Ever wondered why children can learn a lot of new things, but older adults are set in their ways and can’t change? This is because of a specific quality of human brain activity called neuroplasticity. The more neuroplastic a brain is, the more receptive it is to new experiences and learning new things.
However, it’s not entirely true that older adults can learn something new. Adults can have high levels of neuroplasticity even late in life.

Understanding Neuroplasticity
Neuroplasticity is a property of the brain that allows it to rewire itself and react to things that happen to it. This helps it learn new things, such as in school, a class, or in any new experience.
The human brain has relatively high levels of neuroplasticity when we’re children, but age-related brain degeneration tends to decrease as people age. Children have to learn many new things in a relatively short time, so having high neuroplasticity helps children develop the skills they’ll need as they grow up.
Neuroplasticity decreases as people get older, but it’s possible to maintain high levels of neuroplasticity later in life.
Mechanisms Of Neuroplasticity
Another way to understand neuroplasticity is that it’s a measure of something. Whenever you try to learn something new or get better at a skill you already have, your brain forms new neural connections.
Your brain might also forge these connections in response to an injury. For example, if you suffer from head trauma, you may find it difficult to perform specific tasks or access particular memories. Neuroplasticity can help you access skills or memories you once thought lost.
Your brain creates or reinforces these neural connections in specific ways depending on how or what you need to learn or re-learn. There are several ways your brain can do this:
Synaptic Plasticity
- Synaptic Strengthening: Repeated use of certain neural pathways strengthens the synapses in these pathways, enhancing their efficiency.
- Synaptic Pruning: Conversely, synapses that are rarely used are weakened and eventually eliminated, a process known as synaptic pruning. This helps the brain conserve resources and focus on more frequently used neural connections.
CORTICAL REMAPPING
- Functional Reorganization: If a part of the brain is damaged, other areas can sometimes adapt and take over its functions. This is particularly evident in cases of brain injury or sensory deprivation (e.g., blindness or deafness).
- Compensatory Masquerade: Sometimes, the brain develops new strategies to accomplish the same task, rather than directly taking over the function of a damaged area.
NEUROGENESIS
Traditionally, people believed that new neurons could not be generated in adulthood, but research has shown that neurogenesis does occur in certain brain regions, like the hippocampus, which is crucial for learning and cognitive abilities.
CHANGES IN NEUROCHEMICAL SYSTEMS
Changes in the levels of various neurotransmitters (chemical messengers in the brain) can alter neural plasticity, influencing learning and mood regulation.
CHANGES IN INTRINSIC NEURONAL EXCITABILITY
The intrinsic excitability of neurons (how easily a neuron fires) can change, which influences how effectively neural networks communicate.
AXONAL SPROUTING
When a neuron is damaged, other neurons can extend new axonal projections to form connections with neurons that were previously connected to the damaged cell.
MYELINATION
The process of forming a myelin sheath around the axons of neurons increases the speed and efficiency of electrical signal transmission.
DENDRITIC BRANCHING
Neurons grow new dendritic branches, increasing their ability to form connections with other neurons.

