Figure 2. Morphological features of cells with large amplitude slow waves filled with propidium iodide.

A, slow waves recorded from the cell shown in B. The resting membrane potential was −65 mV. The image of the cell injected with propidium iodide for 4 min was digitally reconstructed on a confocal microscope, and it shows the distinctive morphology of an ICC-MY (B). The scale bar B in represents 50 μm.
