Supplementary Figure 2: Development of dmPFC and BLA 4-Hz oscillations during fear conditioning.
From: 4-Hz oscillations synchronize prefrontal–amygdala circuits during fear behavior
(a) Representative spectrogram of dmPFC LFPs recorded during auditory fear conditioning for successive CS+-US associations (top red lines: CS+ duration). White lines on the spectrogram indicate immobility/freezing episodes. (b, c) Averaged dmPFC (b) and BLA (c) power during CS+ presentations throughout the conditioning session (n = 4 mice, one way repeated measures ANOVA, dmPFC F(3,4) = 3.617, * P = 0.0372; BLA: F(3,4) = 4.794, * P = 0.0153). a.u.: arbitrary units. Spectral power in log scale. Error bars: mean ± s.e.m. For the representative example in (a), similar results were obtained for the 4 animals used in these experiments.
