Within the reflex circuit, the Interneuron allows the spinal cord to control certain reflexes without the brain's help.
Interneurons are the intermediary neurons that connect the spinal motor and sensory neurons. Interneurons can communicate with one other as well as with sensory and motor neurons to exchange impulses, resulting in circuits with different levels of complexity. They are multipolar in a similar way to motor neurons.
The neurons that connect other neurons, such as sensory and motor neurons as well as other interneurons, are known as interneurons. Interneurons make up the entirety of the central nervous system, including those found in the brain.
