(a) Representative power spectrum of dmPFC LFPs recorded during Retrieval for freezing and no freezing periods. (b) Representative signal to noise ratio (SNR) of dmPFC 4 Hz oscillation (2-6 Hz) during Habituation (Hab.) and Retrieval (Ret.). (c) Representative power spectrum of BLA LFPs recorded during Retrieval for freezing and no freezing periods. (d) Representative signal to noise ratio (SNR) of BLA 4 Hz oscillation (2-6 Hz) during Habituation (Hab.) and Retrieval (Ret.). Similar results were obtained for the 13 animals used in these experiments.
