are neurons that connect with other neurons, as compared to sensory and motor neurons. Most neurons are interneurons.

association neurons of the spinal cord; interneurons connect the anterior and posterior horns of grey matter and are involved in the reflex arc (they function within the same segment of the spinal cord)

One of the three types of neurons, these neurons communicate only with other neurons, typically within a specific brain region. go to glossary index

are neurons with either small axons that project locally within the CNS (so-called local interneurons) or long axons that relay to distant CNS targets (relay interneurons)
