Plasticity in psychology refers to the brains ability to change and adapt in response to intrinsic or extrinsic stimuli by reorganizing its structure, functions, or connections. It is also known as neuroplasticity or brain plasticity. 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 to as synaptic plasticity. Structural neuroplasticity is the brain’s ability to change its physical structure as a result of learning, involving reshaping individual neurons (nerve cells) . The time windows for plasticity exist during development shape the connections in the brain and its activity, and it is essential for learning and memory processes. Although traditionally associated with changes in childhood, recent research indicates that mature brains continue to show plasticity due to learning. Plasticity allows the brain to cope better with the indirect effects of brain damage resulting from injuries such as a stroke or traumatic brain injury (TBI) . However, when brain damage occurs, these synapses can become activated and open up connections to regions of the brain that are not normally active and take over the neural function that has been lost due to damage.
