Only 6 months later, the listening and speaking regions of the infant brain are active at the same time. This is just around the time babies are learning to babble. But the babies aren’t actually babbling while they are in the MEG. They are just listening silently to language sounds. It is as if the infant brain is practicing, trying to figure out how to produce all the sounds it hears everyday. This pattern of brain activity suggests that the speaking and listening parts of the infant brain are beginning to work together. Over the past six months, connections between these two brain regions have grown. The connections have strengthened as the babies listened to language.
