Social defeat stress does not affect neuronal network activity in the hippocampus. a Histological verification of a recording site in hippocampal CA1 area. The yellow arrow indicates the tip of the electrode tract. b Comparison of LFP power in theta, slow gamma, and fast gamma bands between naïve and defeated mice. P > 0.05, Student’s t-test. c A representative unfiltered hippocampal LFP trace (top) and its filtered (150–250 Hz) LFP trace (bottom). A ripple event is marked by the red dot. The average number of ripple events per second is shown in the right panel. d Histological verification of a recording site in hippocampal CA3 area. The yellow arrow indicates the tip of the electrode tract. e Comparison of LFP power in theta, slow gamma, and fast gamma bands between naïve and defeated mice. P > 0.05, Student’s t-test. f Comparison of the average number of ripple events per second between naïve and defeated mice. P > 0.05, Student’s t-test (color figure online)
