Neuroplasticity can be broadly defined as the ability of the nervous system to respond to intrinsic and extrinsic stimuli by reorganizing its structure, function and connections; can be described at many levels, from molecular to cellular to systems to behaviour; and can occur during development, in response to the environment, in support of learning, in response to disease, or in relation to therapy. Such plasticity can be viewed as adaptive when associated with a gain in function or as maladaptive when associated with negative consequences such as loss of function or increased injury, points illustrated by animal models and some human studies. Also, adaptive plasticity should be distinguished from compensatory behaviours, which are behaviours that arise from mechanisms different from those operative in the distributed neural networks that typically support behaviour prior to disease onset.

Neuroplasticity is the term used to describe this capacity for creating new neural connections and growing new neurons in response to experience. Neuroplasticity is not just available to us in youth: We now know that it can occur throughout the lifespan.

This source traces the history of the term. In the late 1960s, the term “neuroplasticity” was introduced for morphological changes in neurons of adult brains.

Further Details

Neuroplasticity is the capacity of a brain to change or be modified at cellular or behavioral levels.

Further Details

Brain plasticity or neuroplasticity is the inherent capacity of nerve tissue to form new interneuronal connections or synapses (synaptogenesis) or replace useless, nonfunctional (neurodegeneration) neurons in the brain with new neurons (neurogenesis).

Further Details

Neuroplasticity appears to be an efficient way to recruit the brain’s limited resources. Depending on the context, neural plasticity can: (1) confer no perceptible change in the behavioral output of the brain; (2) lead to changes demonstrated only under special testing conditions (high-demanding task); or (3) cause behavioral changes through takeover of other functional systems. Plasticity is an intrinsic, permanent characteristic of the nervous system, and understanding of normal or abnormal psychologic function necessitates invoking the concept of brain plasticity.

The brain’s capacity to alter its structure and function in reaction to environmental diversity, thus reflecting a capacity that is often referred to as brain plasticity. Although this term is now commonly used in psychology and neuro-science, it is not easily defined and is used to refer to changes at many levels in the nervous system ranging from molecular events, such as changes in gene expression, to behavior.

Further Details

The ability of the brain to develop new neurons and/or new synapses in response to stimulation and learning. Recent research shows that the brain retains its plasticity throughout life, more or less, depending on the person’s state of health, etc. Following injury to the brain, neuroplasticity may allow uninjured areas to take over the processes previously carried out by the injured areas.

Further Details

Neuroplasticity can be defined as brain’s ability to change, remodel and reorganize for purpose of better ability to adapt to new situations. Despite the fact that the concept of neuroplasticity is quite new, it is one of the most important discoveries in neuroscience. “ The fact is that neural networks are not fixed, but occurring and disappearing dynamically throughout our whole life, depending on experiences. While we repeatedly practice one activity such as a sequence of movements or a mathematical problem, neuronal circuits are being formed, leading to better ability to perform the practiced task with less waste of energy. Once we stop practicing a certain activity, the brain will redirect these neuronal circuits by a much known ‘use it or lose it’ principle. Neuroplasticity leads to many different occurrences, such as habituation, sensitization to a certain position, medication tolerance, even recovery following brain injury.

Further Details

Neuroplasticity is a continuous processing allowing short-term, medium-term, and long-term remodeling of the neuronosynaptic organization, with the aim of optimizing the functioning of neural networks during phylogenesis, ontogeny, and physiologic learning, and following brain injury.

Further Details

There are numerous neuroplasticity mechanisms including biochemical, physiological, and structural changes with numerous consequences in behavioral plasticity. Cellular plasticity allows the brain to learn new behaviors, which can in turn alter the brain and further strengthen the behavior. Therefore, plasticity both results from, and entails behavioral changes.

Further Details

Neuroplasticity is the process that adapts the nervous system’s connectivity and structure to changes in the body’s internal and external environment.

