Block of 1S,3R-ACPD effects by mGluR antagonist MCPG. Top, Inspiratory discharges of C4 root are not significantly affected by locally applied 1S,3R-ACPD (200 μm) in the presence of MCPG (800 μm, bath). Each trace is the average of 10 integrated inspiratory discharges. Bottom, Summary of MCPG (800 μm, bath) effect on 1S,3R-ACPD (200 μm, local) action from seven preparations.Vertical bars, SEM.
