      The interneuron is a major neuroarchitectural element within the arthropod central nervous system, both in terms of numbers and diversity of form.

      Another important difference between interneuron and pyramidal cell spines is the number of synaptic boutons. The spines of interneurons are covered by numerous excitatory synaptic boutons (four to eight synapses per spine).

      Embedded within these spinal circuits are local interneurons. An interneuron is generally defined as a neuron that only synapses onto other neurons. In the central nervous system, interneurons are considered to be the neurons that have local rather than long-distance projections.
