What is Dopamine?
/ˈdəʊpəmiːn/
Dopamine is a neurotransmitter — a chemical messenger in the brain — that plays a central role in motivation, reward-seeking, and the anticipation of pleasure rather than pleasure itself.

Everyday Example
The buzz of excitement you feel when your phone lights up with a notification — before you even know what it says — is dopamine in action. It is the anticipation, not the reward.
publicReal-World Application
“Social media platforms are deliberately designed to trigger dopamine responses through unpredictable notifications and likes — the same mechanism that makes slot machines addictive.”

Did you know?
Dopamine was discovered in the late 1950s by Arvid Carlsson, whose research into its role in Parkinson's disease eventually won him the Nobel Prize in 2000.

Key Insight
Dopamine is not the "pleasure chemical" — that is a common misunderstanding. It is the "wanting" chemical. It drives you to seek rewards but does not deliver satisfaction when you get them.
