Popular YouTube channel AsapSCIENCE has produced a great new video explaining how your brain works differently when you are in love — just in time for Valentine’s Day.

Surprisingly (or maybe not, depending on how deeply you’ve felt love), a brain in love looks a lot like a brain on cocaine.

“Cocaine acts on the pleasure centers in the brain by lowering the threshold at which they fire,” the video’s narrator says. “This means you feel really good a lot easier. We see the same thing in the brains of those in love. But it’s not just the cocaine or the love that makes you feel good, it’s the fact that anything you experience will now more easily set off pleasure centers and make you feel good.”
