Neuroplasticity, also referred to as brain plasticity, is the brain’s ability to adapt and alter due to experience. It is an umbrella term referring to the brain’s ability to grow, reorganize, and change its neural networks. This can involve functional changes due to brain damage or structural changes due to learning. This phenomenon is at the core of learning, memory, recovery from brain injuries, and even personal growth.
“Plasticity” refers to the brain’s malleability or ability to change. “Neuro” refers to neurons, the nerve cells that are the building blocks of the brain and nervous system. Thus, neuroplasticity allows nerve cells to change or adjust.
The human brain is composed of approximately 100 billion neurons. Early researchers believed that neurogenesis, or the creation of new neurons, stopped shortly after birth. However, it is now understood that this is not the case. While are brains are more adaptable as infants and children, neuroplasticity occurs throughout an individual’s entire lifespan.
Neuroplasticity is typically placed in two categories: structural and functional.
This type refers to the brain’s ability to create new neurons, connect them to other neurons, and integrate them into the central nervous system. This occurs regularly throughout one’s life as the brain adapts to circumstances and knowledge. For example, if a person is learning a new language or acquiring a new skill, they will experience structural neural changes.
At the microscopic level, this type of neuroplasticity can occur in the synapses (connections between neurons), and in the neurons themselves. Synapses can become stronger or weaker based on the frequency and intensity of neural activity. Neurons can physically change their structure, including the growth of new dendrites (branch-like extensions) and axons (nerve fibers). This structural flexibility is what allows the brain to adapt to new challenges and experiences.
This type occurs as an adaptation to irregular circumstances. For example, when part of the brain is injured, neurons in another area of the brain may take on the tasks that the injured area was responsible for. Functional neuroplasticity can also refer to changes in the brain resulting from illness or hereditary conditions.
Understanding neuroplasticity has profound implications for various aspects of our lives:
Neuroplasticity underscores the idea that learning is a lifelong process. It encourages a growth mindset, where individuals believe in their ability to acquire new knowledge and skills at any age.
Neuroplasticity-based therapies are used in rehabilitation programs for individuals recovering from stroke, traumatic brain injuries, and other neurological conditions. Cognitive remediation also relies on neuroplasticity to help individuals with psychological conditions to regain cognitive skills that may have been impaired. These types of cognitive therapy promote the rewiring of damaged neural circuits.
Engaging in activities that challenge the brain, such as cognitive exercises, learning a new language, or playing musical instruments, can enhance cognitive abilities and promote neuroplasticity.
Recognizing the brain’s adaptability can offer hope to those dealing with mental health challenges. Therapy and interventions can lead to positive changes in neural circuits and emotional well-being.
The concept of neuroplasticity supports the idea that personal growth and self-improvement are achievable goals. By setting intentions and engaging in deliberate practice, individuals may rewire their brains to align with their desired outcomes.
For example, it’s easy to limit ourselves by thinking something like “I never finish the books I start reading.” In actuality, the science of neuroplasticity tells us that it is possible to deliberately change the structure that habits create in the brain. If you want to improve your ability to finish a book, you must engage in a deliberate practice of finishing books. Then, it becomes possible for your brain to rewire this ability, so that it becomes easier and easier to finish reading a book.
Neuroplasticity is a testament to the brain’s incredible ability to adapt, learn, and recover. It highlights the importance of lifelong learning, resilience, and the potential for positive change, even in the face of injury or impairment.
Whether you are interested in boosting your cognitive abilities, recovering from a brain injury, or simply exploring the limitless potential of your brain, neuroplasticity is a concept that offers hope and exciting opportunities for growth.
