What is neuroplasticity? In a nutshell, neuroplasticity is the ability of the brain to change its structure and function in response to daily experiences. This means that our brains are not static; they are constantly changing in response to the world around us.
This has some pretty amazing implications for our lives! In this beginner's guide, we will discuss neuroplasticity in more detail and explore some of the ways that it can benefit us.
A brief history of neuroplasticity
The term “neuroplasticity” was first introduced by Polish neurologist Jerzy Konorski in 1948. The word evolved from the term plasticity which was used by William James in 1890 to describe the brain's ability to change in response to experience. Konorski 's believed that this plasticity occurs at all levels of the nervous system, from individual neurons to complex neural networks.
Neuroplasticity, also known as brain plasticity, was initially met with skepticism by the scientific community. It was not until the late 1970s and early 1980s that neuroscientists began to take neuroplasticity seriously as a real phenomenon. One of the most famous brain research on neuroplasticity was conducted by neuroscientist Michael Merzenich in the 1980s. Merzenich trained monkeys to use their hands to perform a task. He then recorded the activity of neurons in the monkeys' brains. He found that when the monkeys were first learning the task, there was a lot of activity in their brains. However, as they became more skilled at the task, the brain activity decreased. This showed that as we learn a new skill, the brain becomes more efficient at performing that task.
In recent years, neuroplasticity has emerged as a key factor in recovery from brain injury. One of the most well-known examples of neuroplasticity is the ability of the brain to recover from a brain injury. When an area of the brain is damaged, brain plasticity allows other regions to take over its functions. This process of “neural compensation” helps to minimize the impact of brain damage and improve long-term outcomes.
Neuroscientists are now able to understand better the ability of the brain to reorganize itself in response to injury, providing hope for people who have suffered a stroke or other forms of neurological damage.
Neuroplasticity also plays a role in learning and memory. Every time we learn something new, our brains change in response. This process is known as synaptic plasticity, and it helps to explain how we are able to remember information and skills that we have learned. In addition, neuroplasticity is thought to underlie some forms of mental disorders, such as depression and anxiety. By understanding how the brain changes in response to experience, we can develop better treatments for these conditions.
The theory and principles of neuroplasticity
The theory of neuroplasticity states that the brain is capable of making
changes and adaptations throughout life in response to experience. This process of brain plasticity occurs at all levels, from individual neurons to large-scale cortical networks.
7 Facts about neuroplasticity
1. Neurons are plastic
They change and adapt in response to experience. This is the most fundamental principle of neuroplasticity. Neurons are the basic building blocks of the brain, and they are constantly changing in response to our environment and experiences.
Neuroscientists used to believe that neurons were static; once they matured, they could not change. However, we now know that this is not the case.
2. Glial cells support neuronal plasticity
Although most people are familiar with neurons, they are not the only type of cells that make up the nervous system. Glial cells play an equally important role in neural function, and recent research has shown that they may be even more important than previously thought.
One of the main functions of glial cells is to provide support and protection for neurons. However, they also play a role in neuroplasticity. Without glial cells, neural connections would be much less stable, and the brain would be less able to learn and remember new information.
3. Connections between neurons are constantly changing
When we learn something new, the synapses between the neurons involved in that task become stronger. This makes it easier for those neurons to fire together in the future, and it is how we store memories.
Conversely, when we stop using a particular set of neurons, the synapses between them become weaker. This process is known as synaptic pruning, and it helps to keep the brain efficient by getting rid of unnecessary connections.
Depending on our daily habits and experiences, our brain will constantly be creating new neural connections, reorganizing existing ones, or pruning away unused ones.
4. Experience alters neural connections
The connections between neurons, known as synapses, are constantly changing in response to our daily experiences. This process is called synaptic plasticity, and it is the basis for learning and memory.
When we learn something new, the neurons involved in that task fire together and form a new connection. This connection becomes stronger with repeated use.
