Plasticity is a broad concept that can be observed in various contexts, such as physics, biology, and neuroscience. In physics, plasticity refers to the ability of solid materials to undergo permanent deformation, like bending a piece of metal into a new shape. This phenomenon is also influenced by factors like temperature, with most metals exhibiting greater plasticity when hot. In biology, developmental plasticity highlights the impact of the environment on an organism's traits, as seen in the colour variation of certain butterflies. In neuroscience, brain plasticity, or neuroplasticity, showcases the brain's remarkable ability to adapt, change, and reorganise itself in response to stimuli, learning, and injuries. This adaptability is evident in both positive and negative scenarios, ranging from cognitive improvements to behavioural issues. Understanding plasticity in its diverse manifestations provides valuable insights into the inherent flexibility and potential for transformation within materials, organisms, and the human brain.

Neuroplasticity: the brain's ability to adapt and reorganise after damage
Neuroplasticity, also known as neural plasticity or brain plasticity, is the process by which neurons and brain neural networks adapt or change functionality in response to stimuli through reorganisation and growth. This reorganisation can occur after damage to the brain, allowing it to adapt and recover lost functions.
For example, a child who experiences a traumatic brain injury may have to re-learn how to walk and talk. With therapy and rehabilitation, other parts of the brain can take over the functions of the damaged areas, demonstrating the brain's capacity to reroute functions as needed. This is possible due to the brain's ability to form new neural connections and pathways, as well as create new neurons.
Neuroplasticity is also observed in stroke survivors who engage in physical therapy to regain movements they lost due to brain injuries. Through consistent training and practice, they can often recover significant function, as different parts of the brain compensate for the damaged areas.
In addition to recovery from brain injuries, neuroplasticity plays a crucial role in learning and memory. For instance, musicians who play various instruments develop strong and fast neuronal connections, requiring coordination between multiple brain areas. Similarly, physical activities and exercises influence the brain to improve its structure and slow age-related complications. They can promote hippocampal development, improve memory, strengthen synaptic connections, and increase IQ.
While neuroplasticity is essential for recovery and learning, it can also be negatively impacted by certain factors. For example, substance use, disease, trauma, and medical conditions such as epilepsy or cerebral palsy can hinder brain plasticity.

Physical activity: exercise boosts brain plasticity and promotes neuron survival
Neuroplasticity, also known as neural plasticity or brain plasticity, is the process by which neurons and brain neural networks adapt or change functionality in response to stimuli through reorganisation and growth. The brain's plasticity refers to its ability to alter its structure and function, which is fundamental for learning, memory, and cognitive processing.
Physical exercise (PE) has been shown to have a positive impact on brain plasticity and neuron survival. For example, PE has been found to increase cell signalling and neuronal growth, leading to improved cognitive functioning and psychological well-being. Studies have also shown that PE can increase the plasticity of the hippocampus, promoting changes in serotonin metabolism and synaptic plasticity. This can help in treating depression and anxiety caused by stress or neurodegenerative diseases.
In addition to its mental health benefits, PE has been found to have positive effects on brain health and the treatment of neurodegenerative diseases. For instance, voluntary running exercise has been shown to enhance BDNF expression in the dorsal striatum of PD model mice, leading to a notable increase in extracellular dopamine concentrations. Exercise has also been found to increase chemicals that promote neuron survival and growth, such as brain-derived neurotrophic factor (BDNF).
Furthermore, PE can improve learning and memory. For example, a study found that treadmill exercise for 12 weeks as part of an AD intervention program increased mitochondrial proteostasis in mice, leading to improved performance in a water maze test. Another study found that 4 weeks of sustained platform-running exercise positively impacted the plasticity of motor cortex function in rats with PD, ameliorating abnormal neural activity in the primary motor cortex (M1) region.
Overall, physical exercise boosts brain plasticity and promotes neuron survival, leading to improved cognitive functioning, mental health, and brain health.

Learning new skills: structural plasticity allows the brain to change its physical structure
The human brain is capable of remarkable plasticity, or neuroplasticity, allowing it to adapt and change in response to experiences, learning processes, behaviours, thoughts, and even injuries. Structural plasticity refers specifically to the brain's ability to change its physical structure as a result of learning new skills.
Neuroplasticity is the process by which neurons and neural networks adapt or change functionality, reorganizing and growing in response to stimuli. This can occur at both functional and structural levels, and the brain can even create new neurons. This process is essential for recovery from brain injuries, as it allows the brain to form new neural connections and pathways, enabling individuals to regain lost functions. For example, a child who has experienced a traumatic brain injury may need to re-learn how to walk and talk. With therapy and rehabilitation, other parts of the brain can take over these functions, demonstrating the brain's capacity for structural plasticity.
The brain's ability to change its physical structure through structural plasticity is also evident in individuals who undergo intensive brain training programs. For instance, an individual with developmental disabilities may, after such a program, be able to read with full comprehension for the first time in years. Their cognitive testing scores may improve, and they may show signs of emotional development, such as remorse for past actions. This showcases the brain's ability to change and adapt through structural plasticity, allowing for the development of new skills and behaviours.
Physical activities and exercises also contribute significantly to neuroplasticity. For instance, musicians who play various instruments develop strong and fast neuronal connections, as well as high levels of coordination. Similarly, physical exercises such as aerobics, running, hiking, and swimming can influence brain structure, improving hippocampal development, auditory memory, and synaptic connections, as well as increasing IQ. These exercises also promote the growth of neurons by increasing the production of chemicals such as brain-derived neurotrophic factor (BDNF).
Overall, structural plasticity allows the brain to change its physical structure in response to learning new skills. This process involves reshaping neurons and neural pathways, as well as the growth of new neurons, enabling the brain to adapt and develop in response to new experiences and information.

