The development of neural networks through …
- neural pruning
is both genetic and subject to environmental influences
Neural networks can change developmentally;
- over time
- after injury
Brilliant clip of the wonderful Marian Diamond talking about ageing, brains, neuroplasticity and rats: https://www.youtube.com/watch?v=0APJD-wN7MA
Amazing clip of a new synapse forming: https://www.youtube.com/watch?v=9ebifjoFtJs credited to the amazing neuroscientist Dr. Lila Landowski.

Using Draganki to support neuroplasticity: using a study to support a concept or theory
If you wish to use Maguire for this section, you could consider evaluating with this study: https://digest.bps.org.uk/2019/02/21/young-adults-with-better-navigation-skills-do-not-have-larger-hippocampi-raising-questions-about-the-meaning-of-the-famous-taxi-driver-studies/
Linking neuroplasticity to Abnormal Option (biological etiology of MDD): https://www.hindawi.com/journals/np/2017/6871089/
Linking neuroplasticity to the Health Option (e.g. stress): you could look at research that demonstrates the neuroplastic effects of mindfulness, such as Holzel et al. (2011).
Practice Questions and Model Answers
Please be aware from 2020 SAQs can include the terms neurons, neural networks and neural pruning.
- Describe one study of neuroplasticity. (9)
- Explain how neural networks are formed with reference to one research study. (9)
- Explain the process of neural pruning with reference to one research study. (9)
- You could include dendritic retraction and the study of Draganski’s jugglers where the mid temporal region decreases in size three months after the juggling group ceased practising.
