Figure 2. CCK effect on sIPSCs in MTCs is mediated by CCK‐B receptors.

A, typical trace showing that bath‐applied CCK‐4 (100 nm, purple bar) reversibly increases sIPSCs in a MTC. B, typical trace showing that bath‐applied CCK‐8S (500 nm, red bar) exhibits no effect on sIPSCs in a MTC in the presence of CI988 (10 μm, blue bar), a selective CCK‐B receptor antagonist. C and D, quantified data showing changes in sIPSC frequency (C) and amplitude (D) by CCK‐8S (CCK) (500 nm) (n = 8), CCK‐4 (100 nm) (n = 7), CI988 plus CCK‐8S (CI+CCK) (n = 8), SR27897 (10 μm) plus CCK‐8S (SR+CCK) (n = 7), or A‐71623 (10 μm) (n = 7), a selective CCK‐A receptor agonist.
