You might have encountered the term neuroplasticity in conversations about brain health or mental fitness. But what is neuroplasticity, and why does it matter?
Your brain is a dynamic, ever-changing ecosystem of connections that constantly rewire themselves based on your experiences, behaviors, and thoughts. This means that every time you learn something new, your brain creates new pathways or strengthens existing ones. It’s why you can pick up new skills, form habits, or recover after a severe head injury.
Neuroplasticity is at work, whether you’re learning a new language, recovering from a stroke, or simply trying to break a bad routine. Understanding how the process works will empower you to optimize your brain’s ability to change and grow.
So, what is neuroplasticity, and how does it work?
Neuroplasticity generally refers to the brain’s incredible ability to change throughout life. This process, also called brain plasticity, operates on the cellular level and relies on the neurons in your brain. Before you start wondering, “What is neuroplasticity on the cellular level?” here’s a practical example.
Think of your brain as a vast network of interconnected highways. The vehicles on these roads are referred to as neurons. These specialized cells transmit information, enabling you to think, feel, and move. The junctions where these neurons meet are called synapses.
The brain has more than a billion neurons that communicate through synapses. When you learn something new or experience something significant, your brain responds by reorganizing its neural pathways. In short, the more you engage in a particular activity, the stronger the link between relevant neurons. Conversely, rarely used connections may weaken or disappear entirely.
Brain plasticity manifests in everyday life in countless ways. Consider trying to master an advanced yoga pose. With repeated attempts, the brain strengthens the connections between the motor cortex and muscles, resulting in improved coordination and balance. When you stop practicing, those pathways may weaken, making it harder to achieve the same flexibility.
And it’s not just learned skills that matter. Even everyday activities like taking a new route home or brushing your teeth with your less dominant hand can trigger neuroplasticity.
Types of neuroplasticity
The brain adapts in various ways depending on the situation, giving rise to different kinds of neuroplasticity. There are two main types.
Structural plasticity
Structural plasticity involves transformations in the brain’s physical structure, typically in response to learning and experience. Structural plasticity is most evident in people who’ve honed specific skills through repeated practice, such as musicians and athletes.
This is because when you learn something new, your brain forms new connections between neurons. Over time, these connections lead to changes in the brain’s physiology. For instance, there could be a notable increase in gray matter in regions associated with the skills you’re acquiring.
Functional plasticity
Functional plasticity refers to reorganizing existing neural networks to compensate for changes in function. It involves the brain’s ability to shift processes from one area to another, usually in response to damage.
If a particular section is injured, other parts may take over the lost functions. This type of plasticity is crucial in hastening recovery from strokes, traumatic brain injuries, or conditions that affect brain functionality.
Factors that influence neuroplasticity
Several factors influence how effectively your brain can undergo neuroplasty, as well as the degree to which you experience it.
Age
Neuroplasticity is more profound in childhood, as the brain is highly adaptable during this period of rapid growth. This is why children learn new languages or master skills faster than adults.
However, far from old beliefs, neuroplasticity doesn’t disappear as you age. The brain retains its ability to adjust even in later years. Adults undergo significant neuroplastic changes, especially when actively engaging in new learning experiences or rehabilitative practices.
Physical health
Regular physical activity, healthy foods rich in brain-healthy nutrients, and adequate sleep contribute to optimal brain function:
- Regular exercise supports the growth of new neutrons and maintains existing connections, leading to improved cognitive performance.
- During sleep, your brain consolidates memories and strengthens the neural links formed throughout the day.
- A balanced diet comprising recommended amounts of carbohydrates, proteins, vitamins, and healthy fats provides the nutrition the brain needs to thrive. Some foods are known to boost neuron health, such as blueberries, avocado, salmon, and dark chocolate.
Learning and experience
Engaging in mentally boosting activities like problem-solving or even learning to play a musical instrument challenges the brain to form new links, promoting neuroplasticity. In short, the more you practice a skill, the more your brain strengthens the neural connections associated with that activity.
Environment
Your surroundings also affect neuroplasticity. A stimulating environment rich in new experiences, social interactions, and challenges helps the brain change. On the other hand, monotonous or stressful conditions can hinder the brain’s ability to build new connections.
Research shows that the habits or behaviors one forms during prolonged exposure to chronic stress or trauma in childhood can persist into adulthood, negatively impacting neuroplasticity. This predisposes one to long-term mental illnesses like depression and PTSD.
What is neuroplasticity’s role in health?
The connection between neuroplasticity and your health is crucial. The brain’s ability to rewire on cue is fundamental to mental and physical well-being.
Mental health
Mental disorders like depression, anxiety, and PTSD have a connection to shifts in brain structure and function. Since mental disorders are one of the leading causes of disability in the world, neuroplasticity plays a significant role in alleviating these debilitating disorders. Thanks to the brain’s plasticity, these mental illnesses are not fixed.
Therapies like cognitive behavioral therapy (CBT) and mindfulness practices instigate positive changes in the brain, enabling you to manage and overcome mental health challenges. CBT, for example, works by helping people identify and alter negative thought patterns, which in turn rewires their brains to think in more optimistic, adaptive ways.
Physical recovery
Neuroplasticity empowers the brain to reroute functions, effectively compensating for the affected processes after an illness that affects the brain, like a stroke or a severe head injury. Your brain can build new neural connections through consistent, targeted rehabilitation exercises. This can improve motor skills, speech, and cognitive processes. It is through the brain’s plasticity that stroke patients can regain lost abilities over time.
Learning and memory
Plasticity contributes largely to learning and memory formation. When you learn something, your brain alters its structure to store this data. Repeated exposure and continuous practice enable you to master new skills or knowledge. By actively engaging with information and experiences, you strengthen the neural pathways that keep your brain sharp and encode memories.
Healthy aging
Neuroplasty becomes essential for preserving cognitive function as you age, enhancing your quality of life. Lifelong learning, staying physically active, and maintaining strong social relationships can help keep the brain adaptable and resilient. This minimizes susceptibility to age-induced cognitive decline issues, including dementia and Alzheimers.
How to harness neuroplasticity for better health
To some extent, you can control how much you benefit from the brain’s ability to adapt to changes. Certain intentional lifestyle interventions support neuroplasticity, promoting better health, including:
- Keep learning: If you don’t use it, you risk losing it. Try to learn something new or hone existing skills to keep the brain active. Make it a habit to participate in mentally engaging activities like solving puzzles, brain games, or teasers to promote plasticity.
- Exercise regularly: Physical activity is a potent trigger for neuroplasticity. It encourages the growth of new neurons and boosts existing pathways, supporting brain health. So, get at least 30 minutes of vigorous or moderate exercise most days of the week.
- Focus on nutrition: In addition to eating a balanced diet, prioritize foods that contain brain-boosting nutrients that support optimal mental health, such as vitamins B, C, and E, omega-3 fatty acids, and antioxidants.
- Get enough sleep: Since neural pathways are strengthened during sleep, aim for at least seven hours of uninterrupted sleep every night to improve your brain’s plasticity.
- Practice mindfulness: Regular meditation increases gray matter volume in brain regions responsible for learning, memory, and emotional regulation. Add mindful practices to your daily routine to enhance your brain’s capacity to respond to new challenges, effectively alleviating mood and mental health disorders.
Understanding the connection and benefits of neuroplasticity to your health empowers you to take control of your mental well-being by making choices that support brain plasticity.