The video below is a great example of neuroplasticity in action. First, your brain will resist, but with consistency and the right mindset, a new skill can be developed. The same thing can be said about our thoughts and emotions. With consistency and the right mindset, you can reprogram your subconscious mind for success.
5. Neural connections can be strengthened or weakened
As we go through life, our brains form trillions of neural connections. However, the strength of these connections can vary depending on several factors. For example, exposure to new experiences is known to strengthen neural pathways, while chronic stress can weaken them. Additionally, certain medications and lifestyle choices (such as exercise) can also impact the strength of our synaptic connections.
The most common factors that negatively affect neuroplasticity are:
- Chronic stress
- Aging
- Traumatic brain injury (TBI)
- Substance abuse
- Sleep deprivation
- Unhealthy diet
Fortunately, neuroplasticity is a two-way street. Just as negative experiences or habits can weaken neural connections, positive experiences can strengthen them. In other words, we have the power to change our brains for the better. Some of the most effective ways to improve neuroplasticity are:
- Regular exercise
- Engaging in new experiences and learning new things
- Meditation and mindfulness practices
- Getting a Good Night’s Sleep (7 to 8 hrs every night)
- Eating a healthy diet
- Reducing stress levels
- Protect your brain from injuries
All of these activities help to reduce stress, increase blood flow to the brain, and promote the growth of new neural connections. When it comes to neuroplasticity, we really are what we eat, think, and do.
Therefore, it is important to be mindful of both the things that can weaken our neural connections as well as the things that can strengthen them. By taking care of our mind and body, we can help ensure that our neural connections remain strong and healthy.
6. As a whole, the brain is constantly adapting
The human brain is an incredible thing. It's able to process a staggering amount of information and can adapt to changes in the environment remarkably quickly. One of the most famous examples of brain plasticity is the case of Phineas Gage, who survived an accident in which a metal rod was driven through his skull. Although doctors expected him to die or be left with severe brain damage, he made a full recovery and was even able to return to work. While his personality did change somewhat as a result of the accident, it just goes to show how incredibly resilient the human brain can be.
7. Neuroplasticity occurs throughout our lifespan
From the moment our central nervous system is formed, until the day we die, our brains are constantly changing. However, the rate at which neuroplasticity occurs varies depending on our age. For example, babies' brains are growing and changing at an incredible rate, while an adult brain changes much more slowly.
In addition, the process that occurs is different throughout a person's lifetime. For example, during childhood and adolescence, the brain is mainly concerned with making connections and consolidating information. In adulthood, the focus shifts to maintaining those connections and preventing them from weakening. And in older age, the focus is on compensating for any loss of neural connections that may have occurred over the years.
10 principles of neuroplasticity
Jeffrey Kleim and Theresa Jones, two pioneers in the field of neuroplasticity, have identified ten principles of neuroplasticity that are important to understand in order to maximize its potential. These principles are:
1. User It or Lose It
The brain changes in response to the demands placed on it. If you don't use a particular skill, the neural pathways associated with that skill will weaken.
2. Use It and Improve It
The more you use a particular skill, the better you'll become at it. This is because repeated practice strengthens the neural pathways associated with that skill. The brain is also good at finding new ways to do things, so if you can't do something the usual way, don't be afraid to try a new approach.
3. Specificity
The brain changes in response to specific types of stimuli. For example, motor skill acquisition will use different neural pathways than visual mapping and recognition.
4. Repetition matters
The more often a particular skill is used, the greater the firing of the neurons and changes in brain structure and function.
5. Intensity matters
The more intense the practice, the greater the electrical impulses in the brain which strengthen synaptic connections.
6. Time matters
Neural plasticity doesn't happen in a single event. Instead, it is the result of a complex chain reaction involving changes at the molecular, cellular, and physiological levels.
7. Salience Matters
The more salient the task (i.e., the more important or interesting it is to you), the greater the changes in brain structure and function.
8. Age Matters
Although the brain is most plastic during childhood and adolescence, it can remain plastic throughout the lifespan. There is no limit to neuroplasticity: The brain can continue to change and adapt at any age as long as you have a mindset for learning and expansion.
