Interneurons are the central nodes of neural circuits, enabling communication between sensory or motor neurons and the central nervous system (CNS). They play vital roles in reflexes, neuronal oscillations, and neurogenesis in the adult mammalian brain.

What is the role of the interneuron in a reflex?

Interneurons play a vital role in the integrative processes of the nervous system. In reflexes, they coordinate the motor response necessary to address a stimulus. Additionally, these neurons are responsible for communicating with the brain for cognition.

What happens if the interneuron is damaged?

When they're damaged, it can interfere with the brain's ability to communicate with the muscles and organs, and can result in the loss of motor function, sensory function, or both. Damage to the peripheral nerves can also result in peripheral neuropathy, which is a general term for malfunctioning of these nerves.