Factors Influencing Neuroplasticity
Just like your health, neuroplasticity is affected by several factors, including your health, environment, and even what you do in your everyday life.
- Age: Children generally have high levels of neuroplasticity. It’s still possible to learn new skills as an adult, but decreasing neuroplasticity can make it difficult.
- Learning and Experiences: Engaging in new learning activities and diverse experiences can stimulate brain imaging changes, enhancing neuroplasticity even as an adult.
- Stress and Emotions: Chronic stress can negatively affect neuroplasticity, while positive emotions and stress management can enhance it.
- Physical Activity: Regular exercise is known to boost the brain function and neuroplasticity, likely through increased blood flow and neurotrophic factors.
- Social Interactions: Socializing and maintaining relationships contribute to cognitive health and can positively influence neuroplasticity.
- Nutrition and Diet: A healthy diet, rich in essential nutrients, supports brain health and can enhance neuroplastic capabilities.
- Sleep: Adequate sleep is critical for neuroplastic processes, particularly those involved in memory consolidation and learning.
Neuroplasticity Mindfulness: Not All Positive
Neuroplasticity is an excellent way to measure how well we learn new things or unlearn old ones. However, having high levels of neuroplasticity can also leave someone open to learning harmful habits, skills, or beliefs. As neuroplasticity decreases, it can become difficult to change negative behaviors if they’ve already been learned.
What Is Mindfulness?
Mindfulness is a mental practice that encourages people to actively use their brain to be in the present moment. To use a metaphor, it’s the difference between “looking vs seeing”. When you only look at something, you simply acknowledge its presence. Conversely, “seeing” something means being able to observe something and understand several details about it.
Mindfulness has some roots in meditative practices. However, it’s not limited to quiet meditation — mindfulness can be used outside of meditation practices and all throughout ones everyday life.
Mindfulness Techniques
-
Focused Breathing: This is a form of mindfulness training that involves concentrating solely on your breath, and observing the inhalation and exhalation process without attempting to change it. It is a form of meditation training that anchors the mind in the present moment, reducing mind wandering distractions and promoting a sense of calm.
- Body Scan Meditation: In this practice, attention is sequentially directed to different parts of the body, noting sensations without judgment. It fosters a heightened awareness of bodily sensations based on somatic psychology techniques and can lead to a deeper understanding of physical emotion control and stressors.
- Mindful Observation: This involves selecting an object within your immediate environment and focusing all of your attention on it, observing it in detail. This practice has the brain function that helps in cultivating a deep sense of presence and self-awareness, encouraging a disconnection from internal thoughts and worries.
The Science Behind Mindfulness
Mindfulness practice has been shown to reduce activity in the amygdala, which is the brain region responsible for processing fear and stress, leading to decreased anxiety and stress responses. Functional MRI studies indicate that mindfulness increases gray matter density in the hippocampus, which is crucial for learning and memory, and enhances connectivity in the brain’s default mode network, associated with self-referential thoughts and mind-wandering.
Regular mindfulness practice can lower blood pressure and improve immune cognitive functions, demonstrating its beneficial physiological effects. Neuroscientific research also suggests that mindfulness can improve emotional regulation by enhancing the ability of the prefrontal cortex to modulate emotional responses generated in the limbic system.
Mindfulness-based interventions have been effective in reducing symptoms of various mental health conditions, including depression, anxiety, and PTSD. Cognitive benefits, such as improved attention, concentration, and decision-making, have been linked to mindfulness training and practices beneficial for cognitive functioning.

Neuroplasticity And Mindfulness – A Synergistic Relationship
Engaging in mindfulness meditation and training and practice can help your brain build or maintain neuroplasticity. As an adult, this means that you can learn to adapt to new environments and experiences or help you learn new skills.
Where neuroplasticity is a biological property of how our brains work inside the brain region, mindfulness training is a practice we can use to actively keep our minds sharp. These two concepts, when used together, can help people retain or improve their cognitive control and abilities or help with emotion control and stress management.
Mindfulness And Brain Structure
Research has demonstrated that mindfulness can lead to structural changes in areas of the brain network that are associated with memory, empathy, and stress regulation. For instance, mindfulness meditation has been linked to increased gray matter density in the left hippocampus, known for its role in learning and working memory capacity, and decreased gray matter in the amygdala, which is involved in stress and anxiety inside the brain networks.
Enhancing Neuroplasticity Through Mindfulness
Mindfulness can be seen as a tool to harness the brain’s plastic nature. By cultivating mindfulness, individuals can actively influence their brain’s wiring, leading to more adaptive, positive patterns of thought and behavior.
Practical Tips For Harnessing Neuroplasticity Through Mindfulness
Incorporating mindfulness training into your daily routine can be a powerful way to engage neuroplasticity for positive mental health outcomes. Here are some practical tips:
Daily Mindfulness Practices
Simple exercises, such as spending a few minutes each day focusing on your breath or engaging in mindful walking, can be a good start. The key is consistency and intention.
Mindfulness and Habit Formation
Mindfulness can aid in forming new, positive habits and breaking old, negative ones. By becoming more aware of your thoughts and actions, you can make changes that reinforce positive neural pathways.
Neuroplasticity and Mindfulness
The exploration of neuroplasticity and mindfulness offers a glimpse into the remarkable adaptability of the human brain and the brain cells or in the cerebral cortex, and the power of our minds to shape our mental experiences. By understanding and applying these concepts, we can unlock the potential for significant positive change in our mental health and overall well-being. Doing mindfulness research is also important.
The journey of understanding and harnessing the power of neuroplasticity and mindfulness is ongoing, but the potential for transformative growth and healing is immense.
