Central nervous system
The nervous system comprises two main divisions: the central nervous system (CNS), which consists of the brain and spinal cord, and the peripheral nervous system (PNS), encompassing all other neural structures. The CNS is responsible for receiving, processing, and responding to sensory input. CNS is very vital for higher organisms to exist. Thus, disorders and diseases associated with it are of great concern, and therefore, active research is essential in the field of the nervous system.
Brain disorders
Brain disorders are diseases associated with the brain, which can significantly influence personality, behavior, cognitive functions, and day-to-day activity. These conditions can encompass traumatic injuries, neoplasms, infections, and dementia. These factors can exert varying effects contingent on disease type, localization, and severity.
