What is the primary role of a central pattern generator in behavior?

• A. It integrates sensory input to plan movements
• B. It produces rhythmic motor patterns autonomously, such as walking or swimming
• C. It encodes long-term memory
• D. It modulates hormone release to control aggression

Answer: (B)

Central pattern generators create rhythmic motor outputs automatically, generating the basic timing for repetitive movements like walking, swimming, or breathing. They can run without conscious planning, though sensory feedback can tweak the rhythm as needed. That autonomous rhythm generation is what sets them apart from systems that plan movements or encode memories, or from hormonal control of behavior. So the primary role is to produce rhythmic motor patterns autonomously.
