Immediate early gene activity in song control nuclei and brain areas regulating motivation relates positively to singing behavior during, but not outside of, a breeding context by Heimovics, Sarah A., Riters, Lauren V.

“…In some species, such as songbirds, much is known about how the brain regulates vocal learning, production, and perception. What remains a mystery is what…”
