Fig. 4. Modulation of the theta synchronization between the PFC and the HPC. (A) Average PSI between the PFC and the HPC calculated at each timepoint of the wheel-turning epoch. Error bars for SEM. Dotted vertical lines at time 0 and time 0.5 indicate the onset of wheel-turning activity and the onset of MFB stimulation, respectively. Green and gray shades indicate the intervals in which the PSIs in the ICSS session deviated from the pre-ICSS sessions before and after the stimulation onset, respectively. (B) Mean PSIs in the interval from 0.4 to 0.5 s. Error bars for SEM. (C) Mean PSIs in the interval 0.5 to 0.7 s. *for p<0.05, repeated measures ANOVA and post hoc comparison with the Tukey-Kramer method.
