Neurons that connect only with other neurons, and not with either sensory cells or muscles. They are thus involved in the intermediate processing of signals.
Interneurons (also called connector or association neurons) link neuron to neuron, and integrate sensory and motor neurons. Only very occasionally do motor neurons and sensory neurons connect directly.
Type: Term Pronunciation: intĕr-nū′ronz Definitions: 1. Combinations or groups of neurons between sensory and motor neurons that govern coordinated activity.
(in;ter-noor;onz) Multipolar neurons interposed between sensory (afferent) and motor (efferent) neurons and confined entirely within the central nervous system; also called association neurons.
Neurons that process signals from one or more sensory neurons and relay signals to motor neurons. Aka connector neurons.
Brain neurons that relay messages from sensory neurons to other interneurons or to motor neurons.
