    A Majewska
    Department of Biological Sciences, Columbia University, New York, NY 10027, USA
    J Theor Biol 212:155-67. 2001
    ..Finally, we notice that the function of some gap junctions appears linked to their precise location on the neuronal processes. We propose that the location of the gap junctions within the neuron determines their functional role...

    Proc Natl Acad Sci U S A 100:16024-9. 2003
    ..We conclude that spine motility might be involved in critical-period plasticity and that reduction of activity during the critical period enhances spine dynamics...

    A Majewska
    Department of Biological Sciences, Columbia University, New York, New York 10027, USA
    J Neurosci 20:1722-34. 2000
    ..We conclude that dendritic spines have calcium pumps and that their density and kinetics, together with the morphology of the spine neck, determine the time during which the spine compartmentalizes calcium...

    A Majewska
    Department of Biological Sciences, Columbia University, New York, New York 10027, USA
