New M-Cell Page for Class Project[edit]

Myself and three other student editors have rewritten this magnocellular cell page and have added a LOT of new content, all sourced, as we felt the original article was inadequate to explain such a complicated cell pathway so vital to the visual system. We have written this page for a class assignment, and our goal was to create a page that was a comprehensive overview of the structure, function, history, and importance of this cell type. As this is for a class, we would greatly appreciate it if other editors refrain from making any major changes to the page until our semester is over in May. We gladly welcome any feedback or constructive criticism on the talk page. ScientificStarchild (talk) 04:13, 3 April 2017 (UTC)[reply]

Not going to happen and if your instructor put that idea into your head, please have them check with the class liaison. Nobody owns any WP page. Jytdog (talk) 04:15, 3 April 2017 (UTC)[reply]

I never told my students that they own pages. I did say that if someone (a student or anyone else) is in the midst of a major edit, it is appropriate to post that on the talk page of the article. My understanding of Wikipedia etiquette is that under those circumstances other editors should start by making suggestions on the talk page before just changing things in the midst of someone else's edit. I cannot guaranty that this is what would happen but clearly you do not agree with this practice as you have hassled my students in the past. If you have a problem with how the Education Foundation is running this program you should take it up with them, not my students. MMBiology (talk) 14:37, 3 April 2017 (UTC)[reply]

Please WP:FOC. Jytdog (talk) 17:57, 3 April 2017 (UTC)[reply]

This added content was a mess, but this is due in part to ambiguities in the literature, where sometimes parasol cells are called "M cells", and sometimes "M cells" is used to refer to cells in the mangnocellular layers of the LGN.

If you look at navboxes and the infoboxes on this page and parasol cell, you can see that this page was about cells in the M layers of the LGN, and parasol cell was about the retinal ganglion cells that project to the M layer.

Most of the content added here was about parasol cells, and I have moved it there. Am doing other cleanup. Jytdog (talk) 06:56, 3 April 2017 (UTC)[reply]

I will look this over later once I have had a chance to read over some of the sources. MMBiology (talk) 14:37, 3 April 2017 (UTC)[reply]

btw, if you want your instructor to grade what you did, it is in the history, in the version here. Jytdog (talk) 11:10, 3 April 2017 (UTC)[reply]

Thank you, I am well aware that I can see the history and figure out what belongs to my students and what does not. MMBiology (talk) 14:37, 3 April 2017 (UTC)[reply]

Prosopagnosia content[edit]

Content below was originally source to a primary source; this is not OK per WP:MEDRS

Prosopagnosia

Prosopagnosia is a disability to recognise familiar face identity. People with this condition can see faces clearly, but do not have recognition of identity of the face. The acquired version of prosopagnosia is associated with brain damage while the developmental prosopagnosia is associated with a delayed interrogation of magnocellular and parvocellular inputs in forming a face percept.^[1]

Our article on Prosopagnosia doesn't mention magnocellular cells or the LGN. Did a pubmed search for reviews here and found one ref PMID 26208417 which looks promising as it discusses LGN but I can't get access to that right now. Could perhaps be used to support this content.

Structure[edit]

The structure section mainly focuses on the LGN as a whole.

It's unclear from the structure section which neurons (parasol or midget) actually supply the magnocellular cells in the LGN.

The reader has to go to the lead of Parasol_cell to find out that it is Parasol retinal ganglion cells that actually synapse with the magnocellular neurons.

Whilst I do feel it is definitely necessary to explain that 3 types of ganglion cells supply the LGN, this section also needs to clearly specify what input the magnocellular neurons have.
