The study is published in PNAS. The babbling of zebra finches creates connections in the brain that enable them to memorize the song of their tutor. It was previously assumed that the initial babblings initiate the sensorimotor phase, the time at which the chicks begin to imitate the memorized song. This probably creates connections in the brain that enable the zebra finches to memorize and store the song in the first place. The content is provided for information purposes only.
