New Insights into the Neural Mechanisms Underlying Infant Attachment

Specific neurons in the brain's zona incerta (ZI) play a crucial role in the early social interactions of an infant and its mother, building their bond and reducing stress, according to a new study in mice. Activation of the same neurons in adult mice increased anxiety- and fear-like responses, the study showed.
