What is the role of an interneuron in the nervous system?

Interneurons play a crucial role in the nervous system by serving as connectors between sensory neurons and motor neurons within the central nervous system (CNS). They process information received from sensory pathways and facilitate communication and coordination between different parts of the brain and spinal cord. This interaction is essential for reflex actions and complex processing required in various functions, such as learning, memory, and decision-making.

By integrating signals, interneurons help to modulate the responses sent to motor pathways, ensuring that the body reacts appropriately to stimuli. Their ability to connect various neuronal circuits allows for more complex and nuanced responses to environmental changes, which is fundamental for maintaining homeostasis and facilitating movement.
