Interneurons are also referred to as relay neurons, connector neurons, intermediate neurons and local circuit neurons each of which helps to explain their function.
Interneurons form nodes within neural circuits, enabling communication between sensory or motor neurons and the central nervous system.
Interneurons can be further broken down into two groups: local interneurons and relay interneurons.
Local 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 brain with those in other regions.
The interaction between interneurons allows the brain to perform complex functions, such as sense-making.
