Sackler Colloquium: Effects or AFFECTS on Behavior

Arthur M. Sackler Colloquium of the National Academy of Sciences,

Epigenetic Changes in the Developing Brain: Effects on Behavior,”

held March 28–29, 2014, at the National Academy of Sciences in Washington, DC. The complete program and video recordings of most presentations are available on the NAS website.

I reiterate: the title is: Epigenetic changes in the developing brain: Effects on behavior

I was taught that the epigenetic landscape must be linked to physical landscape of DNA in organized genomes of invertebrates and vertebrates via gene activation in hormone-secreting nerve cells of tissue in the brain.

I was taught that nothing but the gene, cell, tissue, organ, organ system pathway could link hormone-organization and hormone-activation from the sensory environment to AFFECTS on behavior.

The title of the Sackler Collogquia seems to suggest that experts on DNA methylation, histone chemistry, and the emerging field of non-coding RNAs may not know the difference between EFFECTS of sensory input on hormones and the AFFECTS of hormones on behavior.

That may be why some researchers still don’t understand the fact that “Feedback loops link odor and pheromone signaling with reproduction

Evolutionary theorists skip the feedback loops and claim that mutations somehow lead to evolved biodiversity. I find it impossible to believe in their theories.

I know that food odors epigenetically effect GnRH secretion and so do species-specific pheromones. The epigenetic effects on GnRH link the sensory environment to behavior in all vertebrates. Behavior is nutrient-dependent.

RNA-directed DNA methylation and RNA-mediated events link nutrient uptake to amino acid substitutions that differentiate cell types via changes in GnRH secretion and its downstream affects on species-specific behaviors and morphologies.

Was I taught to believe in pseudoscientific nonsense about the bio-physically constrained chemistry of protein folding and conserved molecular mechanisms that link epigenetic effects on hormones to affects on behavior? Alternatively, were you taught to believe in pseudoscientic nonsense that links mutations to morphological and behavioral phenotypes via evolution.

See also with my emphasis: Thus, a future research goal should be to provide a neurobiological framework for understanding positive health, positive effect, and self-efficacy and self-esteem and how these components are biologically embedded in a nurturing environment by epigenetic influences, including effects on reactive alleles in the genome. CORRECTION: The authors note that on page 17184, right column, first paragraph, line 4, “effect” should instead appear as “affect.”

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.
