Neurology is the branch of science and medicine dedicated to the study of the nervous system. This complex biological network includes the brain, the spinal cord, and peripheral nerves, which facilitate communication between different parts of the body and control bodily functions. The field investigates the structure and function of neural tissue, focusing on how electrical and chemical signals are generated and transmitted. Research in this area explores the mechanisms of perception, movement, cognition, and sensory processing, providing foundational knowledge for understanding how the central nervous system regulates homeostasis and processes information necessary for life.
