Neuroplasticity—the brain’s ability to change, adapt, and grow—is one of the most powerful concepts in modern neuroscience. During All Saints University’s Research Day, students Awe J.B., Odesanya O., Durotoye A., and Dr. Adewara E.O. presented a compelling literature review exploring how stress, learning, physical activity, fasting, and diet can influence this essential brain function.
What Is Neuroplasticity?
Neuroplasticity is the brain’s capacity to reorganize itself by forming new neural connections. This process plays a vital role in learning, memory, and recovery from injury. But the brain’s ability to adapt isn’t fixed—it’s deeply influenced by our daily habits and environment.
Research Focus and Method
The team conducted a systematic literature review, analyzing 160 peer-reviewed articles that met specific inclusion criteria. The research centered on five lifestyle-related factors:
- Stress
- Learning
- Physical activity
- Fasting
- Diet
Each article was assessed using the CASP qualitative tool to ensure credibility and scientific rigor.
Key Findings
1. Stress
- Negative effects: Chronic stress reduces neurogenesis, shrinks the hippocampus and prefrontal cortex, and impairs memory and emotional regulation.
- Biological impact: Elevated stress hormones (like cortisol) disrupt normal brain signaling and inhibit plasticity.
2. Learning
- Learning strengthens and creates new neural pathways.
- Long-Term Potentiation (LTP), a key process in memory and learning, is enhanced by repeated exposure to mentally stimulating tasks.
3. Physical Activity
- Regular physical activity improves hippocampal volume and cognitive function.
- Exercise increases the release of BDNF (Brain-Derived Neurotrophic Factor), which supports synaptic plasticity.
- Activities like dancing improve white matter integrity and attention.
4. Fasting and Diet
- Intermittent fasting helps reduce inflammation and oxidative stress while promoting mitochondrial function.
- Nutrients such as curcumin, omega-3 fatty acids, and polyphenols support brain health and boost BDNF.
- Balanced diets prevent brain atrophy and enhance memory retention.
Why This Matters
This research highlights that neuroplasticity is ongoing throughout life—not just in childhood. Our lifestyle choices can either enhance or impair this vital brain function.
By understanding how daily habits like diet, exercise, and mental stimulation affect the brain, we can take control of our cognitive health. It also opens doors for potential treatment strategies for neurodegenerative diseases, such as Alzheimer’s and Parkinson’s, by using non-pharmacological interventions.
Final Thoughts from the Authors
“Neuroplasticity is a common process in every human brain. Acquiring knowledge about the different factors that contribute to positive and negative changes… will go a long way in helping people take charge of their neurologic function.”
The review calls for increased awareness and education around lifestyle medicine and its impact on brain health.
