What is the role of interneurons in the nervous system?

Interneurons serve as critical connectors in the nervous system, playing a vital role in the processing and relay of information. These neurons facilitate communication between sensory neurons, which detect external stimuli, and motor neurons, which carry the signals that initiate movement. By linking these two types of neurons, interneurons help coordinate reflexes and complex patterns of movement, allowing for a more integrated and rapid response to various stimuli. This function is essential for the nervous system's overall operation, enabling quick and efficient reactions to changes in the environment. Interneurons are central in creating neural circuits that ensure proper signaling and coordination between sensory input and motor output.
