Fig. 3. Simultaneously recorded pause and burst on individual heat trials.
A, B and C are three on-cell/off-cell pairs. Oscilloscope traces (duration 10 s) show activity of an off-cell (top trace in each case) and on-cell (lower trace). The arrow indicates the exact time of the withdrawal. The trials shown for pairs A and B and the first trial for pair C (C1) are examples of the pause in off-cell discharge beginning before the on-cell started firing. Pair C also showed one trial (C2) on which the on-cell began to fire before the final off-cell spike (overlapping spike of the off-cell marked by an asterisk). Lag between final off-cell spike and first on-cell spike are given for each trial.
