Membranes of the astrocytic processes investing small blood vessels and the surface of the brain contain numerous arrays of orthogonally packed particles as revealed by the freeze-fracture technique. The structure of these particle arrays, which we have termed "assemblies," is the same whether tissue is prepared for freeze-fracture by conventional fixation or by quick excision and rapid freezing. However, assemblies are progressively replaced by amorphous clumps and then disappear as the… CONTINUE READING
