Alessandro Sale, Anthony J. Brain plasticity can be defined as the capacity of cerebral neurons and neural circuits to change, structurally and functionally, in response to experience. This fundamental property is essential for maturation of sensory functions during development, for the adaptability of our behaviour to the environment through learning and memory processes and for brain repair in response to disease and trauma.

Neuroplasticity — or brain plasticity — is the ability of the brain to modify its connections or re-wire itself. Without this ability, any brain, not just the human brain, would be unable to develop from infancy through to adulthood or recover from brain injury. What makes the brain special is that, unlike a computer, it processes sensory and motor signals in parallel.


Brain plasticity, also known as neuroplasticity, is a term that refers to the brain's ability to change and adapt as a result of experience. When people say that the brain possesses plasticity, they are not suggesting that the brain is similar to plastic. Neuro refers to neurons , the nerve cells that are the building blocks of the brain and nervous system, and plasticity refers to the brain's malleability. The human brain is composed of approximately 86 billion neurons. Early researchers believed that neurogenesis , or the creation of new neurons , stopped shortly after birth.

Neuroplasticity in children

Neuroplasticity , also known as neural plasticity , or brain plasticity , is the ability of neural networks in the brain to change through growth and reorganization. These changes range from individual neuron pathways making new connections, to systematic adjustments like cortical remapping. Examples of neuroplasticity include circuit and network changes that result from learning a new ability, environmental influences, practice, and psychological stress. Neuroplasticity was once thought by neuroscientists to manifest only during childhood, [7] [8] but research in the latter half of the 20th century showed that many aspects of the brain can be altered or are "plastic" even through adulthood. The term "plasticity" was first applied to behavior in by William James in The Principles of Psychology. In , Italian anatomist Michele Vicenzo Malacarne described experiments in which he paired animals, trained one of the pair extensively for years, and then dissected both.

Neural plasticity, also known as neuroplasticity or brain plasticity, can be defined as the ability of the nervous system to change its activity in response to intrinsic or extrinsic stimuli by reorganizing its structure, functions, or connections. A fundamental property of neurons is their ability to modify the strength and efficacy of synaptic transmission through a diverse number of activity-dependent mechanisms, typically referred as synaptic plasticity. Research in the past century has showed that neural plasticity is a fundamental property of nervous systems in species from insects to humans. Indeed, studies into synaptic plasticity have not only been an important driving force in neuroscience research but they are also contributing to the well-being of our societies as this phenomenon is involved in learning and memory, brain development and homeostasis, sensorial training, and recovery from brain lesions.

Research in the field of neurosciences and genetics has given us great insight into the understanding of learning and behavior and changes in the brain in resonse to experience. It is seen that brain is dynamically changing throughout life and is capable of tearing at any time. Critical periods of neuroplasticity for various streams of development are also beter understood. Technological advances in non invasive imaging techniques and advances in moleculoar genetics have helped us understand the basis of many developmental disorders which may help in planning effective intervention strategies.

Brain Plasticity and Behavior

Early experiences affect the development of brain architecture , which provides the foundation for all future learning, behavior, and health. Just as a weak foundation compromises the quality and strength of a house, adverse experiences early in life can impair brain architecture, with negative effects lasting into adulthood. Brains are built over time, from the bottom up. The basic architecture of the brain is constructed through an ongoing process that begins before birth and continues into adulthood. Simpler neural connections and skills form first, followed by more complex circuits and skills. Brain architecture is comprised of billions of connections between individual neurons across different areas of the brain. These connections enable lightning-fast communication among neurons that specialize in different kinds of brain functions.

Although the brain was once seen as a rather static organ, it is now clear that the organization of brain circuitry is constantly changing as a function of experience. These changes are referred to as brain plasticity, and they are associated with functional changes that include phenomena such as memory, addiction, and recovery of function. Recent research has shown that brain plasticity and behavior can be influenced by a myriad of factors, including both pre- and postnatal experience, drugs, hormones, maturation, aging, diet, disease, and stress. Understanding how these factors influence brain organization and function is important not only for understanding both normal and abnormal behavior, but also for designing treatments for behavioral and psychological disorders ranging from addiction to stroke. The capacity to change is a fundamental characteristic of nervous systems and can be seen in even the simplest of organisms, such as the tiny worm C. 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.

Neural Plasticity

В феврале того года, когда Энсею исполнилось двенадцать, его приемным родителям позвонили из токийской фирмы, производящей компьютеры, и предложили их сыну-калеке принять участие в испытаниях новой клавиатуры, которую фирма сконструировала для детей с физическими недостатками. Родители согласились. Хотя Энсей Танкадо никогда прежде не видел компьютера, он как будто инстинктивно знал, как с ним обращаться. Компьютер открыл перед ним мир, о существовании которого он даже не подозревал, и вскоре заполнил всю его жизнь. Повзрослев, он начал давать компьютерные уроки, зарабатывать деньги и в конце концов получил стипендию для учебы в Университете Досися. Вскоре слава о фугуся-кисай, гениальном калеке, облетела Токио. Со временем Танкадо прочитал о Пёрл-Харборе и военных преступлениях японцев.

The Impact of Studying Brain Plasticity

Он был гораздо сильнее, и ему легче было бы подталкивать ее вверх, тем более что площадка подсвечивалась мерцанием мониторов в кабинете Стратмора. Но если она окажется впереди, он подставит Стратмору спину. Волоча Сьюзан за собой, он использовал ее как живой щит.

 Я сейчас ее убью. Сзади щелкнул взведенный курок беретты. - Отпусти ее, - раздался ровный, холодный голос Стратмора. - Коммандер! - из последних сил позвала Сьюзан. Хейл развернул Сьюзан в ту сторону, откуда слышался голос Стратмора.

 В Севилью - по делам? - настаивал Ролдан. Ясно, конечно, что это никакой не полицейский, это Клиент с большой буквы.  - Дайте мне угадать: наш номер вам дал приятель.

Беккер вытащил из кармана купюру в тысячу песет и сунул панку в руку. - Премного благодарен, приятель! - крикнул тот ему вслед.  - Увидишь Меган, передавай от меня привет! - Но Беккер уже исчез.

Смит бросил взгляд через плечо. - Сэр… видите ли, он у. - Что значит у вас? - крикнул директор.

Ей казалось, что она слышит его голос, зовущий ее, заставляющий спасаться бегством, но куда ей бежать. Шифровалка превратилась в наглухо закрытую гробницу. Но это теперь не имело никакого значения, мысль о смерти ее не пугала. Смерть остановит боль.

Он сам был своим партнером.