9. Transference
The skills you learn in one area can be transferred to other areas. For example, if you learn how to play the piano, you may also find it easier to learn how to play the guitar.
10. Interference
Neuroplasticity can make it more challenging to make behavioral changes. This is because the brain will often revert to its original state to protect a given neural circuitry. Brain research has shown that some types of noninvasive cortical stimulation applied during or shortly before a new behavioral experience can help to reduce this interference.
By understanding these principles, we can begin to understand how brain plasticity happens in response to experience, and how we can use this knowledge to improve our lives.
Types of Neuroplasticity
There are two types of neuroplasticity. Structural neuroplasticity, which is the most well-known, is when there are changes in the brain's physical structure, such as the growth of new neurons or changes in the way existing neurons connect to each other.
And functional neuroplasticity, which is less well-known but just as important, is when there are changes in the way neurons fire and communicate with each other. These changes can happen very quickly, and they don't necessarily result in any changes to the brain's physical structure.
Both types of neuroplasticity are important for learning and memory, and both types can occur in response to experience.
Neuroplasticity and Psychology
Neuroplasticity is a powerful force that can shape our thoughts, emotions, and behavior. And it doesn't just happen in childhood; it occurs throughout our lifespan. Researchers are only just beginning to understand the full implications of neuroplasticity. But what we do know is that it has the potential to change the way we think about psychological disorders and treatment.
For example, if a person suffering from depression can rewire their brain to form new, positive connections, then they may be able to find relief from their symptoms. The same goes for other disorders like anxiety, OCD, and PTSD. Understanding neuroplasticity can help us develop more effective treatments for mental illness and unlock new ways to improve our mental health.
Neuroplasticity vs. Neurogenesis
Neuroplasticity and neurogenesis are two key processes that occur throughout our lifespan. Neuroplasticity refers to the brain's ability to adapt and change in response to experience. This process starts in infancy, when the brain is growing and developing at a rapid pace, and continues into adulthood.
Neurogenesis, on the other hand, is the process of creating new nerve cells. This occurs throughout our lifespan but is most active during infancy and childhood. While both neuroplasticity and neurogenesis are important for healthy brain function, they serve different purposes. Neuroplasticity helps us to learn new information and make new connections, while neurogenesis helps to replace damaged or lost nerve cells. As we age, neurogenesis slows down and neuroplasticity becomes more important for maintaining cognitive function.
Donald Hebb, a Canadian neuropsychologist, famously said that "neurons that fire together, wire together." This simple statement sums up the process of neuroplasticity perfectly. When we learn something new or have an experience, the neurons involved in that task fire together and form a new connection. The more we repeat the experience, the stronger that connection becomes.

Frequently Asked Questions
What are some everyday examples of neuroplasticity?
Some everyday examples of neuroplasticity include learning a new skill, recovering from a stroke, and developing chronic pain. When we learn a new skill, the brain forms new neural connections in order to store this information. Stroke survivors often undergo intense rehabilitation in order to relearn lost skills; this process also relies on neuroplasticity, as the brain forms new connections to circumvent damaged areas.
Chronic pain, on the other hand, is an example of negative neuroplasticity, where repeated exposure to pain leads the brain to amplify pain signals. However, even in this case, neuroplasticity offers hope, as research suggests that mindfulness-based therapies may help to rewire the brain and reduce chronic pain.
What can influence brain development?
There are a number of factors that can influence brain development throughout a person's lifespan. For example, early experiences can play a role in sculpting the developing brain. Additionally, nutrition is critical for proper brain development, especially during key periods such as infancy and adolescence. Additionally, exposure to toxins or stress can also impact brain development.
Finally, genetics also plays a role in brain development. Certain genetic conditions can lead to delays or impairments in brain development. However, it is important to remember that the brain is resilient and has the ability to adapt and change throughout a person's lifetime. Therefore, even if there are some challenges during early brain development, it is possible for the brain to continue to develop and grow in new and wonderful ways.
