Woman smelling that men turn

To tell whether a man is not on your "thoughts" and not too difficult.

His eyes, he walks, he sexy smile, clearly showed that he is thinking about that.

Not only that, the most recent research has also shown that a woman can also distinguish the men's sweat taste, at least in the subconscious can.

Humanity is not like the animal has a feature called pheromones chemical substance, and brought it to the specific expression of their sexual orientation? scientists on this issue for many years.

The problem is that scholars generally believe that the role of the pheromone is subconscious — this means that even if we really use it, we do not know. Another problem also difficult: we do not know this information in what is possible, does not know how to perceive it, so the researchers on it poorly.

However, if people really have pheromones, which should be in the Khan, right? Dennis · Chen, Rice University in Houston, a psychologist and her team to design an experiment to compare the female on the different cases of male sweat responses — men in calm conditions and excited state nasty sweat.

Researchers to infer that if man really produces and perception pheromones, the woman should be can't man full of lust for Khan and normal Khan made different reactions.

Chen and her team found a 20-bit heterosexual man and ask them to stop using a deodorant and scented daily supplies for a period of time.

Then, the small pad placed in their armpits, let them watch A movie and excited (the researchers attached to them, the image indicates that the electrode they really excited). After the men were replaced with new cushions, collect them in the everyday State secretion of sweat.

Researchers recruited 19 brave woman, let them sniff those men sweat stained mattress, and scan their brains.

The researchers used functional magnetic resonance imaging (fMRI), this technology is able to show people who are using brain region — even if it is subconscious brain activity.

There is no doubt that women's brain for the smell of sweat to make an entirely different reaction (Oh no, not one of them was smoked down).

Full of desire Khan will stimulate the right amount of cortical osteotomies and right spindle cortex, but normal sweating does. Both regions respectively, to help us identify emotional and cognitive things that are in charge of Olfaction, social and emotional right hemisphere.

This discovery has supported research in Chan pointed out that human use of subconscious chemical signals to communicate that view.

This study was published in December 31 of the journal of neuroscience.

In other words, we may turn to show than we intend to show that much more straightforward.

Do you have for your colleagues think? she probably knew — at least subconsciously know.
