Neuroplasticity: Harnessing Your Brain's Ability to Learn and Adapt

Neuroplasticity, the brain's remarkable ability to reorganize itself by forming new neural connections throughout life, provides the foundation for learning new skills and adapting to change — a particularly empowering thought for professionals who thrive on continual growth.

The Science Behind Neuroplasticity

Once believed to be a static organ, the brain is now understood to be dynamic, rewiring itself in response to our experiences. From morphological changes in brain areas, alterations in neuronal networks including changes in neuronal connectivity as well as the generation of new neurons, to neurobiochemical changes, new studies have shown how the brain can change in response to training.

However, neuroplasticity encompasses more than just the creation of new connections; it also involves the pruning of synapses that are no longer needed, optimizing the brain's network. That is necessary when we want to let go of bad habits for example, neuronal shrinkage, decrease in spine density or dendritic complexity are intricately tied to brains inherent capacity for neuroplasticity.

When we talk about shrinkage of brains gray matter it seems as an impairment, but during pregnancy it is associated with adaptive response to support the cognitive and emotional demands of motherhood (Hoekzema et al., 2017). It endure for at least 2 years post-pregnancy and not necessarily indicates a lack of cognitive function - althought pregnants could feel some lack of memory sometimes.

Practical Tips for Leveraging Neuroplasticity

So, how can we leverage this intrinsic power of the brain? Here are practical strategies informed by scientific insights and ancient wisdom:

• Embrace Lifelong Learning: Challenge your brain with new skills. Whether it’s learning a new language or a musical instrument, such cognitive challenges can stimulate neural growth (Draganski et al., 2004). Don′t want to engage in such huge learning? Start smaller: learn a new skill for your work or use your non-dominant hand to brush your teeth, eat or wash the dishes. Anything that need your full attention is a good training.
• Diversify Your Skill Set: Engage in cross-training. Just as athletes benefit from a varied exercise regimen, professionals can build a more resilient brain by diversifying their skill set, from artistic activities, as drawing and painting, to coding (Ballesteros S. et al., 2018), engage in the practice of skills that you are not used to. Training apps as Lumosity, Peak and CogniFit Brain Fitness provide free access to a range of cognitive training exercises.
• Mindful Repetition: Practice makes perfect, and repetition is the key to mastery. However, it's the mindful repetition that matters. As you practice, stay present and attentive to refine your skills and forge stronger neural pathways.
• Healthy Habits, Healthy Brain: Prioritize sleep, nutrition, and exercise. The brain requires quality fuel and rest to optimize its plasticity (Fuchs and Flügge, 2014).REM sleep has multifaceted functions in brain development, learning and memory consolidation, by selectively eliminating non-used synapses and maintaining newly formed synapses (Li et al., 2017). The excessive food intake in the standard western nations seems to be almost as harmful to cognition as the lack of it in poor countries, so eat frugally and consider fasting - I will talk more about it in the future. A plant-based diet, diversifying vegetables, legumes, cereals, nuts and seeds should provide all the nutrients you need for a good cognition. Ensure to get enough fat, specially omega-3 DHA and EPA, B-complex vitamins, and minerals, as magnesium and zink, that are essentials for brain function. Nutrients such as omega-3 fatty acids and antioxidants have been linked to enhanced cognitive function and preservation (Ekstrand B. et al., 2021). Both aerobic and resistance training could enhance neuroplasticity and cognitive function by increasing neurotrophic factors - which support the growth, survival, and differentiation of developing and mature neurons - and increasing cerebral blood flow, and cerebrovascular resistance (Fernandes et al., 2020).
• Stress Management: While a certain level of stress can be stimulating, chronic stress can inhibit neuroplasticity. Techniques such as controlled breathing, progressive muscle relaxation and guided imagery, can mitigate stress and foster a conducive environment for brain growth (Dusek et al., 2008).
• Meditation: The practice has been associated with positive effects on brain structure and function. Either mindfulness exercise or mindfulness meditation can increase peripheral brain-derived neurotrophic factor (Gomutbutra P. et al. 2020).Focused attention meditation can lead to alterations in the brain's functional networks: the default mode network, associated with internal modes of cognition, such as self-reflection; fronto-parietal network, involved in sustained attention, complex problem-solving, working memory, and cognitive control; and sensory-motor network, responsible for processing external physical stimuli, feeling internal sensations, evaluating the senses, and producing a motor response (Kajimura et al., 2020).Mindfulness meditation induces long-lasting changes in brains structural connectivity, higher gamma oscillations, associated with the synchronization of neural activity in the brain and the control of connectivity between brain regions, and theta waves, considered to be important for promoting adaptive, complex behaviors such as learning and memory (Lardone A. et al. 2018).

In conclusion, neuroplasticity allows us to adapt our brains to perform tasks better. It's a testament to our potential for change and growth and it is molded by new experiences, the more different abilities we experience and train the more different connections we activate and reinforce in our brain, what facilitates to acquire new skills. Consider to engage in cognitive training and adapt your habits for an optimum environment for your brain function.

Engaging in a healthy diet, mindfulness, body movement and meditation has long been suggested by ancient Eastern cultures, knowledge that Western society has only recently come to apply through the backing of science. Since it positively affects the vitality and longevity of the body in general, it's smart of us to follow the recommendations.

Remember, the journey to a more adaptable brain is ongoing — every challenge faced, every new skill learned, every good habit formed, and every new experience, is a step toward a stronger, more resilient mind.
