Postsynaptic Density - Structure

Structure

The structure and composition of the PSD have been the focus of numerous molecular studies of synaptic plasticity, a cellular model of learning and memory. PSDs are sized on the order of 250 to 500 nanometres in diameter and 25 to 50 nanometres in thickness, depending on the activity state of the synapse.

Famous quotes containing the word structure:

    Vashtar: So it’s finished. A structure to house one man and the greatest treasure of all time.
    Senta: And a structure that will last for all time.
    Vashtar: Only history will tell that.
    Senta: Sire, will he not be remembered?
    Vashtar: Yes, he’ll be remembered. The pyramid’ll keep his memory alive. In that he built better than he knew.
    William Faulkner (1897–1962)

    A structure becomes architectural, and not sculptural, when its elements no longer have their justification in nature.
    Guillaume Apollinaire (1880–1918)

    For the structure that we raise,
    Time is with materials filled;
    Our to-days and yesterdays
    Are the blocks with which we build.
    Henry Wadsworth Longfellow (1809–1882)
