The term "brain" has its roots in ancient languages, with the modern English word derived from the Old English term "brein," meaning "mush" or "paste." Initially, people had no understanding of the brain's function and simply referred to it as a mass of gray matter. Over time, the term has evolved to reflect a deeper understanding of the brain's role in human cognition and behavior. The brain is crucial for controlling the body's functions, facilitating thought, and enabling complex behaviors. Its importance is underscored by the vast array of neurological disorders that affect brain function.
