Dopamine
A key neurotransmitter in the central nervous system involved in the regulation of reward, motivation and pleasure. Changes in its baseline levels are associated with shifts in dietary preference.
Timeline (last 90 days)
Dopamine is not what is commonly called the 'happiness molecule,' but a neurotransmitter that signals anticipated reward.
The dopamine system is most sensitive to the difference (prediction error) between expected and actual rewards, with dopamine release enhanced when independently solving a difficult problem yields an unexpectedly large reward.
The release of dopamine produces feelings of pleasure and even chills when hearing the right music, sharing the same neural circuitry as survival rewards such as food and sex
Frisson is thought to be the brain's intense reward response to "resolution following violated expectation" in music, where dopamine is suddenly released and triggers a skin response when a melody develops in a surprising yet perfectly fitting way
Dopamine release is strongest across the complete chain of anticipation → effort → reward.
Cyclical fluctuations in estrogen levels affect the metabolism of dopamine and norepinephrine, causing ADHD symptoms in women to often worsen significantly around the menstrual cycle, puberty, and perimenopause.
Research in the European Journal of Physiology showed that the dopamine increase from cold exposure is close to double and can last for several hours.
Acetylcholine, adrenaline, and dopamine work synergistically to allow a person to enter and maintain a state of precise focus.
The dopaminergic system encodes reward prediction error—the difference between the reward actually received and the expected reward—a mechanism that is the biological counterpart of the temporal difference (TD) reinforcement learning algorithm.
