Cellular Neurobiology is the study of the cells in the nervous system, focusing on how they function and communicate. This field examines different types of cells, such as neurons, which transmit signals, and glial cells, which support and protect neurons. Understanding these cells helps scientists learn how the brain and spinal cord work, as well as how they respond to injury or disease. Researchers in cellular neurobiology use various techniques to explore cellular processes, including electrophysiology to measure electrical activity and imaging methods to visualize cells in action. This knowledge is crucial for developing treatments for neurological disorders like Alzheimer's disease and Parkinson's disease.
