Brain Plasticity and Functional Recovery

The brain was once thought to be a fixed, unchanging organ — "hardwired" from early childhood. Modern neuroscience has overturned this view. The brain is remarkably plastic — it can change its structure and function in response to experience, learning, and injury throughout the lifespan. This property, known as neuroplasticity, has profound implications for understanding learning, memory, rehabilitation, and recovery after brain damage.

Key Definition: Neuroplasticity (brain plasticity) is the brain's ability to change and adapt its structure and function in response to experience, learning, or injury. This includes the formation of new synaptic connections, the strengthening or weakening of existing connections, and, in some cases, the growth of new neurons.

Mechanisms of Neuroplasticity

Synaptic Plasticity

The most common form of neuroplasticity involves changes at the synaptic level:
