What is the primary function of interneurons in the central nervous system (CNS)?

Interneurons play a crucial role in the central nervous system by connecting sensory pathways, which carry information from the body to the brain, with motor pathways, which are responsible for sending signals from the brain to muscles. These neurons facilitate communication and integrate information between sensory input and motor output, allowing for complex reflexes and processing of sensory information. This connectivity enables the CNS to coordinate responses and perform higher-order functions, such as learning and decision-making. By bridging the gap between sensory and motor neurons, interneurons are essential for the overall integration and functionality of the nervous system.
