Published in the Journal of Neuroscience, the finding that dopamine drives plasticity in the auditory pallium of zebra finches lays new groundwork for advancing the understanding of the functions of this neurotransmitter in an area of the brain that encodes complex stimuli.
“People associate dopamine with reward and pleasure,” says lead author Matheus Macedo-Lima, who performed the research in the lab of senior author Luke Remage-Healey as a Ph.D. student in UMass Amherst’s Neuroscience and Behavior graduate program. “It’s a very well-known concept that dopamine is involved in learning. But the knowledge about dopamine in areas related to sensory processing in the brain is limited. We wanted to understand whether dopamine was pl ....
