of the latest work from senior author Bradley Cooke.


Given your current understanding of how connections in the brain are involved in behavior, please try to put the following articles (or any articles published anywhere else in the past decade) into the context of mutation-initiated natural selection, or snake-centric evolution of the human brain via molecular mechanisms that led to visual primacy in humans.

My current understanding of receptor-mediated changes in brain connections that vary in males and females is that they are the result of a direct link from the epigenetic ‘landscape’ to the physical landscape of DNA in the organized genomes of species from microbes to man (sans mutations).  One of the co-authors of the papers linked above sponsored me for membership in the Society for Neuroscience. I think that he may help me make a point that I’ve been trying to make about epigenetic effects. For comparison, please try to make a point about mutation-initiated natural selection and how it leads to changes in neuronal connections, which now includes the role of specific changes in specific neurons of the human brain.



About James V. Kohl 1308 Articles
James Vaughn Kohl was the first to accurately conceptualize human pheromones, and began presenting his findings to the scientific community in 1992. He continues to present to, and publish for, diverse scientific and lay audiences, while constantly monitoring the scientific presses for new information that is relevant to the development of his initial and ongoing conceptualization of human pheromones. Recently, Kohl integrated scientific evidence that pinpoints the evolved neurophysiological mechanism that links olfactory/pheromonal input to genes in hormone-secreting cells of tissue in a specific area of the brain that is primarily involved in the sensory integration of olfactory and visual input, and in the development of human sexual preferences. His award-winning 2007 article/book chapter on multisensory integration: The Mind’s Eyes: Human pheromones, neuroscience, and male sexual preferences followed an award winning 2001 publication: Human pheromones: integrating neuroendocrinology and ethology, which was coauthored by disinguished researchers from Vienna. Rarely do researchers win awards in multiple disciplines, but Kohl’s 2001 award was for neuroscience, and his 2007 “Reiss Theory” award was for social science. Kohl has worked as a medical laboratory scientist since 1974, and he has devoted more than twenty-five years to researching the relationship between the sense of smell and the development of human sexual preferences. Unlike many researchers who work with non-human subjects, medical laboratory scientists use the latest technology from many scientific disciplines to perform a variety of specialized diagnostic medical testing on people.
