Food odors and social odors

The convergence of findings detailed in these two recent publications (linked below) makes it harder to defend a model where attraction to androgenic physical features of human males depends on their automagically determined visual appeal. I’ve waited several years for publication of the paper by Lenochova et al., after I saw her preliminary poster presentation from an conference. The work by her and her colleagues supports our work with pheromone enhancement of natural body odor. If fragrance can enhance the appeal of natural body odor, we should be able to further enhance appeal by adding pheromones, as we have repeatedly shown.

Effects of fragrance are actually unconsious affects via their association with natural species-specific odors that differentially alter levels of luteinizing hormone and brain development in males compared to human females. Brain imaging tells that these unconscious affects are more important to the development of behavior than is conscious perception of visual input. Besides, there’s no animal model for effects of conscious perception on species-specific behavior.

Food odors and social odors

Nutrient chemicals up-regulate and pheromones down-regulate the complex calibration, standardization, and control of gene expression that is responsible for the development of ecological and social niches in species from microbes to man. The direct “epigenetic” effect of these “food” odors and “social” odors on intracellular signaling pathways is what makes these two types of chemical cues as important to understanding the development of human behavior as they are to understanding behavior in every other species. The honeybee is the model organism that has emerged for use to portray the involvement of sensory input from the environment in the development of human behavior. It may surprise some people to learn that the incentive salience of visual and auditory stimuli pales by comparison to that of olfactory/pheromonal input, but this neuroscientific fact would not come as a surprise to any other species of insect or mammal.

Social odors

Fragrance use does not merely mask their natural odor production, it adds to the appeal of men’s axillary odors. Could cultural practices associated with fragrance use contribute to the complex calibration, standardization, and control of genotype and phenotypic expression frequencies in different ancestral species and modern man? Can the biological basis of culture be found in the chemistry of social odors?

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.
