    Postsynaptic membrane fusion and long-term potentiation (1998)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1998-02-07
    Description: The possibility that membrane fusion events in the postsynaptic cell may be required for the change in synaptic strength resulting from long-term potentiation (LTP) was examined. Introducing substances into the postsynaptic cell that block membrane fusion at a number of different steps reduced LTP. Introducing SNAP, a protein that promotes membrane fusion, into cells enhanced synaptic transmission, and this enhancement was significantly less when generated in synapses that expressed LTP. Thus, postsynaptic fusion events, which could be involved either in retrograde signaling or in regulating postsynaptic receptor function or both, contribute to LTP.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Lledo, P M -- Zhang, X -- Sudhof, T C -- Malenka, R C -- Nicoll, R A -- New York, N.Y. -- Science. 1998 Jan 16;279(5349):399-403.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Cellular and Molecular Pharmacology, University of California, San Francisco, CA 94143, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/9430593" target="_blank"〉PubMed〈/a〉

    Long-term potentiation--a decade of progress? (1999)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1999-09-18
    Description: Long-term potentiation of synaptic transmission in the hippocampus is the leading experimental model for the synaptic changes that may underlie learning and memory. This review presents a current understanding of the molecular mechanisms of this long-lasting increase in synaptic strength and describes a simple model that unifies much of the data that previously were viewed as contradictory.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Malenka, R C -- Nicoll, R A -- New York, N.Y. -- Science. 1999 Sep 17;285(5435):1870-4.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Nancy Friend Pritzker Laboratory, Department of Psychiatry and Behavioral Sciences, Stanford University School of Medicine, Stanford, CA 94304, USA. malenka@stanford.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/10489359" target="_blank"〉PubMed〈/a〉

    Bidirectional control of quantal size by synaptic activity in the hippocampus (1996)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1996-03-01
    Description: Analysis of strontium-induced asynchronous release of quanta from stimulated synapses revealed that long-term potentiation and long-term depression in the CA1 region of the mammalian hippocampus are associated with an increase and a decrease, respectively, in quantal size. At a single set of synapses, the increase in quantal size seen with long-term potentiation was completely reversed by depotentiating stimuli. Long-term potentiation and depression are also associated with an increase and decrease, respectively, in the frequency of quantal events, consistent with an all-or-none regulation (up or down) of clusters of alpha-amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid (AMPA) receptors, a change in the release of transmitter, or both.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Oliet, S H -- Malenka, R C -- Nicoll, R A -- New York, N.Y. -- Science. 1996 Mar 1;271(5253):1294-7.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Cellular and Molecular Pharmacology, University of California, San Francisco 94143-0450, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8638114" target="_blank"〉PubMed〈/a〉
