PV+ cell loss in CA1 and CA3 regions of the hippocampus and its relationship to decrease in theta and gamma power in the CA1 region

significant difference at 0.05 level

note1: statistical comparison using Student’s t-test included all saline and ketamine treated rats

note2: correlation between PV+ cell loss and oscillations (Spearman and R2) was calculated for experiments in which there was a PV cell loss, i.e. included 5 of 6 ketamine treated rats
