How a mother’s voice shapes her baby’s developing brain

But what actually happened when these older children heard their mother’s voice?  … But what the scientists found was even more remarkable. A mother’s voice activated a wide range of brain structures including the amygdala, which regulates emotion, the nucleus accumbens and medial prefrontal cortex, which are part of a major reward circuit, and the fusiform face area, which processes visual face information. This pattern of brain activity can be likened to a neural fingerprint, where a mother’s voice triggers specific activity in her child’s brain.
