“To avoid the influence of taste or preference cues on brain activity, they infused glucose, lipids (fats), and water (as a control) directly into the participants' stomachs. Then they measured the participants' brain activities and dopamine release in the striatum, an area involved in reward and motivation.”

“Cold and intense exercise also engage catecholamines, which gives the idea a biological component beyond willpower alone. In a controlled human immersion study, cold water produced large increases in plasma norepinephrine and dopamine, although the exposure was much longer than a brief cold plunge.”

“It typically manifests later in life and is caused by the destruction of neurons that produce dopamine. A growing body of evidence points to exercise's ability to reduce the risk of developing Parkinson's disease.”

“Early mechanistic evidence is intriguing. In a small positron-emission tomography study, yoga nidra meditation increased endogenous dopamine release in the ventral striatum and increased theta activity.”

“Specifically, vitamin C serves as a cofactor in the regulation of neurotransmitters by preventing excess dopamine accumulation in neurons that generate reactive oxygen species. In vitro studies suggest that vitamin C might also aid in the formation of neural circuits.”

“Caffeinated and decaffeinated coffee share many polyphenols, but caffeine adds alertness and blocks adenosine receptors involved in sleep pressure and dopamine signaling. In this clip, Dr. Rhonda Patrick and Derek from More Plates More Dates discuss why that difference may matter for brain health.”

“The study was cross-sectional and included 22 lean adults, so it cannot show that sugar caused the brain response, reduced dopamine-receptor density, or produced an addiction. Animal studies support stronger mechanistic claims, but they should not be used to equate sugar with cocaine, methamphetamine, or nicotine in humans.”

“01:05:23 - The omega-3 fatty acid DHA increases dopamine in the frontal lobe of the brain in schizophrenics. Study. 01:23:10 - Mice without IGF-1 receptor have extended lifespan and greater resistance to oxidative stress.”

“Parkinson's disease is a progressive neurodegenerative disorder with no cure. The disease, which typically manifests later in life, is caused by the destruction of neurons that produce dopamine — a neurotransmitter best known for its role in motor, motivation, and pleasure control.”

“While on the placebo treatment, participants’ willingness to expend cognitive effort increased as their baseline dopamine synthesis capacity increased. Notably, while performance on the working memory task decreased with difficulty, there was no relationship between task performance and dopamine levels.”
