The nervous system is a complex network of cells including neurons and glial cells that transmit signals throughout the body, allowing for communication between different parts of the body and coordinating various functions such as movement, sensation, and cognition. The nervous system can be divided into two main parts: the central nervous system (CNS), which includes the brain and spinal cord, and the peripheral nervous system (PNS), which includes the nerves that connect the CNS to the rest of the body. Research on the nervous system encompasses a wide range of topics, including the study of the structure and function of neurons, the mechanisms of signal transmission between neurons, the development and plasticity of the nervous system, and the role of the nervous system in behavior, cognition, and disease. Researchers in this area use a variety of techniques, including electrophysiology, imaging, molecular biology, and computational modeling, to better understand how the nervous system works and to develop new treatments for neurological disorders and injuries.
