Interneurons are a form of neuron in the human central nervous system and are responsible for the processing and communication of information.

  • Interneurons can be classified as local circuit neurons and relay neurons:
    • Local circuit interneurons have short axons and form circuits with nearby neurons to analyse small pieces of information.
    • Relay interneurons have long axons and connect circuits of neurons in one region of the central nervous system with those in other regions.
  • Interneurons form nodes within neural circuits, enabling communication between sensory or motor neurons and the central nervous system.
  • The interaction between neurons and interneurons are essential to our living bodies but also enable the brain to perform highly complex processes such as sense-making.
