Newfound Brain Circuit Explains Why Infant Cries Prompt Milk Release
Led by researchers at NYU Grossman School of Medicine, the study explored a centuries-old observation in humans and other mammals that when a baby begins a feeding session, its cries alone can prompt its mother to release breast milk.

- This sensory hub then sends signals to oxytocin-releasing brain cells (neurons) in another region called the hypothalamus, a control center for hormone activity.
- In addition, the mothers' brain circuitry only responded to her pups' cries and not to computer-generated tones designed to mimic natural wails.
- Then, in a form of "reverse engineering," they traced how sound information travels through different areas of the brain to trigger milk flow.
