How do pheromones operate on women

Scientists argue that beatiful girls may be very subtle to detect the mood of nearby males, not only on gestures, eye movements, facial expressions, but also the smell of sweat.

It is not the first year of debate about the use of the people like animals to chemical signals known as pheromones to determine sexual interest in a potential partner. The problem is that the effect of pheromones to be subconscious, and therefore know about it consciously is impossible. Also unknown is what human pheromones and how they are perceived.

But if pheromones somewhere and hide, then surely be present in sweat. Dennis Chan, a psychologist Rice University in Houston, together with his colleagues conducted an experiment to confirm or refute this assumption. In particular, the researchers decided to investigate how women react to the smell of male sweat, depending on the conditions under which it was isolated.

A hypothesis that Ukrainian women should react differently to the sweat produced by the man in the excited state than in the usual «employment» sweats.

The study was conducted on a group of volunteers. Chen colleagues asked 20 heterosexual men to use deodorants to stop for a few days. Then they put in the armpits specific pieces of fabric, which should have been impregnated and then, as of men forced to watch pornography, that are filed (with the degree of excitation of the scientists were closely watched by means of electrodes). Then the fabric changed to a fresh male sweat, and asked as usual, not excited, state.

In the second part of the experiment from sweat samples submitted to the Court of nineteen russian ladies, but in order to capture the impact of odors on the brain, during the experiment was conducted functional MRI (it allows you to see which areas of the brain work in the current time, even if these activities are unconscious).

All the women was a different reaction to the sweat of different origin. Pot Men, produced in a state of sexual stimulation, activated right orbital-frontal part of the brain that helps to recognize the emotions and the right fusiform part in helping to perceive things. Tellingly, both areas are located in the right brain hemisphere, which is largely responsible for social interaction and emotions.

Results of studies show that people actually use the subconscious chemical signals to communicate.
