Definition
Regenerate refers to the process of regrowth or renewal of cells, tissues, or organs after damage or injury. In the context of neurons, regeneration refers to their ability to repair and replace damaged or lost parts.
Plasticity refers to the brain's ability to change and adapt throughout life. It allows for learning, memory formation, and recovery from injuries by rerouting neural pathways or forming new connections.
Stem cells: Stem cells are undifferentiated cells that have the potential to develop into different types of specialized cells. They play a crucial role in tissue regeneration and repair.
Central nervous system (CNS): The central nervous system includes the brain and spinal cord. It is responsible for processing information and coordinating responses within the body. Neuron regeneration within the CNS is more limited compared to other areas of the body.
