Inside the complex tangle of biology and behavior that shapes our relationship with and experience of sex.

We’ve already explored the origins of sex, the neurochemistry of heartbreak, and how drugs affect desire. But what, exactly, happens in the brain when the body belts out its ultimate anthem of sexual triumph? Count on creative duo Mitchell Moffit and Gregory Brown, better known as AsapSCIENCE — who have previously explained how music enchants the brain and what science teaches us about curing hangovers — to break down the body’s response during orgasm:

But what about sexual experiences that don’t involve direct contact with a partner? What happens inside the brain then is arguably even more intriguing. In this talk from TEDxGlasgow, physiology teacher Gary Wilson peels the curtain on the complex scientific processes that accompany, and perpetuate, the world’s addiction to pornography. Specifically, he looks at how the Coolidge effect fuels internet porn:

For more on this ceaselessly fascinating tangle of biology and behavior, see the recently released The Chemistry Between Us: Love, Sex, and the Science of Attraction by neuroscientist Larry Young and journalist Brian Alexander, who take us inside the living brain to explore how its neurotransmitters, hormones, and circuits shape the very behaviors we find ourselves most invested in.
