The term "brain structure" refers to the organization and arrangement of different parts within the brain. It includes the overall shape, size, and position of various regions as well as the connections between them. The brain's structure is crucial for its functioning, as it determines how information is processed, stored, and retrieved by the nervous system. Different areas of the brain are responsible for different functions such as memory, movement, emotion, and perception. Understanding the brain's structure can provide valuable insights into human behavior, cognition, and neurological disorders.
