Neuroplasticity, or brain plasticity, is the ability of the brain to change and adapt in response to intrinsic and extrinsic factors. The brain can reorganize its structure, functions, and connections, and this ability is referred to as neuroplasticity. Neuroplasticity can be influenced positively or negatively by a variety of factors, including practice and training. For example, studies have shown that musical training and mindfulness practices can enhance neuroplasticity. Physical exercise has also been found to boost brain plasticity and may even promote new neuron formation. Landmark papers in 2005 and 2009 provided the first evidence of links between development, training, and white-matter plasticity in humans. This has inspired further research into the mechanisms underlying training-related plasticity.

What You'll Learn
Physical exercise and neuroplasticity
Neuroplasticity refers to the brain's malleability or ability to change and adapt in response to intrinsic and extrinsic factors. It allows nerve cells to change or adjust, and the brain to reorganise pathways, create new connections, and even generate new neurons. Neuroplasticity is most active in childhood, but it remains present throughout our lifespan.
Physical exercise has been associated with increased neuroplasticity and improved brain function. It is believed that exercise can help prevent neuron loss in key areas of the hippocampus, a part of the brain involved in memory and other functions. It may also play a role in new neuron formation in this same region. A study from 2021 suggests that physical exercise boosts brain plasticity through its impact on brain-derived neurotrophic factor (BDNF, a protein that impacts nerve growth), functional connectivity, and the basal ganglia, which is responsible for motor control and learning.
Further studies have found that exercise can improve learning and memory, as well as delay neurodegeneration, including Alzheimer's disease. Exercise helps to maintain a cerebral microenvironment that facilitates synaptic plasticity by enhancing the clearance of Aβ, a key contributor to Alzheimer's disease. It also increases the activity of Aβ degradation enzymes, preventing the aggregation of Aβ. Additionally, exercise has been shown to decrease the aging-induced activation and proliferation of microglia in the hippocampus.
Aerobic exercise, such as biking, running, or swimming, promotes the circulation of oxygen through the cardiovascular system and enhances the expression of neuroplasticity biomarkers, including BDNF, insulin-like growth factor 1 (IGF-1), and vascular endothelial growth factor (VEGF). These molecular changes upregulate cellular processes like neurogenesis and increase grey and white matter volume, leading to enhanced neuronal activity.
Overall, physical exercise is an essential pillar of mental health, influencing the structure and function of the brain. It drives neuroplasticity in a positive direction and has the potential to improve general health and well-being.

Mindfulness and neuroplasticity
Mindfulness is the act of immersing your mind in the present moment, being aware of your thoughts, feelings, and bodily sensations without ruminating over the past or future. It is a powerful tool that positively impacts both physical and mental health.
Neuroplasticity is the brain's ability to change or adjust its nerve cells in response to intrinsic and extrinsic factors. This phenomenon continues into adulthood and can be influenced positively or negatively at any age. The brain's neuroplasticity allows it to reorganize pathways, create new connections, and even generate new neurons.
Combining mindfulness with neuroplasticity can help individuals rewire their brains and increase their emotional resilience. Mindfulness practices help individuals become more aware of their thoughts and feelings, allowing them to observe and understand their mental processes. This awareness can lead to a decrease in stress, anxiety, and depression. By paying attention to the present moment, individuals can learn to regulate their emotions and attention with more ease.
Research has shown that mindfulness training can result in changes to significant brain structures, such as the hippocampus and the amygdala. The hippocampus is associated with emotion control and memory storage, while the amygdala is linked to fear, anxiety, and stress responses. Participants in studies have shown thickening in the hippocampus, indicating improved memory consolidation, and decreased grey matter in the amygdala, suggesting reduced sensitivity to potential threats.
Mindfulness practices, such as mindfulness of the breath, help individuals shift their attention from habitual thinking to body awareness. By anchoring their attention on the breath, individuals can learn to return to the present moment and develop an attitude of interest and curiosity. This repetition strengthens compassionate qualities of the mind and helps to manage mental health.
In conclusion, mindfulness and neuroplasticity work together to support human flourishing. By understanding the brain's ability to change and adapt, individuals can utilize mindfulness practices to rewire their brains, improve emotional resilience, and lead happier, healthier lives.

