I[edit]

I am interested in knowing if there is some research concerning "myelin"--"autism"--and extreme communication difficulties. That is speech initiation.

Electrical Properties - more specificity[edit]

I think it might be worthwhile to mention that myelin increases resistance *across the membrane* specifically, because when you talk about the resistance in an axon, it could be the axial resistance or the membrane resistance. —The preceding unsigned comment was added by 128.54.210.152 (talk) 03:26, 5 February 2007 (UTC).

Furthermore, for someone who doesn't fully understand biophysics, resistance is bad. So when you have a line like "The main consequence of a myelin layer (or sheath) is an increase in the speed...Myelin increases resistance across the cell membrane by a factor of 5,000 ", it seems like a contradiction. And even this is contradictory "The main consequence of a myelin layer (or sheath) is an increase in the speed...Along unmyelinated fibers, impulses move continuously as waves, but, in myelinated fibers, they hop". I alwyas imagined continuous waves to be faster than "hopping" waves. Paskari (talk) 16:46, 2 July 2008 (UTC)

shrimp myelination[edit]

perhaps there should be a section about myelination in non vertibrates? it is mentioned in the introduction, but this is a really interesting field as myelin was long held to be hallmark of higher order organisms,


this is a good review if anyone is interested

human development[edit]

It might be useful to have something in here about myelination in human infants.--76.93.42.50 (talk) 02:05, 23 February 2008 (UTC)

I second that —Preceding unsigned comment added by 85.74.156.128 (talk) 18:05, 5 April 2010 (UTC)

Or, more specifically the three times in human development that it happens. —Preceding unsigned comment added by 69.129.126.97 (talk) 22:11, 31 January 2011 (UTC)

I can't even believe there isn't a section on this. Andrewtheart (talk) 23:54, 20 March 2011 (UTC)

It isn't there for the simple reason that nobody has yet written it. If you folks care so much, one of you should write it. None of us are getting paid for this stuff, so nobody is obligated. Looie496 (talk) 01:16, 21 March 2011 (UTC)

Cystic Fibrosis[edit]

New research finding that CF affects myelination. Can someone add it to the article? — Preceding unsigned comment added by 70.40.183.46 (talk) 18:36, 7 April 2013 (UTC)

Meaning of μm/m2[edit]

I can't figure out what these units are. It's in the Function section "Myelinated fibers lack voltage-gated ion channels (approximately 25 μm/m2)".

Is it micrometers per square meter? Then the numbers seem many orders of magnitude too small... Nothing makes sense. 98.201.240.250 (talk) 17:05, 6 October 2014 (UTC)
