Definition
Neuroplasticity is the brain’s capacity to reorganise structure and function in response to sustained, salient experience — not only in childhood.
Origin
Human and animal studies show experience-dependent plasticity across sensory, motor, and cognitive domains — maps expand, compete, and renormalise with training load (Pascual-Leone et al., 2011). Popular case literature (The Brain That Changes Itself) synthesises rehabilitation and learning outcomes as physical circuit change, not metaphor.
Mechanism
| Principle | Plain language |
|---|---|
| Use / lose | Unused circuits yield territory to active ones |
| Competitive remapping | What you repeat wins cortical real estate |
| Hebbian co-activation | Firing together wires together (Hebbian learning) |
| Dose + salience | Insight alone is thin; months of directed reps move structure |
Plasticity has limits — age, injury, and load matter — but talent plateau is often a practice-design problem, not a fixed-brain verdict. Deliberate Practice and Learn to learn are operational layers on top of biology.
Applications
Treat stalled skill as rep design first: feedback, difficulty, error focus, duration — before identity verdict. Pair somatic and cognitive training when avoidance keeps maps frozen. Open Biology (MoC) when body state gates whether reps land.
