Understanding Neuroplasticity: How Our Brains Adapt, Heal and Thrive

Neuroplasticity is one of the most fascinating topics of psychology. It’s like a superpower that your brain possesses to change and adapt to your unique experiences. Our brain is very dynamic and we have thoughts consistently going on as we reflect upon things around us. Have you ever experienced you watched a movie or a series and stepped out with immense motivation or fear or started contemplating the purpose of life? Our thoughts are rapidly moving and our entire world changes, our perception of past, present and future.

Our brain creates new connections and resets itself frequently based on our interaction with the world. Recent studies tried to prove that neuroplasticity plays a vital role in a lot of things like recovery from a brain injury, and learning a new skill in mental health treatments. It’s been stated that mindfulness, cognitive training and physical exercise can improve neuroplasticity, making your brain function better and enhancing your overall well-being.

Importance of understanding neuroplasticity

Let’s learn about neuroplasticity in detail with the help of some examples.

1. Learning and skill development: Being aware of neuroplasticity allows us to improve our skills and abilities through practice and learning. For example, when you learn to play a guitar, your brain forms new connections and will strengthen the existing ones, helping you improve your skills.
2. Recovery from brain injury: It’s important to educate people about it as it may help in restoring the injuries in the brain. Healthcare professionals can use this knowledge to develop targeted therapies to heal patients from the injuries that affect their brain functioning.
3. Ageing and cognitive function: We are well aware that ageing affects our cognitive function. However, we can counter this by keeping ourselves or our elders engaged in activities like learning new skills or solving puzzles. These activities help maintain cognitive functions as we age. For example, it was studied that people who engage in mentally stimulating activities at an older age show improved cognitive abilities due to the brain’s plasticity.
4. Mental health and well-being: Neuroplasticity also aids in mental health treatments. Therapies designed for complex mental health issues, such as CBT, benefit from the brain’s ability to revive itself and address mental health challenges.
5. Brain health and Resilience: If you are aware of the neuroplasticity you can overcome the lifestyle’s impact on your brain’s health. Exercising regularly, eating a balanced diet, and maintaining social interactions can result in improved neuroplasticity leading to a stronger brain. Even studies have shown that aerobics enhances cognitive and neuroplasticity.

Mechanism of neuroplasticity

There is something called synaptic plasticity through which neuroplasticity works. Whenever we do something new, learn something new, or feel something for the first time, neurons (the functional units of the brain) form new connections and interact with each other. These connections are known as synapses. These synapses are rapidly changing in their shape, size, structure, and strength as per our experience. There are 2 types of synaptic plasticity:

1. When the connection between 2 sets of neurons becomes stronger on successive repeated activation with each other. It’s called LTP (long-term potentiation). It is like making any of your skills stronger as you practice them more and more.
2. Long-term depression (LTD): LTD corresponds to the weakening of the connection between the neurons due to inconsistent or less frequent activation together. It’s like eradicating the less-used connections and keeping space for more-used ones.

Factors influencing Neuroplasticity

It very obvious that neuroplasticity being complex does get affected by several factors.

• Age: Neuroplasticity occurs rapidly in children. Children and adolescents possess higher levels of neuroplasticity, which is why they constantly learn new things. This ability can continue throughout life. By engaging in mentally stimulating activities, we can enhance our neuroplasticity even as we age.
• Sleep: Optimum level of sleep is really important and non-negotiable for the brain to work effectively. Sleep resets our system, clears toxins, and strengthens neural connections formed during the daytime. Lack of sleep can damage cognitive functioning and slow down neuroplasticity.
• Stress and emotional state: Prolonged stress might have a bad impact on neuroplasticity by affecting neuron structure and functions. If the stress hormone cortisol rises it inhibits the formation of new neural connections.
• Physical activity: As said earlier exercising does show a positive effect on neuroplasticity. Aerobic exercise precisely enhances the growth factors that help in the maintenance of neurons and synapses, enhancing cognitive functions, memory and overall brain health.
• Nutrition: A balanced diet is suggested as it’s one of the factors to keep you mentally strong and support your brain’s health.

Misconceptions about neuroplasticity

These are some of the misconceptions people have about neuroplasticity:

1. That it occurs only in children.
2. That if the brain is injured, neuroplasticity will not help.
3. That it’s a quick and effortless process.
4. That all brain training gains are effective for neuroplasticity.
5. It can reverse all brain-related conditions.

Neuroplasticity is a complex yet interesting phenomenon that takes place in human brain. We are equipped with this super-power from the time we are born and it stays till we die. Educating people about neuroplasticity can be helpful in a lot of ways and is used for developing treatment procedures. It strengthens your brain and makes you the better version of yourself consistently.
