Figure 5. Summary of blocking glutamatergic and IP₃ receptors on drive potential generation.

A, bar chart showing the effects of APV, LY367385 (LY), MPEP, APICA, nifedipine (NIF), and xestospongin-C (Xes) on the amplitude of drive potentials, as well as the amplitude and frequency of XII motor output. B, bar chart showing the effects of LY and MPEP on the amplitude of drive potentials in steady-state intracellular Cs⁺ or Xes conditions. Asterisks above bars indicate significant effects at P < 0.05 (*) and P < 0.01 (**), respectively.
