“Is that dopamine on your leg or are you just… happy?”
The owner of the geeky chemistry tattoo, Chelsey, explains:
This tattoo is of two very important molecules in your body: dopamine and serotonin. Dopamine is on the top and serotonin is on the bottom. Dopamine is mostly in your brain and when it is increased, it makes you happy. Serotonin also makes you happy but is found mostly in your gut. I like this tattoo because it perfect portrays a cross between hard science and philosophy (hence the combatting molecules of mind and body, comparing that with Descartes’ mind/body dualism). I am a psychology major with a minor in biology and chemistry.
