What is the function of interneurons?

Interneurons play a critical role in the nervous system, particularly within the central nervous system (CNS). Their primary function is to collect and direct signals between sensory neurons, which receive input from the environment, and motor neurons, which carry signals to muscles to elicit movement. Interneurons serve as a bridge facilitating communication and processing within the CNS, allowing for complex reflexes and higher order brain functions.

In addition to connecting sensory and motor pathways, interneurons are integral to processing information. They can integrate signals from various sources, enabling the CNS to generate appropriate responses. By modulating the flow of information, interneurons contribute to functions such as reflex actions, learning, and memories. Their role in signal direction and processing underscores their essential nature in the functioning of neural circuits.
