(A) CNO application in wild-type littermates. Top: Experimental protocol. Orange box represents 5-HT and purple boxes represent CNO application. Bottom: upstate incidence during 5-HT and 5-HT+CNO application, patches represent 95% confidence interval, lines represent standard deviation (n = 11 cells in four mice, baseline = 0.91 ± 0.10, 5-HT = 0.09 ± 0.04, CNO = 0.01 ± 0.01, p baseline vs 5-HT = 0.0004, p baseline vs CNO <10−4, Kruskal-Wallis test) (B) Same as (A) but in in PV-hM4Di mice (n = 10 cells in four mice, baseline = 1.02 ± 0.08, 5-HT = 0.04 ± 0.03, CNO = 0.08 ± 0.07, p baseline vs 5-HT < 10−4, p baseline vs CNO = 0.0003, Kruskal-Wallis test).
