Non-random neurogenic niche construction

Leprosy Reprograms Body’s Cells

Excerpt: “The bacteria transformed the cells, turning off genes that were expressed in mature Schwann cells and turning on genes associated with earlier stages of cell development. The cells became immature and, like certain kinds of stem cells found in bone marrow and other tissues, could now turn into bone and muscle cells.”

The neurobiological consequence of predating or grazing

Excerpt: “While C. elegans feeds exclusively on bacteria, P. pacificus is able to switch its behaviour to prey on other worms if bacterial food gets scarce. These differences are reflected in the number and position of neuronal synapses.”

My comment: In my model, ingested bacteria could epigenetically cause the transition from “grazing” in C. elegans to “predation” in  P. pacificus via the common molecular mechanisms of nutrient-dependent ecological niche construction and pheromone-controlled social niche construction that leads to neurogenic niche construction associated with species-specific behavior.

The transition from grazing to predation appears to exemplify what is common to all species in my model: nutrient chemical-dependent pheromone-controlled adaptive evolution.

 

About James V. Kohl 1307 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.
