Vision happens when patterns of light entering the eye are converted into reliable patterns of brain activity. This reliability allows the brain to recognize the same object each time it is seen. Our brains, however, are not born with this ability; instead, we develop it through visual experience. Collaborating scientists at MPFI and the Frankfurt Institute for Advanced Studies have recently discovered key circuit changes that lead to the maturation of reliable brain activity patterns. Their findings, published in Neuron this week, are likely generalizable beyond vision, providing a framework to understand the brain’s unique ability to adapt and learn quickly during the earliest stages of development.
