There’s no shortage of blogs, podcasts, and self-help books on the importance of dopamine for the brain. In fact, many portray dopamine as the secret to better motivation, sharper thinking, and lasting happiness. So how much of this is based in science? What is the real role of dopamine in the brain, and is it really the key to better brain function?
Dopamine is a neurotransmitter—a tiny chemical molecule that carries signals throughout the brain. Outside the brain, it’s involved in blood pressure, digestion, kidney function, and more. Within the brain, dopamine is synthesized from an amino acid called tyrosine. Dopamine is produced in three parts of the brain: the substantia nigra, the ventral tegmental area, and the hypothalamus. Dopamine neurons located in the ventral tegmental area (VTA) interface with parts of our brain that regulate emotions and higher-level cognition. It is involved in aspects of brain function ranging from behavior to cognition to movement, motivation, sleep, memory, learning, and punishment and reward.
Dopamine is vital for healthy brain function. When issues arise in with dopamine balance in our brains, diseases and disorders can follow. Here are some of the most important functions of dopamine and evidence demonstrating the impact of dysfunction:
1. Dopamine is "good" or "bad." One of the most popular myths about dopamine concerns the idea that dopamine is either a good or a bad thing in our brains and bodies. The reality is that dopamine is a key molecule across a host of pathways, but too much or too little are both unhelpful. To this end, the idea that we should seek to massively boost dopamine levels or drop them dramatically is quite impractical and poorly backed by science. To this end, more dopamine doesn’t mean more happiness.
2. Dopamine is the “pleasure” molecule. Perhaps the most popular myth about dopamine relates to its reputation as the “pleasure molecule.” This misconception stems from older research that showed dopamine neurons activating in the context of reward, leading to the belief that dopamine was the reason we felt pleasure after engaging in a behavior like sex, drug use, gambling, or consuming certain foods. More recent research shows that dopamine has less to do with the experience of pleasure and more to do with anticipating or craving something. The technical term for dopamine’s role in reward circuits is “reward prediction error.” In essence, dopamine helps teach our brains when something is better or worse than predicted, so we can make better choices next time around.
3. You can “hack” “fast” or “detox” your brain's dopamine. Dopamine “hacking” or “fasting” have become popular concepts on wellness and productivity blogs. The basic idea is that we can easily harness our brain’s dopamine systems to make ourselves more successful, more focused, and generally better humans. Often, the concept is presented simply: By withdrawing from pleasurable activities and doing unpleasant things like taking cold showers, we can “reset” our brain’s dopamine, and in doing so reduce stress, hinder addictive tendencies, and generally improve our brain function. The issue is that there’s really no science to back the claim. The inventor of the “dopamine fast,” psychologist Cameron Sepah, has even indicated that the concept has less to do with actual brain dopamine, and more to do with a catchy framework for tackling unhealthy and impulsive behaviors.
At a very basic level, dopamine is an essential neurotransmitter that carries data between neurons. When dopamine neurons and systems are damaged, diseases like Parkinson’s can arise. While it’s less clear to what extent our actions directly impact brain dopamine levels, we know that we can positively impact the brain processes that are often discussed alongside dopamine. To this end, actions that can help enhance mood, focus, energy, and general brain well-being include:
