Introvert, Extrovert, Ambivert & Omnivert

Nope, it is not a figment of your imagination! Your friend, son, daughter, parent, colleague and you on occasions, display different behaviours and preferences, and do you know what, it's ok and phenomenally brilliant.


A major difference between the reactions within the brains of introverts and extroverts is the way the individual responds to the neurotransmitter dopamine. Dopamine is a chemical released in the brain. It provides the motivation to seek external rewards like earning money, improving social status, attracting a sexual partner, or being chosen for a high-profile project at work. When dopamine floods the brain, both introverts and extroverts become more talkative, alert to their surroundings, and motivated to take risks and explore their environment.

It’s not that extroverts have more dopamine present in their brains than introverts do. In fact, they have the same amount of dopamine available. The difference is in the response to the dopamine reward network.
