I agree, Ron. My cross-species comparisons are of the mammalian 
neuroendocrinological type. Simply put, mammalian pheromones appear to 
activate gene expression in neurosecretory tissue of the brain, the most 
important organ of any organ system involved in behavior. More simply 
put, pheromones are the only social-environmental sensory stimuli known 
to activate the following pathway: gene-cell-tissue-organ-organ system, 
which is linked to behavior.

My comments on estradiol content in the amygdala and cross-species 
comparisons were intended to give credence to the role of the amygdala in 
olfactory signal transduction. This role may be extremely important to 
mammalian, including human, 
olfactory-genetic-neuronal-hormonal-behavioral reciprocity.

Perhaps human pheromones elicit the "right" occilations that in turn 
elicit changes in gondatropin-releasing hormone pulsatility (the 
biological core of mammalian reproduction). If so, we may one day be able 
to merge our concepts into a cohesive explanation of a link between the 
genetic nature and the social-environmental nurture of human behavior.
