👉 In neuroscience, a "brainstem" is a group of structures that regulate and control the functions of the central nervous system (CNS). It encompasses the brain's lowest level of structure. These structures are responsible for transmitting signals from the peripheral nerves to the brain. They include the spinal cord, which carries sensory information, and the cranial nerves, which carry motor and autonomic signals. The term "brainstem" is used in medical terminology to refer specifically to these structures within the CNS.
