Homeostatic intrinsic plasticity was dependent on PKA pathway.
A: representative traces (left) and
bar graph (middle; at +400 pA injection) and plots
(right) showing that treatment of PKA inhibitor KT 5720
(KT) prevented homeostatic intrinsic plasticity in cerebellar PCs.
B: bar graph showing the reduced
Rin was recovered by KT (500 nM). Closed
black square, KT only; closed gray square, deprived + KT; open black square,
control; open gray square, deprived. Control and deprived values are as
described in Fig. 1. Asterisks in
A marked by post hoc Tukey's test, pairwise comparison
followed by 2-way repeated-measures ANOVA, compared with deprived and
deprived + KT. Asterisks in B marked by 2-sample
t-test; *P < 0.05,
***P < 0.001; n.s., no significance.
