The Unsexy Truth About Dopamine
If there were a celebrity among brain chemicals, it would be dopamine. Supposedly released whenever we experience something pleasurable, it’s forever linked to salacious stories of sex, drugs and wild partying in the popular press. The Kim Kardashian of neurotransmitters, it gives instant appeal to listless reporting and gives editors an excuse to drop some booty on the science pages.
There are too many bad examples to mention in detail, but I have some favourites. The Sun declared that “cupcakes could be as addictive as cocaine” because they apparently cause “a surge of the reward chemical dopamine to hit the decision-making area of the brain”. The article was topped off with a picture of Katy Perry, apparently a “cupcake fan” and, presumably, dangerously close to spiralling into a life of frosted-sponge addiction.
