Acetylcholine
Why has the term neuromodulator been used to describe acetylcholine in the sentence "...releasing neuromodulators like acetylcholine"? In interneurons, it clearly functions as a neurotransmitter. —Preceding unsigned comment added by 212.149.175.249 (talk) 07:56, 3 August 2010 (UTC)

Separate brain and spinal cord sections?
I wondered if this is a bit confusing. The text about the various meanings of this term is mixed together while the only diagram is of a reflex arc (i.e. in the spinal cord). I'd quite like to have two headings, one for spinal cord interneurons and one for cortical inhibitory interneurons. Anyone have any opinions? I'll have a think about it and get back to it when I get a chance. I have a feeling this could get very complicated... HilJackson 09:51, 4 July 2006 (UTC) Talk to me‼

Example paragraph
I'm pretty sure the CNS example ("An example of interneurons is inhibitory interneurons in the neocortex which selectively inhibit sections of the thalamus...") and reference to SICI are inaccurate. The paragraph should probably be scrapped entirely but I thought I'd check first to see if anyone wants to do some research and clean it up.PhineasG (talk) 14:16, 12 February 2008 (UTC)

Definitely incorrect. I'm currently writing a thesis on the topic. Upon defending in a few weeks, I'll try to expand and clean up this page. 68.46.183.96 (talk) 21:03, 8 July 2008 (UTC)

Bipolar neuron
"Interneuron" is not synonymous with "bipolar neuron". An interneuron is defined as a neuron that connects afferent and efferent neurons, whereas "bipolar neuron" refers to a specific structural class of neuron (notably found in the retina). Bipolar neurons are interneurons, but not all interneurons are bipolar neurons. Hence, the terms cannot be used interchangeably. Fuzzform (talk) 18:46, 9 September 2008 (UTC)

Definitions
I've just rewritten the lede from to I relied on the following sources:


 * An interneuron is a neuron that connects neurons with neurons.
 * An interneuron is a relatively short neuron whose primary task is making connections between other neurons.
 * An interneuron is a neuron located in the spinal cord that receives the nerve impulse from the sensory neuron and relays the impulse to the motor neuron. (In a section addressing the reflex arc.)
 * An interneuron is a nerve cell whose cell body and axon reside entirely within the central nervous system.
 * Its name implies that an interneuron is intercalated between two other neurons ( Fig. 1.12). Even though, strictly speaking, all neurons with axons that do not leave the CNS are thus interneurons, the term is usually restricted to neurons with short axons that do not leave one particular neuronal group.
 * An interneuron is a neuron that carries nerve impulses from one neuron to another. Some interneurons pass impulses from sensory neurons to motor neurons.
 * MeSH descriptor data Retrieved 16 February 2012. Most generally any neurons which are not motor or sensory. Interneurons may also refer to neurons whose axons remain within a particular brain region as contrasted with projection neurons which have axons projecting to other brain regions.

My main motivation was to remove the implication that interneurons only connect afferent with efferent neurons, and - though I'm not certain on this point - allow for the possibility of PNS interneurons. I have a vague memory that an interneuron stands between the ventral root and its motoneurons. --Anthonyhcole (talk) 07:10, 16 February 2012 (UTC)

 * I think that's a good change. The new definition may not be perfect, but it's surely a big improvement. Looie496 (talk) 00:08, 17 February 2012 (UTC)

Myofibrils
In the section "The withdrawal reflex", myofibrils are not the same as muscle fibres. The muscle fibre is the whole muscle cell or myocyte, and the miofibrils are inside the cell. The neuromodulator acetylcholine depolarize the cell, not the miofibrils. It interacts with the plasma membrane (sarcolemma) in the neuromuscular junction.--Miguelferig (talk) 19:55, 5 August 2015 (UTC)
 * As a matter of fact, virtually everything in that section was wrong. After thinking about it, I decided the best thing to do was to remove the whole section.  It would certainly be good to have a section on the role of spinal interneurons in reflexes, but I think it would be easier to write something from scratch than to fix all the errors there.  (It has the look of a student class assignment, one of the most common sources of junk in Wikipedia.) Looie496 (talk) 22:01, 5 August 2015 (UTC)
