Stage-dependent changes in beta and gamma burst rates in mPFC and BLA. (A) Overview of the burst detection procedure. Left: Anatomical regions of the mPFC and BLA. Middle: Raw LFP time traces for each region, with corresponding beta (20–30 Hz) and gamma (60–92 Hz) bursts marked on the filtered signals. Right: Summary of the burst detection algorithm, adapted from Cho & Choi12. (B) mPFC beta and gamma burst rates, averaged over all trials (n = 59), plotted against task time. The onset of the robot attack is indicated by a vertical dashed line. (C) mPFC beta (left) and gamma (right) burst rates averaged over the duration of each stage (1 min). The bar plots depict the mean burst rates, with their standard errors illustrated in gray error bars. Significant differences between stages are denoted by asterisks. Statistical significance was determined using the Friedman test, followed by the post-hoc Nemenyi’s test accounting for multiple comparisons. (D) The same analysis as in (B) is performed on the BLA data. (E) The same analysis as in (C) is performed on the BLA data. Throughout the plots, orange and green signify the beta and gamma bands, respectively. Significance levels are marked by *** for p < 0.001, ** for p < 0.01, and * for p < 0.05. The mouse head illustration and curved arrows in (A) are credited to Luigi Petrucco (https://scidraw.io/) and SANB (https://flatiocon.com/), respectively.