Musicianship: learning music and playing instruments improves neuroplasticity
Neuroplasticity, also known as neural plasticity or brain plasticity, is the process by which neurons and brain neural networks adapt or change functionality in response to stimuli through reorganisation and growth. Neuroscientists have asserted that the human brain can reorganise or rewire itself after going through certain experiences, learning processes, activities, behaviours, thoughts, pain, or even traumatic brain injuries.
Learning music and playing instruments is one such activity that improves neuroplasticity. Musical training is considered a useful framework for researching training-induced neuroplasticity. Cross-sectional studies have identified structural and functional differences between the brains of musicians and non-musicians, especially in regions related to motor control and auditory processing. Learning to play a musical instrument is a complex task that integrates multiple sensory modalities and higher-order cognitive functions. The skills underlying the ability to learn a piece of music resemble those involved in memorising a poem or a piece of prose. Several investigations have shown that structural and functional cerebral neuroplastic processes emerge as a result of long-term musical training, which in turn may produce cognitive differences between musicians and non-musicians.
Music education can help to prevent various forms of neurological diseases, such as dementia. It also strengthens the body and helps to maintain coordination and motor skills. Playing music also has a positive effect on stress, as one has to isolate their focus. Unlike other brain exercises, music is a consistently rewarding pursuit. Every time one improves, they benefit from the neurological rewards and can also enjoy their new skills right away.
The brain’s ability to develop is called neuroplasticity, and one way of retaining that plasticity is by playing music. Every time something new is learned, the brain transforms. When a new song is learned on the guitar or sight-reading skills are improved, the neurons in the brain change. New brain cells are developed, and connections between them are formed. This means that the brain is never fully grown and will continue to develop as new skills are learned and new experiences are gained.
Physical activities and exercises like aerobics, running, hiking, and swimming have also contributed significantly to neuroplasticity. These exercises influence someone’s brain to improve its structure and slow age-related complications. Physical activities can promote hippocampal development, improve auditory memory, strengthen synaptic connections, increase IQ, increase supply, and promote other neuroplasticity functions, even as we age.

Plastic deformation: the ability of a solid material to undergo permanent deformation
In physics and materials science, plasticity, or plastic deformation, is defined as the ability of a solid material to undergo irreversible changes in shape in response to applied forces. This phenomenon is observed in various materials, particularly metals, soils, rocks, concrete, and foams.
Metals, for instance, exhibit plasticity when heated, allowing them to be shaped. Lead, for example, demonstrates sufficient plasticity at room temperature, while cast iron lacks the necessary plasticity for forging operations even when heated. The plasticity of metals is often attributed to dislocations within their crystal structure, which are defects that allow planes of atoms to slip past each other, resulting in a permanent change of shape.
Soils, particularly clays, also exhibit significant plasticity due to the rearrangement of adjacent grain clusters. Rocks and concrete undergo plastic deformation through the formation of microcracks and sliding motions relative to these cracks. At high temperatures and pressures, the motion of dislocations within individual grains can further influence plastic behaviour.
In engineering, the transition from elastic behaviour to plastic behaviour is known as yielding. Perfect plasticity is characterised by irreversible deformation without any increase in stresses or loads. However, materials that have been hardened by prior deformation may require higher stresses to achieve further deformation.
Additionally, microplasticity is observed in metals when stress values place the metal in the global elastic domain while local regions exhibit plastic behaviour. Amorphous materials, such as polymers, can undergo plastic deformation despite lacking a long-range order due to the presence of free volume or wasted space. This wasted space allows for the formation of fibrils within regions of high hydrostatic stress, resulting in a hazy appearance known as crazing.

Frequently asked questions
Plasticity is the ability of a material or organism to change form or function in response to external factors or experiences. In physics, plasticity refers to the ability of a solid material to undergo permanent deformation, or a non-reversible change of shape, in response to applied forces. In biology, plasticity refers to the ability of an organism to change and adapt in response to its environment, also known as developmental plasticity.
Some examples of plasticity in physics include the bending or pounding of metal into a new shape, the stretching of plastic wrap, and the behaviour of ductile metals under tensile loading.
An example of developmental plasticity in biology is the "squinting bush brown butterfly" (Bicyclus anynana) from eastern Africa, which can vary its wing colour depending on the season. This plasticity allows the butterfly to survive in both warm and cool seasons.
Neuroplasticity refers to the brain's ability to change and grow in response to its environment, learning processes, experiences, behaviours, and injuries. An example of neuroplasticity is demonstrated through brain training and rehabilitation programs, which can help individuals with cognitive and behavioural dysfunction re-integrate into society and improve their cognitive functioning.
