Neuroplasticity, also known as neural plasticity or brain plasticity, is the brain's ability to adapt and change. It involves functional and structural changes, allowing the nervous system to reorganise its structure, functions, or connections. Neurogenesis, or the creation of new neurons, was once believed to stop shortly after birth, but it has since been discovered that the brain can continue to produce new neurons. This process of neurogenesis occurs in parts of the brain such as the hippocampus, aiding in learning, memory, and recovery from brain injuries. Enhancing neuroplasticity and neurogenesis can be beneficial for brain health and cognitive function, and this can be achieved through various means such as exercise, sleep, learning new skills, and engaging in activities like gaming and learning a musical instrument.

Exercise regularly, especially aerobic exercise
Exercise, particularly aerobic exercise, is a powerful tool for improving brain plasticity and neurogenesis. The brain is highly susceptible to environmental changes and external stimuli, and physical exercise (PE) is one such factor that can influence the production of neurotrophic factors, leading to enhanced brain functionality.
Regular aerobic exercise, such as running, has been shown to increase neurogenesis and improve cognitive function. This is due to the activation of specific transcriptional factors linked to cell metabolism and the increase in certain cellular components, such as CREB, AKT, and cAMP, which play a crucial role in central nervous system development. The stimulation of AKT and phosphatidylinositol 3 kinase (PI3K) through aerobic exercise has been associated with improvements in memory and motor control.
Additionally, aerobic exercise can enhance neuroplasticity by altering the synaptic structure and function in various brain regions. It modulates systems like angiogenesis and glial activation, which are known to support neuroplasticity. Exercise also helps maintain a cerebral microenvironment that facilitates synaptic plasticity by reducing the presence of Aβ, a key contributor to Alzheimer's disease (AD) pathogenesis.
The benefits of aerobic exercise extend to delaying the onset of neurodegenerative diseases like Alzheimer's. Exercise elevates VEGF transcription, mRNA, and protein in the brain, supporting neurogenesis and potentially protecting neurons against AD. Furthermore, aerobic exercise increases hippocampal volume, countering age-related volume loss in older adults.
To fully stimulate your brain, it is recommended to combine aerobic exercise with activities that challenge your focus and coordination, such as martial arts, dance, rock climbing, or yoga. This combination can help improve brain plasticity and neurogenesis, leading to enhanced cognitive function and overall brain health.

Learn a new language
Learning a new language is a powerful way to improve brain plasticity and neurogenesis. The human brain is inherently plastic, meaning it has the capacity to change and adapt throughout life. This adaptability is fundamental to brain function, enabling us to acquire new skills, knowledge, and the ability to adjust to new environments.
Neuroplasticity, or brain plasticity, is the brain's remarkable ability to reorganize and rewire itself in response to new experiences and learning. When we learn a second language, our brain undergoes extensive neuroplastic changes, forming new neural connections and pathways. This process enhances our cognitive abilities, allowing us to develop linguistic skills and strengthen existing neural connections.
The impact of learning a new language goes beyond language functions. These changes also affect the executive processing part of the brain, which is responsible for planning future behaviors, monitoring and changing behavior, and switching between tasks. Bilingualism has been linked to higher cognitive reserve, better executive control, and changes in brain structure and function when compared to monolingual individuals.
Studies have shown that learning a second language can lead to increases in hippocampus volume, which is significant as the hippocampus plays a crucial role in episodic memory. Additionally, older bilingual adults have been found to have greater left hippocampal volume than monolingual individuals, suggesting a potential delay in dementia onset.
However, it is important to note that the process of learning a new language may differ between younger and older adults. While language learning in younger adults has been shown to impact functional connectivity and cortical thickness, older adults may not rely on the same neural mechanisms, resulting in different patterns of brain plasticity.
Overall, learning a new language is a highly effective way to enhance brain plasticity and promote cognitive enhancement at any age. It is a dynamic process that not only improves our language skills but also has far-reaching benefits for our overall brain health and functionality.

Play video games
Playing video games can positively impact neuroplasticity and neurogenesis in the brain. Neuroplasticity refers to the brain's ability to adapt, reorganise, and change through experience. It involves two types of neuroplasticity: structural and functional neuroplasticity. Structural plasticity changes the strength of neuron connections, while functional neuroplasticity permanently changes neuron connections, creating new pathways.
Video games can induce structural brain plasticity, leading to grey matter changes. For example, playing Super Mario 64 was found to significantly increase grey matter in the hippocampus, which is involved in spatial processing and navigation. The right prefrontal cortex and the cerebellum also exhibit neurogenesis and neuroplasticity improvements, enhancing functions such as memory formation, strategic planning, and fine motor skills.
Video games provide a rich environment that fosters learning and brain plasticity. They engage attentional control and reward processing, which are key mechanisms in driving plastic changes. These changes may lead to the establishment of functional networks that support performance and adaptation to new tasks. Additionally, video games can enhance learning more effectively than non-game interventions, as seen in a study using a computer-based language-learning game with Finnish-speaking children.
It is worth noting that not all video games are equal in their impact on the brain. While some games may improve brain plasticity and neurogenesis, others may have negative effects. For instance, a 2018 study found that playing first-person shooting games reduced grey matter in the hippocampus. Therefore, it is essential to be mindful of the type of video game being played and to maintain a balance with real-world activities and social connections.
Overall, playing certain video games can be a fun and engaging way to promote neuroplasticity and neurogenesis in the brain, leading to potential improvements in cognitive functions and overall brain health.

Play a musical instrument
Playing a musical instrument is a complex activity that engages multiple brain regions. It is a multisensory and motor experience that requires the acquisition and maintenance of a range of skills. This makes musicians excellent models for studying the effects of acquiring specialized skills. For example, musicians learn and repeatedly practice the association of motor actions with specific sound and visual patterns (musical notation) while receiving continuous multisensory feedback. This association learning can strengthen connections between auditory and motor regions, such as the arcuate fasciculus, and activate multimodal integration regions, such as those around the intraparietal sulcus.
Learning to play a musical instrument can induce structural and functional changes in the brain. These changes are reflected in the development of high cognitive functions and abilities specific to the instrument played. For instance, keyboard players show structural changes in somatosensory areas related to the hands or fingers, while wind instrument players exhibit modifications in mouth-related brain regions. Playing a musical instrument also involves higher-order cognitive functions such as memory, attention, emotion, and the processing of musical syntax.
The complexity of music performance requires a unique and multi-system involvement from the human brain. Playing an instrument demands sensorimotor adaptations, such as mapping specific movements to auditorily perceived outcomes, following the rules of musical harmony, aesthetics, and pleasure. It involves both feed-forward and feedback interactions between the integrated multisensory input (tactile, proprioceptive, auditory, and visual) and motor output. The highly rewarding nature of musical performance likely promotes learning and drives brain plasticity.
Research has shown that musical training can result in plastic changes in the brain, even in adults. These changes may be more prominent in those who began training early in childhood. For example, musicians who started training before the age of seven showed increased mean diffusivity in the corticospinal tract compared to those who started later or non-musicians. Playing a musical instrument provides a useful framework for studying multimodal brain plasticity and the dynamics of neuroplastic processes.
