Core Concept: How synaptic pruning shapes neural wiring during development and, possibly, in disease [Neuroscience]

At birth, an infant’s brain is packed with roughly 100 billion neurons—some 15% more than it will have as an adult. As we learn and grow, our experiences strengthen the circuits that prove most relevant while the others weaken and fade. Nerve cells in the cerebellum called purkinje cells (blue)...
