Talk:Long-term potentiation

message: can i remind whoever wrote that, or an experienced editor, that the majority (i assume all from this article) of research on LTP has been done on the hippocampus. is it a coincidence that the results were all about memory and spatial navigation and memory? what would happen if we would investigate it elsewhere? it seems like LTP however much sense it makes as physical components of memory, could have implications elsewhere. if anyone could help enlighten me on this topic please do. 161.76.137.146 (talk) 05:51, 23 November 2011 (UTC)
replies: text: LTP has been suggested as the mechanism behind certain chronic pain conditions, but I'm not sure how far advanced that theory is. --Anthonyhcole (talk) 08:44, 23 November 2011 (UTC)

message: I would like to note that an IP editor has twice attempted to add a section on PTSD, and been reverted.  The section consists of two sentences.  The first might be acceptable, or at least is worth discussing.  The second is referenced to an article in Medical Hypotheses.  There is essentially universal agreement among Wikipedia medical editors that that journal is not a usable source, because the articles there receive no peer review whatsoever.  So that material won't be usable unless a better reference can be found, a reference consist with WP:MEDRS. Looie496 (talk) 23:02, 2 April 2013 (UTC)

message: Human cellular prion protein (PrPC) is able to bind up to 5 Cu2+ ions at [fentamolar] via its octapeptide repeats, inducing a dramatic conformational change that permits the binding of PrPC to the GluN1 subunit of NMDA receptors (NMDARs). This interaction reduces NMDAR affinity for the co-activators Gly and D-serine. Gly/D-serine inordinately retard the desensitisation kinetics of NMDARs in a concentration-dependent fashion, leading to overactivation and excitotoxicity via excessive Ca2+ influx. By reducing Gly affinity, Cu2+ bound PrPC ameliorates NMDAR overactivation by reducing Gly-induced non-desensitising currents, permitting normal receptor desensitisation following bouts of activity.Stys PK et al, 2012 
In Alzheimer's, the cytotoxic amyloid-beta oligomers produced from the incorrect cleavage of the APP protein bind to PrPC, preventing its interaction with Cu2+ and subsequent association with NMDARs. The loss of NMDAR modulation through this mechanism may be one of the primary reasons why LTP is hampered in Alzheimer's disease. NMDAR overactivation results in Ca2+-mediated excitotoxicity due to a complete loss of homeostasis regarding calcineurin, CaMKII, calpain, caspase, protease, lipase and endonuclease activity, resulting in cellular necrosis.
The loss of LTP explains the poor short-term memory function of AD sufferers, while the neuronal death from excitotoxicity explains the eventual failure of their long-term memory as strengthened synapses are obliterated, both of which can be explained by amyloid-beta dependent inhibition of PrPC. Of course, other factors do play a part in Alzheimer's, but this one seems to link NMDARs, synaptic dysfunction, short-term/long-term memory loss and glutamatergic cellular death within the cerebral cortex and hippocampus.
I've been doing a lot of research into AD, Parkinson's and other neurodegenerative diseases, from a proteomics, as well as the memory dysfunctions aspects of the diseases. Just thought you might be interested in this given your interest in LTP and, presumably, memory.

message: Here is an exact source for the quote about Associativity. In fact it is directly copied-and-pasted from this textbook. I would add it myself, but the page is semi-locked, and so I can't. Also, I don't know how to properly cite references. Purves D, Augustine GJ, Fitzpatrick D, et al., editors. Neuroscience. 2nd edition. Sunderland (MA): Sinauer Associates; 2001.