What is a Traumatic Brain Injury?
A Traumatic Brain Injury (TBI), also known as brain trauma, happens when a bump, blow, or jolt to the head causes damage to the brain. Every year, millions of people in the United States experience some form of TBI. However, not all TBIs are the same. Some people may only experience a brief change in mental status or consciousness, while others may suffer from long-term impairments.
The severity of a TBI can range from mild (a concussion) to severe (an extended period of unconsciousness or amnesia after the injury). In most cases, TBIs are caused by blunt force trauma, such as a car accident or a fall. However, they can also be caused by penetrating injuries, such as a gunshot wound. TBIs can result in a wide range of cognitive, physical and emotional symptoms that can last for days, weeks, months or even years. In some cases, a TBI can lead to permanent disability or even death.
How to treat traumatic brain injuries?
While there is no one-size-fits-all treatment for TBI, there are certain measures that can be taken to improve the chances of a successful recovery. Prompt medical attention is crucial for minimizing the risk of long-term damage, and patients should be monitored closely for any sign of worsening symptoms. In some cases, surgery may be necessary to remove or repair damaged tissue. Rehabilitative therapy can also play a vital role in aiding recovery and helping patients regain as much independence as possible. With the right care and support, people with TBI can often go on to lead full and fulfilling lives.
What is the cerebral cortex?
The cerebral cortex is the outermost layer of the brain and plays a vital role in higher-level cognition, including functions such as processing sensory information, generating motor commands, and governing complex thought processes. The cortex is divided into four lobes - the frontal, temporal, parietal, and occipital lobes - each of which is responsible for different kinds of processing.
For example, the frontal lobe is involved in planning and decision-making, while the temporal lobe is important for language and memory. The cortex continues to develop throughout childhood and adolescence, reaching full maturity around the age of 25. After this point, the cortex begins to decline in function, leading to a deterioration in cognitive abilities in old age. Consequently, the lifespan of the cortex has a direct impact on an individual's cognitive abilities throughout their lifetime.
What are the different brain regions?
There are four main regions of the brain: the cerebrum, the cerebellum, the brainstem, and the diencephalon. Each region has a distinct set of functions, and all four regions are necessary for survival.
The cerebrum is the largest region of the brain, and it is responsible for higher-level functions such as sensory perception, motor control, and cognitive processing. The cerebrum makes up approximately 85% of the brain’s mass.
The cerebellum is located beneath the cerebrum, and it is responsible for coordination and balance. It also plays a role in learning and memory. The cerebellum makes up approximately 10% of the brain’s mass.
The brainstem is located at the base of the brain, and it controls essential functions such as respiration and heartbeat. The brainstem also contains important centers for arousal, attention, and emotion. The brainstem makes up approximately 5% of the brain’s mass.
The diencephalon is located between the brainstem and the cerebrum. It contains important structures such as the thalamus and hypothalamus. The diencephalon plays a role in sensory processing, motivation, and Sleep/wake cycles. The diencephalon makes up approximately 2% of the brain’s mass.
What is the definition of cognitive function?
Cognitive function is often described as the ability to think, remember, and learn. However, cognitive function is not a single, overarching ability. Rather, it is made up of many different abilities that work together to allow us to process information and interact with the world around us. These abilities include attention, executive function, working memory, and processing speed.
While cognitive function can decline with age, there are still many things that people can do to keep their minds sharp throughout their lifespan. For example, staying physically active, eating a healthy diet, and getting enough sleep can all help to support cognitive function. There are also many activities that can help to keep the mind active, such as doing crossword puzzles or learning a new language.
By definition, then, cognitive function is an essential part of our daily lives. It allows us to interact with our environment and make sense of the world around us.
What are the different areas of the brain?
The brain is divided into different areas that control various functions. These areas can be further divided into two categories: the central nervous system and the peripheral nervous system. The central nervous system includes the brain and the spinal cord, while the peripheral nervous system consists of the nerves that extend from the central nervous system to the rest of the body. Each area of the brain is responsible for a specific function, and damage to a certain area can result in difficulty with that particular function.
