Burst activation of dopamine neurons produces prolonged post-burst availability of actively released dopamine For years now, scientists have noticed a rather strange phenomenon in animal models: scientists would stimulate dopamine production in the brain, but once the stimulation was over, the dopamine would remain. Bita Moghaddam is chair and professor of behavioral neuroscience at Oregon Health and Science University. She says that when dopamine is released, dopamine transporters take the dopamine back up into cells so it can be synthesized and broken down. So scientists had assumed that the dopamine that remained for those twenty minutes was just leftover dopamine from the original activation. But in theory the dopamine transporters should be more efficient in taking up the dopamine. Article link: https://www.nature.com/articles/s41386-018-0088-7
