Pheromones, GnRH and social neuroscience

ordon Research Conference, 18-23 August 2013, West Dover, VT

Neuroethology: Behavior, Evolution & Neurobiology
Networks, Circuits, and Modules

Excerpt: “The sixth Neuroethology GRC will be taking place at a time when classical neuroethological topics on sensory and motor systems are increasingly integrated with molecular and genomic approaches, social neuroscience, computational neurobiology, and robotics.”


The final conference presentation is at 8:30 pm – 9:05 pm by Yoshitaka Oka (University of Tokyo) “GnRH neurons involved in central regulation of reproduction and reproductive behavior”

My comment: Why did they save for last the only conference presentation that links the nutrient-dependent pheromone-controlled adaptive evolution of microbes to man? This might delay the opportunity for others to interpret their findings in the context of glucose uptake-regulation and pheromone-regulation of the GnRH neuronal system in mammals. Others might also then miss the opportunity to link adaptively evolved hormone-organized and hormone-activated behaviors in invertebrates to vertebrates (e.g., via the honeybee model organism).

Do the conference organizers not realize that the “…central regulation of reproduction and reproductive behavior” is nutrient-dependent and pheromone-controlled? Perhaps they simply hope to provide a surprise ending. If so, I hope I haven’t spoiled the surprise, but I think it’s an ending that should have been considered at the beginning of any study design, since GnRH is conserved and its receptor is diversified across 400 million years of vertebrate evolution, which means it can also be linked to the adaptive evolution of species from microbes to man via olfaction and odor receptors.

See for example:
Neurobiological mechanisms underlying GnRH pulse generation by the hypothalamus
Innate versus learned odour processing in the mouse olfactory bulb
