“Then they examined whether the mice preferred only sucrose-containing solutions or a high-fat diet after being food deprived. Finally, they administered a dopamine-inhibiting drug to the mice to determine if dopamine signaling influenced the mice's eating behaviors.”

“When social drinkers (people without an alcohol use disorder) first consume alcohol, there’s an activity spike in parts of the brain called the ventral striatum and the nucleus accumbens — both of which are key components of the brain’s reward system. Alcohol triggers dopamine release in these areas, contributing to feelings of pleasure and satisfaction and encouraging repeated behavior.”

“An 8-week exercise intervention that included cycling and walking increased blood flow to brain regions involved in motor control and reward processes and improved dopamine-related brain function in overweight and obese individuals.”

“But FGF21 is also produced in working muscles. Research shows that FGF21 can cross the blood-brain barrier and bind to receptors in the hypothalamus. It also alters dopamine signaling – a key process in the brain's reward pathways and alcohol-seeking behavior.”

“Beneficial activities like exercise and hard work also boost dopamine levels but without the massive peaks associated with cocaine use. Learn more in this clip featuring Dr. Andrew Huberman. Read full publication.”

“Once in the brain, it caused the loss of dopamine neurons in animals.”

“Hour-long exposure to neck-deep cold water (57°F, 14°C) increased norepinephrine by 530 percent and dopamine by 250 percent. But a 20-second whole-body dip in very cold water (40°F, 4.4°C) increased norepinephrine 200 to 300 percent.”

“Cannabis use may disrupt the delicate balance of brain chemicals like dopamine, a neurotransmitter critical for attention and motivation. Learn how to improve attention by leveraging the effects of dopamine in this episode featuring Dr. Andrew Huberman.”

“Microbes in your gut may trigger your motivation to exercise, a new study in mice has found. Compounds produced by the microbes signal the release of dopamine – a neurotransmitter produced in the brain that promotes the "runner's high" and the desire to exercise.”

“A staggering 60% of all calories Americans consume come from ultra-processed foods that fail to induce proper satiety, remain cheaper than whole foods, and hijack our dopamine reward pathways, pushing us to overeat, incentivizing unhealthy food choices, and reinforcing addictive eating behaviors.”
