Safely tucked away within your skull is one of the most remarkable, complex organs in your body – your brain! Although there is much we are yet to discover about the brain, scientists have revealed an interesting ability of the brain that can change the way we behave and learn. Previously it was once thought our neural pathways and processes were fixed and unchangeable, but scientists now know these neural pathways can respond and adapt to experience and needs (1). This exciting phenomenon of a changeable brain is known as neuroplasticity and it is incredible.
FANTASTIC NEUROPLASTIC
I can change my mind, so what?
Our brain is responsible to innervate physical movement and govern conscious thought, but it is also responsible for innumerable unconscious cognitive processes including memory, perception, language and learning (2). This knowledge combined with the discovery of neuroplasticity has led to an ‘explosion of interest in the power of brain training to improve our focus, memory, attention and performance‘ (3).
Brain training?
Imagine you have commenced learning the piano, you are slow and clumsy. After consistent practice over a couple of days, your improvement is apparent. All those neurons that had to fire repeatedly in your brain have practiced, too. Each time they’ve fired, the stronger the connection has become. As you become more proficient with practice, the more distant neurons become ‘rich, well-organised neural networks’ (4). After a few years, if we were to study in your brain, your cortical “map” would have changed and your brain would reflect improvements in dexterity and auditory processing and spatial, verbal and mathematical performance. It would also make your brain more resistant to age-related degeneration (5).
I don’t want to learn the piano, how else could I benefit?
Every moment we are learning, we create opportunity for the brain to stabilise and reinforce new skills. However, the benefits of neuroplasticity are not just limited to new skills. Each time your brain strengthens a connection to advance your mastery of a skill, it weakens other neuronal connections that weren’t used at that precise moment – this is a negative plastic change.
Oh no! What if my brain weakens important neuronal connections?
While the negative plastic change suppresses “noise” (irrelevant, interfering activity in the brain), brain plasticity is a two-way street; it is just as easy to generate negative changes as it is positive ones. For instance, a child that constantly tilts their head to the left when reading is changing the neuronal densities in their visual pathways and processing. By not using both eyes effectively, they are contributing to eye strain and physiological vision problems, inefficient visual processing and, consequentially, impeding their learning and academic performance.
Funny you say that, while my child doesn’t do that exactly I have noticed them…
At Smart Vision Optometry, vision, visual information processing and neuroplasticity are deeply embedded within the kind of work we do. Our patients learn new skills to create vision and visual information processing proficiencies and practice activities to disrupt any negative changes that they have reinforced. We work with people and their brains – and neuroplasticity is the foundation of a lot of our work. Lots of our patients are children, because how they use their brain and their neural processing is critical. Achieving mastery of relevant skills can contribute to effective learning and academic performance at a formative time during their formal education.
Sounds serious.
It absolutely is! But it doesn’t mean it can’t be fun. If you’re in one of the waiting rooms of our practice you’ll only hear laughter. You may even get a glimpse of balloons or a therapist and a child crawling around like spiders on the floor, encouraging bilateral integration and building a fun foundation for higher order processing.
