Neuroregeneration is the process by which damaged or lost neurons in the nervous system are replaced or repaired. This area of research focuses on understanding how the brain and spinal cord can regenerate or repair themselves after injury, disease, or aging. Researchers in this field study various strategies and techniques to promote neuroregeneration, including stem cell therapy, gene therapy, and pharmacological interventions. The ultimate goal of neuroregeneration research is to develop new treatments and therapies for neurological disorders and injuries.
