Fig. 3

Electron micrographs of dissociated hippocampal neuronal somas under control condition (a) and upon depolarization with high K+ (b). Large arrows point to subsurface cisterns where the endoplasmic reticulum (ER) comes in close contact with the plasma membrane (PM). The contact area between ER and PM (small arrows point to the borders of the contact area) conspicuously decreased upon depolarization. Scale bar = 0.1 μm
