Excerpt: “Hedione exhibited significantly enhanced activation in limbic areas (amygdala, hippocampus) and elicited a sex-differentiated response in a hypothalamic region that is associated with hormonal release.”
Excerpt: “The question if humans can communicate via pheromones in the same way as animals is under debate.”
My comment: There is no debate among serious scientists who understand the fact that epigenetic effects on cell type differentiation are nutrient-dependent, RNA-mediated, and pheromone-controlled in species from microbes to man. That fact has been detailed in the following series of published works.

When he was wearing the mixture compared to when he wore the diluent, women were more likely to make eye contact (t (12) = 3.43, p = 0.01; IRR: r = 0.964, p = 0.01). They also laughed more (t (12) = 5.20, p < 0.01; IRR: r = 0.810, p = 0.01), and they subsequently rated themselves as being more attracted to him (t (12) = 2.786, p = 0.016).Our results combine the known effects of androstenol on LH and on mood with a likely behavioral affect of androsterone.
