# Neural Plasticity **Domain:** Neuroscience / Learning **Doc Type:** Scientific Concept Node **Maturity:** Established **Related:** [[Synaptic Ensemble]], [[Long-Term Memory Substrate]], [[Phosphorylation Signaling]] --- ## Definition **Neural plasticity** is the capacity of neural systems to change their connectivity, synaptic efficacy, intrinsic excitability, molecular state, or functional organization in response to activity, experience, injury, or development. ## Continuity relevance Identity persists through change rather than despite it. A continuity architecture must represent plastic state and history without assuming that fidelity means freezing the brain at one configuration.
