I'm sorry I don't know what you're refering to Paskari 19:31, 27 April 2007 (UTC)

number of horizontal cells

The fundemental plan of the retina (R Masland) claims that there are only 2 types of horizontal cells, whereas this pages claims that number should be 3. Paskari 12:41, 13 March 2007 (UTC)

I put the incomplete tag at the top because I think that there could be many mistakes on this page, I am pretty sure there are only two kinds of horizontal cells. Also the original article led the reader to belive that horizontal cells only provide inhibition for cones, not rods.Paskari 14:56, 13 March 2007 (UTC)

I see what the author of this site was talking about, the third type of horiontal cell (discovered by Ahnelt and Kolb) is H1 in disquise, I'll update the page to reflect this. Paskari 14:12, 2 April 2007 (UTC)

Center/Surround Inhibition

The inhibition model i presented using the horizontal cells to deliver negative feedback is the one proposed in From Neuron to Brain. The Computational Neuroscience of Vision presents a different model which is much simpler. If anyone knows what I'm talking about, please let me know which one u think is better, as I am a little confused on the subject as well.Paskari 18:09, 13 March 2007 (UTC)

Edited organization section

I cleaned up some of the text in this section. First the text was incorrect on some facts, I made sure to list the appropriate functionality of all three horizontal cells. also I removed the sentance which claimed that all horizontal cells are multipolar. I don't even know what that means, and if somebody does know, then please go ahead describe it in more detail Paskari 14:22, 2 April 2007 (UTC)

editing problem

someone edited the functional properties section and now the whole thing makes no sense. Horizontal cells hyperpolarize in the presence of glumate, whereas someone changed point 3 to read Reduction of glutamate depolarizes the H bipolar cell. I'm going to see if I can roll that back Paskari 19:31, 27 April 2007 (UTC)

Revert

I'm going to wait a few days, then I will revert back to the 14:24, 2 April 2007 point. someone completely rearranged up the functional properties section. If I am the one who is cofused, then please bring it to my attention ASAP Paskari 19:36, 27 April 2007 (UTC)

I'm going to go ahead and revert Paskari 08:54, 2 May 2007 (UTC)

GABAergic feedback from horizontal cells to photoreceptors

I would like to note that the idea that feedback from horizontal cells to photoreceptors is mediated through GABA is highly dubious. In primate this has been demonstrated by Verweij J, Hornstein EP, Schnapf JL in an articel entitled "Surround antagonism in macaque cone photoreceptors" published in 2003.

-- I agree with this. I think the primary canidates for feedback inhibition are pH changes and ephaptic mechanisms. -- I agree with this too. The depolarisation of the Horizontal Cell leads to output or pre-synaptic connections to Bipolar cells cells via sign-conserving conventional synapses (unlikely mediated by GABA).

Rather than perpetuate an inaccuracy, this content needs to be either revised or removed. — Preceding unsigned comment added by Jkokavec (talk • contribs) 06:27, 13 June 2013 (UTC)

Article's section "References"

I think it would be good to clean up the References in this article.

First, reference 3 is a duplicate of reference 2 (Wässle and Riemann, 1978). I propose that we delete ref. 3, and re-point 3 to 2. If nobody objects I will do it tomorrow or this coming weekend. Ion Soggo (talk) 17:00, 1 September 2016 (UTC)

I replaced the 2 references with one.Ion Soggo (talk) 17:55, 2 September 2016 (UTC)
