Shortly after birth, human brains expand rapidly with the experience of an entirely new world. During this period, neurons in the newborn brain compete with one another to form lasting connections, called synapses.
Non-neuronal cells called astrocytes (red) churn out hevin (green), a protein crucial for the refinement of neuronal connections in the developing brain.
