Songbirds seem to enjoy singing. And while a great deal of research has investigated the development and production of birdsong, little is known about the motivation to sing.
New work out of Lauren Riters’ lab at the University of Wisconsin-Madison teases out the relationship between singing, reward, and endogenous opioids in songbirds. The results suggest that studying songbirds can teach us about the shared neurobiological mechanisms underlying social reward in all vertebrates, humans included.
