(A) Nuc/cyt ratio of α or βCaMKK in PV+ cells did not change following 40K for 2 min.
(B) Nuc/cyt ratio of pan-CaMKI staining increased in PV+ but not excitatory neurons, with 40K for 1 min, and was prevented by nimodipine or by STO609.
(C) pCaMKI immunostaining increased in both cytoplasm and nucleus of PV+ cells following 3 min of 40K.
(D) Following 40K for 1 min, nuclear CaM values were correlated with nuclear pCaMKI values in PV+ cells (Pearson correlation, R2 = 0.52, p<0.001).
