Bee research, human sweet perception, human pheromones, and metabolic disorders

A diet-reponsive neurogenic niche links nutrient chemical intake to receptor-mediated brain development in mammals. Glucose regulates the hormone secreting nerve cells in this niche, which links it and other nutrient chemicals to levels of luteinizing hormone (LH) and brain development.

Brain Activation Areas of Sexual Arousal with Olfactory Stimulation in Men

There is no direct link from visual or auditory stimuli that would explain any likelihood that spectral stimuli could classically condition the response to nutrient chemical associated with food odors.

Human pheromones: Olfaction, odor receptors, learning, memory, mood, brains and behavior

The idea that ecological niches and social niches are the determinants of neurogenic niches, like those that develop with exposure to food odors and social odors, is one that is important to consider whether we intend to look at pharmacogenomics or to better understand the development of human behavior in the context of epigenetic effects of odors on brain development.

Human pheromone- and nutrient-dependent brain development and behavior

…model organisms make clear the extension of the concept to nutrient chemical and pheromone-dependent neurogenic niches, human brain development, and individual differences in behavior.

Human pheromones and brain development

the epigenetic effects of chemicals from our sensory environment on GnRH are probably essential to the development of an evolved brain and behavior involved in seeking out proper nutrition and reproductively “fit” mates.

Human Pheromones may influence brain chemistry into adulthood

Nutrition is such an obvious epigenetic influence on brain development that it should be somewhat clear that social odors would also be a powerful influence on brain development and behavior.

Human Pheromones and sex differences in brain maturation

The effect of GnRH on secretion on luteinizing hormone/follicle stimulating hormone ratios and steroidogenesis, links social odors to brain maturation across species of mammals, as well as vertebrates. Experience-dependent brain-directed behaviors should be as variable as would be expected by the association between food odors and food preferences.

Progress in brain research (e.g., starting over)

I’m not sure where researchers first strayed from the gene, cell, tissue, organ, organ-system pathway, but I am happy to see evidence that research may get back on the path that directly links sensory input to brain function and behavior.

The Mind’s Eyes: Mindful modeling of brain directed behavior

Food odors drive behaviors associated with food acquisition; social odors (called pheromones) drive behaviors associated with mate acquisition.
