A neural circuit encoding sexual preference in humans Excerpt: We anticipate the identification of a core neural circuit for sexual preferences to be a starting point for further sophisticated investigations into the neural principles of sexual behavior and particularly of its aberrations. My comment: They link sexual orientation in yeasts to humans but fail to … MicroRNAs and sexual orientation
Prehistoric genomes reveal the genetic foundation and cost of horse domestication Reported as: Reshaping the horse through millennia Excerpt: “Domestication is generally associated with repeated demographic crashes. Yet, mutations that negatively impact genes are not eliminated by selection and can even increase in frequency when populations are small. Domestication thus generally comes at a cost, as … Removing natural selection; reshaping the horse; adjusting evolutionary theory
without human pheromones we would not survive long enough to develop genetically predisposed hormonally controlled preferences for the visual appeal of other people
A detailed model exemplifies the effects of olfactory/pheromonal conditioning, which alters genetically predisposed, nutrient chemical-dependent, hormone-driven mammalian behavior and choices for pheromones that control reproduction via their effects on luteinizing hormone.
It is no fun to be ignored, but that seems to be a common problem for those who challenge theories, whether or not those theories make sense in the context of biological facts.
We incorporated what is currently known about the ability of chemical signals to condition behavior. This conditioning occurs via epigenetic effects that calibrate and standardize the molecular biology of intracellular signal transduction and stochastic gene expression
Earlier this year I addressed the commonalities and the adaptive evolution of differences in systems-level and behavioral responses in the context of the FDA Critical Path Initiative and ASAM policy statement.
The link to appetite regulation is from olfactory (and probably pheromonal) stimuli directly to the diet-responsive (and probably pheromone-responsive) hypothalamic neurogenic niche that controls nutrient chemical acquisition via its control of the dopaminergic and serotoninergic neuronal systems
Learning associated with brain function is learning that is dependent on a direct link from sensory cues to brain function.
Their results exemplify how olfactory/pheromonal conditioning of responses paired with with other sensory input occurs.
