Figure 3

Typical examples of pulpal unit responses to 5-HT application and the effects of saline (a) and DGL (b) on the 5-HT-induced responses. The arrows indicate the time points of 5-HT (red arrows) and saline or DGL (green arrows) applications. Insets above the histograms show raw spikes during blue lines.
