Neurobiology: Sculpted by competition
Ole Petter Ottersen1
Abstract
Neuronal competition helps connections to form in the brain: the branches of less active neurons are more likely to retract — and, it now seems, less likely to grow — than those of their more active neighbours.
Competition pervades everyday life and sculpts our society. It is also an essential factor in the sculpting of our brains.
