Certainly, the reproductive behavior of the dominant animal in any mammalian hierarchy is under constant scrutiny by those on its lower rungs. Surely something atavistic is at work. From our demand for waterproof cosmetics to our sense of a rightful place in the cosmos, we are shaped by the biology of sex far more than we would like to admit. Indeed, the debate over biologically based gender differences has caused no end of cultural and political conflicts as, spurred by changing economic conditions and the technological innovations of birth control, we seek the social equilibrium of a new sexual norm. Yet when we look at ourselves in the mirror of biology, we see that of all the works of nature, human sexuality is perhaps the strangest.

Whether you remember it or not, you dream every night. While experts are still divided on what our dreams mean, research has given us some very eye-opening information about dreams. Our most vivid dreams happen during rapid eye movement REM sleep , which happens in short episodes throughout the night about 90 to minutes apart. Most of your muscles become paralyzed during REM sleep to prevent you from acting out your dreams.
Sex is a fundamental pleasure, and crucial to the survival of our species. Though not many people would disagree with the proposition that sexual behaviour depends on the brain, the neuroscientific study of human sex is still relatively taboo and much remains to be discovered. On the contrary, excellent experimental animal models mostly rat are available that have uncovered major behavioural, neurochemical, and neuroanatomical characteristics of sexual behaviour. Restructuring sexual behaviour into broader terms reflecting behavioural states wanting, liking, and inhibition facilitates species comparison, revealing many similarities between animal and human sexual pleasure cycles, some of which can serve as potential avenues of new human sex research. In particular, behavioural and brain evidence clearly shows that motivational and consummatory phases are fundamentally distinct, and that genitally-induced sexual reward is a major factor in sexual learning mechanisms.
