Fig. 5

a, b Peri-event ACC–hippocampus cohereograms for correct and error trials for the control (a) and STZ (b) groups. Frequency is shown on the y-axis and time relative to trial start (TS) is on the x-axis. The z-axis legend on the far right applies to all plots. c Theta coherence trial outcome difference scores. Mean error trial coherence divided by mean correct trial coherence per session. d, e Theta band power in the hippocampal and ACC. Spectral power is on the y-axis and group and trial outcome on the x-axis. Correct trials: solid bars; error trials: striped bars. f Coherence difference scores by delay length. g, h Distribution of theta coherence values for short (g) and long (h) delay trials. Control and STZ groups on correct (left) and error (right) trials. Magnitude squared coherence is on the x-axis and proportion of trials is on the y-axis. Dotted lines show the median coherence value. In all plots, control values are in gray and STZ are shown in magenta. **p < 0.01; *p < 0.05. Error bars = SEM.
