Effects of pheromones attributed to touch (in mice)

Paternal mice bond with their offspring through the power of touch Prior work (1) from two of these same authors correctly attributed changes in the production of new brain cells to the effect of pheromones on  neurons in the olfactory bulb that express gonadotropin-releasing hormone (GnRH), which send projections to the hypothalamus. This results in the release of luteinizing hormone and follicular-stimulating hormone (FSH) by the anterior pituitary.  Together, LH and FSH control the release of steroid hormones, such as estrogen, that influence sexual behavior via effects on neurogenesis. Estrogen promotes the release of prolactin (PRL) and provides a regulatory feedback loop for LH and FSH release.

Looking at the downstream effects of GnRH on other hormones, and then attributing effects on neurogenesis and behavior to these other hormones derails the logic of an well-established link from pheromones to behavior.

In the report linked above, the effect of pheromones is attributed to touch. Clearly, however, it is the effect of pheromones that stimulates the production of new brain cells, as has been detailed in other works, including at least one by Dr. Weiss and his colleagues.

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.
