Everyone knows that the brains of men operate differently than the brains of women. A man’s brain operates off of testosterone, and this seems to be a fundamental key in the wiring in the brain. Testosterone is exposed to a male from the time he is in his mother’s uterus, and then receives a big splurge of it during puberty. Removing some testosterone from a male is risking him of his manliness, but this isn’t so simple for some, especially mice.
A new study from Nature, claims that the brain pathway for sexual behavior in male mice are also present in the female mice. That suggests that their is potential for a female mouse to exhibit sexual male behavior. What makes it even more interesting is that these behaviors can be triggered by different smells. Like many other animals, mice uses pheromones to signal sexual behaviors, but what happens when you disables the part of the nose that receive these signals?
Males lacking the ability to smell pheromones seem to have trouble distinguish between male and female, mounting both genders while trying to mate. Also, males don’t fight other male mice when this function is turned off. Women on the other hand seem to display even stranger behavior. Women also have the trouble in distinguishing between the two genders and engages in the “pelvic thrusting” and “butt sniffing” which is a male behavior. Women also experience an alter in their maternal instincts by spending less time with their pups and being less protective over their nests.
This article was very interesting and should raise awareness of the complexity of the male and female brain. Could smells possibly cause weird mishaps in the human world? Can a man smelling perfume cause him to become more passive in his sexual behavior? If a woman smells cologne will she start trying to enact pelvic thrusts in her sexual behavior? Mix all of this with some crazy pheromones and you have one heck of a catastrophe! JUST HOW FAR APART ARE MARS AND VENUS ?
