The big idea: The brain is not fixed — it changes. Neuroplasticity is the brain's ability to reshape itself, growing and strengthening connections as we learn and experience new things.
Neuroplasticity happens throughout life. Every time you practise something, the connections between nerve cells across the synapse can grow stronger.
The brain also does the opposite. Connections you rarely use are slowly removed — this is called pruning. In short: use it or lose it.
Memory hook: Use it, grow it; skip it, prune it. Experience strengthens the connections you use and removes the ones you don't.

Two everyday examples: Neuroplasticity shows up in two clear ways: when we learn a new skill, and when the brain recovers after damage.
How neuroplasticity works
Learning strengthens
Practising a skill fires the same connections again and again, so they grow stronger and faster — this is synaptic strengthening.
Recovery reroutes
After injury, healthy areas can slowly take over some jobs of a damaged area, helping a person regain lost abilities over time.
Practise → strengthen · Damage → reroute
Let us walk through one clear example. Imagine a student who practises juggling for a few minutes every day for a month.
Imagine you are there: At first the balls drop constantly. But with daily practice, the movements slowly feel automatic. Inside the brain, the connections controlling those movements have grown and strengthened. The skill is now 'wired in' — a real, physical change from experience.
The same idea explains recovery. After a stroke damages one area, careful therapy can help other parts of the brain take over, so some lost movement or speech slowly returns.
Exam tip: Name the change (connections grow/strengthen or reroute) and link it to one behaviour — learning a skill or recovering after injury both work well.

The concept behind it: Neuroplasticity is a powerful example of the concept of change — it shows that behaviour and the brain change together through experience, rather than being fixed for life.
Studies are just examples: You do not need to memorise a named study. You can explain neuroplasticity with a real example (like learning to drive or recovering after injury) or a made-up one — both score full marks — as long as the change is clear.
Strengths of the idea
- Brain imaging can show real, physical changes after practice
- It explains learning, memory and recovery in one idea
- It brings hope — the brain can improve and heal, not just decline
- It has real uses in rehabilitation after brain injury
Limits of the idea
- Plasticity slows with age, so change is not equally easy for everyone
- It is hard to be sure practice alone caused the brain change
- Not all change is good — some rewiring can strengthen unhelpful habits
- Brain imaging shows a change, not exactly why it happened
How to reach the top marks: The best answers evaluate: weigh a strength (imaging shows real change; helps recovery) against a limit (age; hard to prove practice alone caused it), then reach a short judgement.
How Paper 1 tests this: Neuroplasticity is biological-approach content. On Paper 1 this term is tested in two ways.
Two ways it is tested
- A short-answer question [4 marks]: describe or explain it with one example.
- An applied question [6 marks]: use it to explain a situation in a given context.
The [15] essays: The big [15] essays are concept-framed and come in the four contexts. This term can support one: for example, the concept of change in the health and well-being context.
A student practises juggling for a few minutes every day and gets much better over a month. Explain how neuroplasticity could account for this improvement, and one limitation of concluding that practice alone changed their brain.
Model answer plan
See the answer broken into clear points, with guidance on how each point earns marks.
Common mistakes: 1. Describing, not applying. In the applied [6], explain THIS student, not plasticity in general.
2. No physical change. Say what actually changes — connections grow/strengthen.
3. Assuming practice is the only cause. Other life changes could contribute.
4. Forgetting the concept. Tie back to change.