Neuroplasticity in adulthood
Neuroplasticity refers to the brain's malleability or ability to change. It allows nerve cells to adapt, adjust, and create new connections. While neuroplasticity is most active in childhood, it remains present throughout our lifespan, allowing our brains to continue to reorganise pathways and form new connections in adulthood.
Previously, the brain was considered stable and unchanging in adulthood, except for the inevitable cognitive decline that occurs with ageing. However, this view has been challenged by modern research, which provides clear evidence that structural changes do occur in the adult brain. These changes include the generation of new neurons and other brain cells, as well as the formation of new connections between neurons.
Factors such as stress, adrenal and gonadal hormones, neurotransmitters, growth factors, certain drugs, environmental stimulation, learning, ageing, and physical exercise have been found to influence neuroplasticity in adults. For example, studies indicate that physical exercise may help prevent neuron loss and promote new neuron formation in the hippocampus, a part of the brain involved in memory and other functions. Additionally, mindfulness practices and playing games have also been shown to foster neuroplasticity.
The discovery of adult neuroplasticity has significant implications for clinical practice. By understanding how behaviour and the environment influence brain structure and function, we can develop strategies to optimise brain health and potentially protect against or repair brain damage and disease. This knowledge can be applied to empower individuals to adopt behaviours that promote positive neuroplasticity and enhance their overall health and well-being.

Synaptic plasticity
The idea that synapses could change, and that this change depended on how active or inactive they were, was first proposed in 1949 by Canadian psychologist Donald Hebb. Because of its probable contribution to memory storage, it has since become one of the most intensively researched topics in neuroscience.
The strength of communication between two synapses can be likened to the volume of a conversation. When neurons talk, they do so at different volumes – some neurons whisper to each other while others shout. The volume setting of the synapse, or the synaptic strength, is not static, but rather can change in both the short term and long term. Short-term synaptic plasticity refers to changes in synaptic strength that occur on a sub-second timescale: a rapid up or down adjustment of the volume control that helps determine how important that connection is to the ongoing conversation, but which reverts to “normal” soon afterwards. Long-term synaptic plasticity lasts anywhere from minutes to hours, days, or years. Long-term plasticity is the dominant model for how the brain stores information—in other words, for how we create and remember new memories.
There are several underlying mechanisms that cooperate to achieve synaptic plasticity, including changes in the quantity of neurotransmitters released into a synapse and changes in how effectively cells respond to those neurotransmitters. Synaptic plasticity in both excitatory and inhibitory synapses has been found to be dependent upon postsynaptic calcium release.
Synaptic fatigue or depression is usually attributed to the depletion of the readily releasable vesicles. A key characteristic of depression at many synapses is use dependence. Higher levels of transmission are associated with larger depression, and reduction of baseline transmission (e.g., by reducing external calcium concentration) relieves depression.

Neuroplasticity and recovery from brain injury
Neuroplasticity refers to the brain's malleability or ability to change and adapt in response to intrinsic and extrinsic factors. It allows nerve cells to change, adjust, and reorganize pathways and create new connections and, in some cases, even generate new neurons. Neuroplasticity is most active in childhood as a part of normal human development but remains present throughout our lifespan.
Traumatic brain injuries can cause both direct and indirect damage to the brain. Direct damage can occur through shear injury to neurons and blood vessels, while secondary ischemia, edema, or inflammation can cause indirect harm. The blood-brain barrier, which controls the movement of molecules into the brain, often becomes disrupted following a traumatic brain injury, leading to inflammatory events that further exacerbate the injury.
The good news is that neuroplasticity plays a critical role in brain injury recovery. The brain has an incredible capacity to adapt and reorganize even long after sustaining damage. This process of neuroplasticity can aid in active recovery following brain trauma by creating new neuronal connections and pathways. For example, axonal sprouting, a type of structural plasticity, involves the expansion of new axonal branches from preexisting neurons, allowing the creation of new connections and pathways around injured regions.
Various therapies and interventions can leverage neuroplasticity to facilitate recovery from brain injuries. These include virtual reality, brain-computer interfaces, and constraint-induced movement therapy. Evidence-based behavioral techniques, such as mindfulness practices, can also drive neuroplasticity in a positive direction, fostering the brain's ability to heal and adapt.
Additionally, physical exercise has been shown to boost brain plasticity. Regular physical activity can help prevent neuron loss and promote new neuron formation in key areas of the brain, such as the hippocampus, which is involved in memory and other cognitive functions. Cardio exercises, in particular, are recommended for improving brain health and promoting neuroplasticity.
While the recovery process after a traumatic brain injury can be long, emerging evidence for neuroplasticity provides hope and a range of therapeutic options to improve symptoms and enhance life after damage.

Frequently asked questions
Neuroplasticity, also known as neural plasticity or brain plasticity, is the ability of the brain to change and adapt in response to intrinsic and extrinsic factors. It involves adaptive structural and functional changes to the brain.
Neuroplasticity is most active in childhood as it is a crucial part of normal human development. However, research has shown that many aspects of the adult brain can be altered through practice and training. For example, studies have found that musical training and mindfulness practices can contribute to increased neuroplasticity.
Neuroplasticity can have both positive and negative influences. On the positive side, it allows the brain to recover from injuries such as strokes or traumatic brain injuries (TBIs) and can aid in learning and memory. It can also lead to the development of new abilities, such as human echolocation in blind people.
