«Is this LA?»
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,   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.

Brain Structural Plasticity: From Adult Neurogenesis to Immature Neurons
Adult neurogenesis and functional plasticity in neuronal circuits | Nature Reviews Neuroscience
The massive amount of connections between neurons cannot be simply inscribed in genetic code, as the former severely outnumbers the latter. Amongst others, the genome is assigned to the important task of encoding the variety of nerve cell forms and different neurotransmitters, but genes cannot specify the exact connections between individual neurons. What is more, the brain also has to remain flexible in a more mature state, that is, in adulthood, and retain its ability to change existing connections and structure as a reaction to altering environmental circumstances. It is this ability of the brain to react to changes in experience in adulthood that we are interested in in this part of the project. There is accumulating evidence for the occurrence of such plastic changes in the adult human brain structure. So far, relatively little is known about the mechanisms underlying these observed alterations and their time course. In this project we are using different behavioral paradigms to extend the evidence on brain plasticity, with a focus on investigating the timing of plastic changes while they accompany behavioral skill acquisition.

Plasticity in Adults
Language: English Spanish French. The adult brain has long been considered stable and unchanging, except for the inevitable decline that occurs with aqinq. This view is now being challenged with clear evidence that structural changes occur in the brain throughout life, including the generation of new neurons and other brain cells, and connections between and among neurons. What is as remarkable is that the changes that occur in the adult brain are influenced by the behaviors an individual engages in, as well as the environment in which an individual lives, works, and plays.

Brain structural plasticity is an extraordinary tool that allows the mature brain to adapt to environmental changes, to learn, to repair itself after lesions or disease, and to slow aging. Yet, this road does not seem a straight one, since mutable dogmas, conflicting results and conflicting interpretations continue to warm the field. As a result, after more than 10, papers published on AN, we still do not know its time course, rate or features with respect to other kinds of structural plasticity in our brain.
