Plasticity in the human body, also referred to as neuroplasticity, neural plasticity, or brain plasticity, is the ability of the brain to adapt and reorganise its neural connections and functions. This process is influenced by both internal and external factors, including genetics, environment, learning, and sensory experiences. Neuroplasticity allows the brain to create new neural connections, adapt to injuries, and compensate for cognitive or sensory deficits. It is most active during childhood development, but it continues throughout our lives, demonstrating the brain's remarkable capacity for change and adaptation.

What You'll Learn
Neuroplasticity
Practices such as mindfulness, physical exercise, and playing games have been found to promote neuroplasticity. For instance, physical exercise can boost neuroplasticity by influencing the brain-derived neurotrophic factor (BDNF), a protein that impacts nerve growth and functional connectivity. On the other hand, certain factors like substance use, trauma, and diseases can negatively impact neuroplasticity, leading to detrimental changes in the brain.

Developmental plasticity
Neuroplasticity, or brain plasticity, is the ability of the brain to reorganise and rewire its neural connections, allowing it to adapt and function differently. This process can be influenced by various factors, such as learning new skills, experiencing environmental changes, recovering from injuries, or adapting to sensory or cognitive deficits.
During development, the central nervous system acquires and stores information, allowing for the adaptation of neural connections to accommodate new knowledge and experiences. This plasticity shapes traits early in life that typically remain permanent. For example, in the case of vision loss, the visual cortex in blind people may undergo cross-modal plasticity, enhancing other senses.
Additionally, human pubertal development is an example of developmental plasticity, where internal and external factors alter the neuromodulatory system controlling puberty. Onset and timing are influenced by ecological conditions, such as resource availability and stress.
Furthermore, developmental plasticity in child growth and maturation can be influenced by constantly changing life conditions and environments. This includes internal signals like hormones and external factors like nutrition and stressors, impacting energy metabolism, longevity, and fertility.

Physical exercise and neuroplasticity
Neuroplasticity, or brain plasticity, is the ability of the brain to reorganise and rewire its neural connections, allowing it to adapt and function differently. Neuroplasticity can occur as a result of learning new skills, experiencing environmental changes, recovering from injuries, or adapting to sensory or cognitive deficits.
Physical exercise has been shown to have a positive impact on neuroplasticity. It promotes the growth of new connections between cells in important cortical areas of the brain. Exercise also increases growth factors, making it easier for the brain to form new neuronal connections. This has been demonstrated in studies showing that physical exercise increases brain-derived neurotrophic factor (BDNF), a protein that impacts nerve growth, and functional connectivity.
The benefits of physical exercise on neuroplasticity are also seen in the context of cognitive functions and learning. Exercise facilitates neuroplasticity, enhancing an individual's capacity to respond to new demands with behavioural adaptations. This can lead to improved executive functions and memory, as well as potential cognitive benefits such as enhanced learning and the acquisition of new skills.
Additionally, physical exercise may help to maintain the neuro-cognitive benefits of interventions. For example, combining physical and cognitive training might result in a mutual enhancement of both. Furthermore, to sustain the neuro-cognitive advantages induced by physical activity, an increase in cardiovascular fitness levels must be maintained.
The U.S. Department of Health and Human Services recommends getting at least 150 minutes of moderate-intensity cardio exercise per week, such as walking, dancing, swimming, or cycling, and a minimum of two days of strength training. This prescribed exercise regime can promote neuroplasticity and improve brain function.

Trauma and neuroplasticity
Neuroplasticity, also referred to as neural plasticity or just plasticity, is the ability of the brain to change through growth and reorganisation. It is the brain's ability to reorganise and rewire its neural connections, enabling it to adapt and function differently from its prior state. This process can occur in response to learning new skills, experiencing environmental changes, recovering from injuries, or adapting to cognitive deficits.
Traumatic experiences can cause detrimental changes in the brain. People who have experienced trauma may go into fight, flight, or freeze mode when exposed to triggers that remind them of their trauma, even if they are not in any physical danger. Trauma can also cause a decrease in activity in Broca's area, a region in the neocortex responsible for speech, while increasing activity in the right side of the brain, where memories associated with sound, touch, and smell are stored. This can cause trauma to be experienced as fragmented memories of images, sensations, sounds, and emotions.
However, neuroplasticity can help those struggling with trauma to change their neural pathways and develop healthier coping mechanisms. Small changes repeated frequently can rewire the brain and strengthen new neurons, creating new, healthy habits that override the wired-in responses caused by trauma. Therapies such as Eye Movement Desensitization and Reprocessing (EMDR) therapy can help individuals achieve this goal. EMDR therapy changes the way traumatic memories are stored in the brain, allowing individuals to process the trauma and remember the event without reliving it.
While plasticity occurs throughout the lifetime, it is most active in childhood as a part of normal human development. During childhood, the brain is very plastic, and connections between different brain areas change in strength as children have different experiences and develop an understanding of the world. Trauma can negatively affect many areas of a child's brain and put a strain on the sympathetic nervous system from constant activation. However, the brain's neuroplasticity during childhood can help cope with these adverse effects and enable healing from trauma.
Overall, neuroplasticity is a powerful tool that can help individuals recover from trauma by changing their neural pathways and creating new, healthy habits. Therapies such as EMDR can utilise neuroplasticity to support individuals in healing and moving forward from traumatic experiences.

Synaptic pruning
The brain starts to remove synapses that it no longer needs shortly after a period of synaptic growth. This typically occurs around 2 to 3 years of age, when the number of synapses peaks. The process follows the "'use it or lose it' principle, where active synapses are strengthened, and less active synapses are weakened and ultimately pruned. Synaptic pruning is influenced by genes and a person's experiences.
The process of synaptic pruning is important for maintaining efficient brain function as we learn new complex information. Researchers are also investigating the potential link between synaptic pruning and the onset of certain disorders, such as schizophrenia and autism. Some theories suggest that schizophrenia may be associated with "'over-pruning," while autism may be linked to "under-pruning," resulting in an oversupply of synapses in certain brain regions.

Frequently asked questions
Plasticity, or neuroplasticity, refers to the brain's ability to reorganise and rewire its neural connections, allowing it to adapt and function differently. This process can occur in response to learning new skills, environmental changes, recovering from injuries, or adapting to deficits.
Plasticity allows nerve cells to change or adjust. The brain can reorganise pathways, create new connections, and sometimes create new neurons. Functional plasticity refers to the brain's ability to move functions from a damaged area to an undamaged one. Structural plasticity is the brain's ability to change its physical structure as a result of learning.
Plasticity occurs throughout a person's life, but young brains tend to be more sensitive and responsive to experiences. The brain changes a great deal during early development as it grows and organises itself. However, adult brains are still capable of adaptation, and the brain never stops changing in response to learning.
