  • For decades, scientists have not known how the appropriate number of these interneurons is determined, how many are formed, when they die, and how many survive after reaching the cerebral cortex.
  • inhibitory interneuron
  • types of interneurons
  • interneuron cell

Examples

  • The interneuron connects sensory neurons and motor neurons to allow for coordinated movement.

  • Clearly there are still more than a few misconceptions about the structural differences between sensory neurons, interneurons, and motor neurons.

  • So we think that those many small neurons, many interneurons, many mostly Gabaergic interneurons.

  • The neurons messaging the stem cells are parvalbumin-expressing interneurons.

  • Further analysis revealed that a subcircuit of three C. elegans sensory neurons and one interneuron was necessary for this response (Shao et al. 2016).

  • Small-diameter afferent fibers connect to interneurons and synaptic mechanisms, which in turn produce long-lasting hyperexcitability.

    Academic text (1999)
  • Based on this theory, the UCSF team had expected that only a fixed and small number of transplanted embryonic interneurons would survive in the brains of older recipient mice, regardless of how many they transplanted.

  • Researchers found that interneurons help regulate the flow of information in neural circuits.

  • Damage to interneurons can disrupt communication within the nervous system, leading to various movement disorders.

Surface Forms

interneuron singular
interneurons plural

Morphology

interneuron = neuron (transparent) = inter + neuron

Formed by the productive prefix 'inter-' (between/among) + 'neuron'; learners who know 'neuron' and 'inter-' can infer it denotes a neuron connecting others.

Etymology

Interneuron comes from inter- meaning 'between' and neuron meaning 'nerve' or 'nerve cell'. So an interneuron is a nerve cell that sits 'between' other neurons and passes signals from one to another.
