Capsaicin and CCK effects in cultured nodose neurones

Differential interference contrast image of neurones in culture, at baseline and stimulated neurone (A). The average peak intensity within the first 10 s shows no change in response to KCl, capsaicin or CCK (B). Numbers of responsive and non‐responsive neurones show no change in WT and KO with KCl, capsaicin or CCK stimulation (C) (n = 25 WT vs. n = 17 KO for KCL/capsaicin experiments and n = 18 WT vs. n = 34 KO for CCK experiments).
