Figure 1. Effect of PACAP27 on an IMG neurone that received ongoing excitatory synaptic input from the colon.

Figure 1

Top panel, a single 50–150 ms pressure application of PACAP27 (5 μm) evoked an intense and long lasting excitatory response accompanied by a marked increase in the frequency of F-EPSPs and APs and a slow depolarization of the membrane potential. Bottom panel shows portions of the recording on an expanded time scale to reveal individual post synaptic potentials.
