Figure 5

Summary of the transverse propagation experiments. Graphic plot of the number of chains responding as a function of Rgj for cardiac muscle, with stimulation of only one cell (cell A1) (panel A) or with stimulation of the entire A-chain (panel B). Data for various Rol2 values (0.2, 1.0, 5.0, and 10 MΩ) are indicated. Four different Rgj values were tested: ∞ (0 channels), 100 MΩ (100 channels), 10 MΩ (1,000 channels), and 1.0 MΩ (10,000 channels). Thus, transverse propagation was depressed when there were many gj-channels (1000 or 10,000), but elevation of Rol2 could overcome this depression.
