Definition of interneuron in English:
interneuron
(also interneurone)
noun ˌɪntəˈnjʊərɒnˌin(t)ərˈn(y)o͝orˌän
Physiology A neuron which transmits impulses between other neurons, especially as part of a reflex arc.
〔生理〕中间神经元
Example sentencesExamples
- The medial stripe, nearest the midline, which becomes the ventral region of the neural tube, gives rise to motor neurons, whereas the lateral stripes give rise to interneurons and sensory neurons.
- It is proposed that endogenous opioid peptides can activate PAG output neurons by inhibiting an inhibitory interneuron.
- The cells that responded to nerve stimulation were most likely principal neurons and not interneurons, because fast excitatory postsynaptic potentials were recorded in these cells.
- The exact mechanism of action is not known, but activation of the spinal interneurones or adrenergic neurones, which inhibit bladder activity, has been postulated.
- Evidence from both species supports the conclusion that the excitation derives from glutamatergic premotor interneurones and cholinergic homonymous motorneurones.
Derivatives
adjective
Physiology Our interneuronal connections in our brain, for example, process information at chemical signaling speeds of a few hundred feet per second, compared to a billion feet per second for electronics - electronics is a million times faster.
Example sentencesExamples
- Individual cells apparently often control similar interneuronal or motor functions from animal to animal, and again, structural and functional parallels often persist across larger taxonomic groups.
- Hanson has shown that amphetamines increase the concentration of catecholamines in the synaptic cleft by stimulating their release from the interneuronal storage vesicles.
- These abnormal responses are generally attributed to the removal of inhibitory signals that influence the interneuronal networks controlling the response.
- But the scan is not yet at a high enough resolution to recreate the interneuronal connections, synapses and neurotransmitter concentrations that are the key to capturing the individuality within a human brain.
Origin
1930s: from internuncial + neuron.
