The brain's remarkable ability to reorganize itself by forming new neural connections and modifying existing ones throughout life, enabling learning, memory, and recovery from injury.

Neural Plasticity

Neural plasticity, also known as neuroplasticity or brain plasticity, represents the brain's fundamental ability to adapt and reorganize itself throughout an individual's lifetime. This dynamic property underlies everything from early development to lifelong learning and recovery from brain injuries.

Core Mechanisms

The brain demonstrates plasticity through several key mechanisms:

Synaptic Plasticity
- Strengthening or weakening of existing synaptic connections
- Formation of new synapses and pruning of unused ones
- Regulation through long-term potentiation and long-term depression
Structural Plasticity
- Physical changes in neural structures
- Growth of new dendrites and axonal branches
- Modification of existing neural circuits

Types of Neural Plasticity

Developmental Plasticity

During early life, the brain exhibits exceptional plasticity, allowing for:

Formation of basic neural architecture
Development of sensory systems
Establishment of critical periods for learning

Experience-Dependent Plasticity

Continues throughout life, enabling:

Learning and Memory
Skill acquisition
Behavioral adaptation
Environmental response

Reactive Plasticity

Occurs in response to:

Brain Injury
Trauma
Disease
Environmental changes
