Developmental plasticity refers to changes in neural connections during growth, influenced by environmental interactions and learning. Similar to brain plasticity, it specifically involves how neurons and synapses adapt during development. Most of these connections form from birth to early childhood, following three main processes, with critical periods determining lasting changes. The term can also describe how an embryo or larva adjusts its traits based on the environment. Unlike phenotypic plasticity, which can be reversible in adulthood, developmental plasticity shapes traits early in life that usually remain permanent.
