I suggest adding more detail describing how the connectivity of the olfactory bulb informs theories of its function. Included in this general wish, I have a few specific topics that, if expanded, would make this entry more informative.

Explain the term "sponges" It cannot mean a being of the phylum Porifera for those are lacking a brain. —Preceding unsigned comment added by 67.161.3.101 (talk) 06:03, 2 May 2009 (UTC)[reply]

• Expand upon: function of periglomerular cells as carriers of lateral inhibition and centrifugal modulation (5HT, others?).
• Expand upon: function of granule cells in: auto-inhibition, lateral inhibition, centrifugal modulation (pregnancy block, others?)
• Add: theories of information coding by mitral cells and its relationship (or lack of) to "glomerular maps"
• Add: mention of adult neurogenesis from sub-ventricular zone
• Add: mention of insect models of antennal lobe, potential new stub for "antennal lobe"

cheers,

It is quite possible, however, that function has not been conserved with structure, indicating that olfactory bulbs of distant species may be paralogs of each other.

I'm not sure what this is trying to say, but I suspect that paralog is being used incorrectly (even putting aside the fact that the term usually refers to genes, not structures). Perhaps the use of the term is based on the mistaken belief that divergence of function makes things paralogs. Or perhaps the intended meaning is that the olfactory bulbs are analogous but not homologous, and their similarities are due to convergent evolution. 71.178.58.56 (talk) 01:40, 16 October 2009 (UTC)[reply]

• Whatever it was trying to say, it was not accurate. The fly antennal lobe & vertebrate olfactory bulb are most certainly not homologous structures (contrary to the previous version of the article) -- they are independently evolved, not evolved from a common ancestor that shared a similar structure. I changed the article to reflect this, but retained the suggestion that the similar structures may reflect convergent evolution. Of course, it still needs refs and could use more detail, but at least it's not wrong now. Gould363 (talk) 22:35, 26 October 2011 (UTC)[reply]

I am a little concerned that the only mention of its relation to the limbic system is in the category at the bottom. I mention this not only because it is part of this system, but because a relation to emotions, as I have learned from a psychologist.--John Bessa (talk) 00:59, 30 August 2010 (UTC)[reply]

It would be extremely helpful to give information about what superstructures the olfactory bulb is considered a sub-part of. If it is not in the telenchephalon, where is it? Also, is it a part of the olfactory gyrus, or only linked to it? And is it generally considered part of the limbic system as suggested above? I hope that a thorough, rather than superficial description of where it belongs will be added.

I added additional information about the accessory olfactory bulb and how it works in relation to the the main olfactory bulb. In addition, I included information about olfactory dysfunction and the ways they impact the olfactory system. This is part of my Neuroscience 100 class at Middlebury College. We will continue editing the page based on feedback from fellow wikipedia editors, peers, and professors.Vmanjarrez Talk Page Vmanjarrez (talk) 22:04, 14 November 2013 (UTC)[reply]

I have added further information about the olfactory bulb layers and the connections between the olfactory bulb and the hippocampus, amygdala, and olfactory cortex as a part of my Neuroscience 100 class at Middlebury College. We will continue editing the page based on feedback from fellow wikipedia editors, peers, and professors. Emmaskyewilkinson (talk) 19:47, 12 November 2013 (UTC)[reply]