For example, the frontal lobe is responsible for executive functions such as planning and decision making, while the temporal lobe is involved in processing auditory information. Although the specific functions of each area are still being studied, researchers have made significant progress in understanding how different areas of the brain work together to control our thoughts, emotions, and behaviours. A better understanding of these functions can help us to improve our lifespan and quality of life.
What is the difference between neuroplasticity and brain plasticity?
Neuroplasticity and brain plasticity are often used interchangeably, but there is actually a subtle difference between the two terms. Neuroplasticity refers to the brain's ability to change and adapt throughout one's lifespan. This includes everything from making new connections between neurons to reforming entire neural networks in response to new experiences.
Brain plasticity, on the other hand, is a bit more specific and refers to the brain's ability to physically change in response to environmental stimuli. This can include changes in the structure and function of neurons as well as the formation of new synaptic connections. So, while neuroplasticity is a general term that encompasses all forms of brain changes, brain plasticity refers specifically to the brain's physical changes.
What is the difference between neurons and brain cells?
Neurons are cells that transmit electrical impulses and are the basic unit of the nervous system. Human brain cells, on the other hand, refer to all the cells that make up the brain, including neurons. While both types of cells are important for brain function, neurons have a few key features that set them apart from other brain cells.
One major difference is lifespan: neurons generally live much longer than other types of brain cells. This is likely due to their role in sending electrical impulses, which requires them to be more sturdy and resistant to damage.
Another key difference is that neurons can communicate with each other directly, while other brain cells must communicate indirectly through chemical signals. This allows neurons to respond quickly to changes in the environment and ensures that the brain can function properly.
What is brain plasticity?
Brain plasticity, also known as neuroplasticity, is the brain's ability to change and adapt throughout a person's lifespan. This flexibility is essential for learning and memory, and it allows the brain to recover from injuries and illnesses. Brain plasticity occurs at all levels of the nervous system, from neurons to neural networks. It is thought that brain plasticity is mediated by changes in gene expression, synaptic strength, and neuronal structure. The concept of brain plasticity has revolutionized our understanding of the brain, and it has led to new treatments for conditions such as stroke and Alzheimer's disease.
What are neurons?
Neurons are cells that transmit information throughout the body. They are electrically excitable and release chemicals called neurotransmitters in order to communicate with other cells. The lifespan of a neuron is typically long, lasting anywhere from a few months to the entire lifetime of an individual. However, neurons can be injured or killed by a variety of factors, including disease, trauma, and poisoning. When this happens, the affected individual may experience a loss of sensation or muscle control. In severe cases, death may occur. Therefore, it is important to understand how neurons work in order to protect them from harm.
What is neural plasticity?
Neural plasticity is the brain's ability to change and adapt throughout a person's lifespan. This includes both the growth of new synaptic connections and the strengthening of existing ones. Neural plasticity is thought to be one of the key mechanisms underlying learning and memory. It also plays an important role in recovery from brain injuries, as damaged neurons can often rewire themselves around healthy ones.
Neural plasticity declines with age, but recent research has shown that it can be maintained through activities like exercise and meditation. As science continues to unlock the secrets of the brain, we are sure to learn even more about the amazing potential of neural plasticity.
What is brain derived neurotrophic factor?
Brain derived neurotrophic factor (BDNF) is a protein that is essential for the growth, development, and maintenance of neurons. BDNF is produced in the brain and plays a role in neuroplasticity, which is the ability of the brain to adapt and change in response to experience. Studies in both animals and humans have shown that BDNF levels decline with age, and this may contribute to age-related cognitive decline.
Additionally, BDNF has been shown to play a role in lifespan and healthspan. Low levels of BDNF have been linked to increased risk of neurodegenerative diseases such as Alzheimer's disease, Parkinson's disease, and Huntington's disease. Furthermore, BDNF has been shown to promote healthy aging by protecting neurons from damage and reducing inflammation.