Further Details

Neurogenesis continues in adults - The most appealing phenomenon of neuroplasticity appears to be adult neurogenesis, that is the generation of new neurons in adult brains. The “no new neurons” dogma was already challenged almost five decades ago. Using autoradiography with the tritiated DNA nucleoside 3H-thymidine, Altman [27, 28] gained first evidence for the production of glia cells and possibly also of neurons in the brains of young adult rats and adult cats.

The capacity of brain cells to change in response to intrinsic and extrinsic factors.

Further Details

The ability of the brain to form and reorganize synaptic connections, especially in response to learning or experience or following injury.

Further Details

Neuroplasticity, a very loosely defined term that simply means some kind of change in the nervous system. Different researchers define neuroplasticity in different ways, depending on exactly which aspect of brain and behavior they are studying, and the term is so vague that it has become virtually meaningless when used alone and without further explanation of exactly what type of plastic changes are taking place.

Further Details

Neuroplasticity can be defined as the reorganization of the brain’s structure and function in response to intrinsic or environmental challenges.

Further Details

Inclusion of neuron death - In the late 1990s, there were reports that even the stress that an individual experiences can kill neurons in the brain.

Further Details

The adaptive capacity of the central nervous system (plasticity). We will go so far as to say that neural plasticity is the mechanism by which the brain encodes experience and learns new behaviors. It is also the mechanism by which the damaged brain relearns lost behavior in response to rehabilitation.

Further Details

The extraordinary ability of the brain to modify its own structure and function following changes within the body or in the external environment. The large outer layer of the brain, known as the cortex is especially able to make such modifications. Brain plasticity underlies normal brain function such as our ability to learn and modify our behavior. It is strongest during childhood, thus explaining the fast learning abilities of kids, but remains a fundamental and significant lifelong property of the brain. Adult brain plasticity has been clearly implicated as a means for recovery from sensory-motor deprivation, peripheral injury, and brain injury. It has also been implicated in alleviating chronic pain and the development of the ability to use prosthetic devices such as robotic arms for paraplegics, or artificial hearing and seeing devices for the deaf and blind.

The notion that the brain can change in response to experience and training--a convergence that provides a foundation for us as scientitst to go forward in a truly novel and integrative way.

Further Details

“It refers to the physiological changes in the brain that happen as the result of our interactions with our environment. From the time the brain begins to develop in utero until the day we die, the connections among the cells in our brains reorganize in response to our changing needs. This dynamic process allows us to learn from and adapt to different experiences.” – Celeste Campbell (n.d.).

Further Details

Neural plasticity can be defined as the ability of the central nervous system (CNS) to adapt in response to changes in the environment or lesions. This property of the CNS may involve modifications in overall cognitive strategies to successfully cope with new challenges (i.e., attention, behavioral compensation), recruitment of new/different neural networks, or changes in strength of such connections or specific brain areas in charge of carrying out a particular task (i.e., movement, language, vision, hearing).

Further Details

Neuroplasticity is defined as the ability of the nervous system to respond to extrinsic or intrinsic stimuli by a reorganization of its function, structure, or connections. It has a significant functional, but also a therapeutic, role across brain diseases, as well as in health. It can be experience-driven, is time-sensitive, and it is influenced by the environment and internal states, such as motivation and attention.

Further Details

Neuroplasticity enables the brain to repair, modify, and resist damages (6). Neuroplasticity is considered as the capacity of brain to alter at the cellular (neural plasticity) or the behavioral level (behavioral plasticity), which can be either adaptive or incompatible. Brain adaptive plasticity involves efficient redirecting, while incompatible plasticity furthers aphasia symptoms and results in poor recovery due to the brain’s inefficient reprogramming.

Further Details

The manner in which the nervous system can modify its organization and ultimately its function throughout an individual’s lifetime, a property that is often referred to as plasticity. When the nervous system changes, there is often a correlated change in behavior or psychological function. This behavioral change is known by names such as learning, memory, addiction, maturation, and recovery.
