How is a neuroscientist like and different from a brain surgeon?

A neuroscientist studies the brain and nervous system through research, focusing on understanding their functions, diseases, and potential treatments. In contrast, a brain surgeon, or neurosurgeon, applies medical knowledge to perform surgical procedures on the brain and spinal cord to treat conditions such as tumors or injuries. While both professionals contribute to advancements in neuroscience and patient care, their roles differ significantly: one focuses on research and theory, while the other is involved in practical, hands-on medical interventions.
