query: What is neuroplasticity?
passage: Neuroplasticity
Neuroplasticity, also known as brain plasticity, neuroelasticity, or neural plasticity, is the ability of the brain to change throughout an individual's life, e.g., brain activity associated with a given function can be transferred to a different location, the proportion of grey matter can change, and synapses may strengthen or weaken over time. 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.[1][2][3][4] However, the developing brain exhibits a higher degree of plasticity than the adult brain.[5][6]:30
passage: Activity-dependent plasticity
Activity-dependent plasticity plays a very important role in learning and in the ability of understanding new things. It is responsible for helping to adapt an individual's brain according to the relative amount of usage and functioning. In essence, it is the brain's ability to retain and develop memories based on activity-driven changes of synaptic strength that allow stronger learning of information. It is thought to be the growing and adapting quality of dendritic spines that provide the basis for synaptic plasticity connected to learning and memory. Dendritic spines accomplish this by transforming synaptic input into neuronal output and also by helping to define the relationship between synapses.
