Encoding of fear and safety is also believed to engage circuits in the mPFC and HPC, which are highly interconnected and synchronized with the BLA (Lesting et al., 2011). A critical property of gamma oscillations is that they can be tightly synchronized between structures with near zero phase lag, even across long distances (Buzsáki and Wang, 2012). Such tight phase synchrony is suggested to allow for precise temporal coding despite long conduction delays (Buzsáki and Wang, 2012).
