More About Interneurons. Interneurons (also known as association neurons) are neurons that are found exclusively in the central nervous system. That means that they are found in the brain and spinal cord and not in the peripheral segments of the nervous system.There are more than 100 billion interneurons in the human body, which makes them the most abundant of the three major neuron types (along with sensory and motor neurons).hat means that they are found in the brain and spinal cord and not in the peripheral segments of the nervous system.
