Why Are Girls Better Listeners? 1) Because They Rule and 2) Because They Have More Estrogen

That's right, a recent study has proven that estrogen plays a key role in the ability to hear and process sounds. According to the article:

a postdoctoral fellow in Pinaud's laboratory, demonstrated that increasing estrogen levels in brain regions that process auditory information caused heightened sensitivity of sound-processing neurons, which encoded more complex and subtle features of the sound stimulus. Perhaps more surprising, says Pinaud, is that by blocking either the actions of estrogen directly, or preventing brain cells from producing estrogen within auditory centers, the signaling that is necessary for the brain to process sounds essentially shuts down. Pinaud's team also shows that estrogen is required to activate genes that instruct the brain to lay down memories of those sounds.

And that's not all they think it can do. They are conducting further research to see if it controls even more of the body's functions. Thus proving that the more estrogen you have, the awesomer (it's a real word) you are and it's yet another reason why girls rule more than guys.. at everything.
