Lack of a gender detection region for face stimuli

Full text available for free: The gender of face stimuli is represented in multiple regions in the human brain Alumit Ishai, Christian Kaul, Geraint Rees Published on 21 January 2011

Excerpt:
“Given the evolutionary importance of gender information and its fundamental nature in face processing, it is plausible that there is no “gender-detection region” in the human brain, but rather, gender information is a distributed attribute.”

The lack of a “gender-detection region” is a telling feature of how gender perception works in other animals and in humans, because no neurophysiological mechanism has been proposed that enables the differences in perception of male and female faces. In other animals, the perception of males and females is associated with olfactory/pheromonal input rather than consciously perceived visual input.

If, as it appears to be, gender information is a distributed attribute, it seems more likely to be steroid hormone-dependent due to the effects of differences in steroid hormones on the brain structures where information must be integrated in gender detection. Olfactory/pheromonal stimuli have effects on levels of steroid hormones that cause sex differences in these brain structures. Given existing animal models, gender perception is more likely to result from associations between the effects of olfactory/pheromonal stimuli on the development of hormone-dependent brain structures than it is to result directly from visual input. One reason for the focus on olfactory/pheromonal input is because there is no neurophysiological mechanism that allows visual input to elicit the effects that are frequently, if not always, attributed to visual input. Another reason, is because we do not typically attribute to visual input the development of food preferences, which we seem to somehow know are dependent on olfactory stimuli.

In my olfactory/pheromonal model, sexual preferences are like food preferences that develop under the influence of what might be metaphorically termed “the mind’s eyes.”  The mind’s eyes consist of a distributed neuronal network that collectively integrates responses to olfactory and visual input. Studies of non-human mammals indicate that visual input has relatively little impact on the development of sexual preferences.

Mmy model focuses on olfactory input.  It incorporates well-conserved molecular biochemical networks of the metabolic, signaling, and regulatory types, which are essential to the development of behavior in all organisms. This behavior included the identification of conspecifics and the development of sexual preferences.  My  model also provides a detailed gene–cell–tissue–organ–organ system pathway from sexually dimorphic hormone-associated olfactory input and from MHC/HLA-associated olfactory input to sexually dimorphic behavior.

Obviously, there is more to human pheromones than meets the eyes.

James Kohl owns Pheromones.com, and he has published books and award-winning research journal articles about human pheromones. With colleagues he was the first to show that a mixture of human pheromones increases the flirtatious behaviors of women, and increases their level of attraction to the man wearing the mixture - during a real-life social circumstance lasting 15 minutes.

What is the vomeronasal organ (VNO)?

The vomeronasal organ (VNO) is a cone-shaped organ in the nasal cavity, which is believed to be one of the body's receptors of pheromones. More, specifically, the VNO, which is part of the accessory olfactory system in the nose, does not respond to normal scents, but may detect odorless, barely perceptible pheromones.

Other schools of thought believe that it is not the VNO but rather cells in our main olfactory system and their affects on hormones secreted by the hypothalamus that are responsible for the affects of pheromones.

What are optimized pheromones?

Optimized pheromones are lab-certified pheromone formulations that have the optimum concentration of biologically active pheromones scientifically proven to produce behavior-altering results -- particularly as sexual attractants. Optimized pheromone formulations do not necessarily contain the maximum level of pheromones available on the market, but rather contain the greatest degree (and combination)of human pheromones that trigger a conditioned biological response in humans that, in turn, dictate their sexual behavior. Optimized pheromones also release neurotransmitters that directly modify the behavior of the opposite sex, such as triggering sexual excitement. For example:

Optimized pheromones for men are scientifically proven to bring about an increase in the luteinizing hormone (LH) in women, thereby causing a woman to have a heightened sexual responsiveness to a man. This LH surge elevates a woman's predisposition towards sexual activity.

Optimized pheromones for women are scientifically proven to bring about a biochemical surge in men, thereby causing a man to have a heightened sexual responsiveness to a woman. This biochemical surge is what makes a man fiercely determined to copulate.
