fast gamma band within the BLA is preferentially coupled to mPFC theta input, and that this input is strongest during periods of safety. Periods of threat, by contrast, are associated with increased coupling to locally recorded theta. It is unclear from our data whether slow gamma in the BLA has a different input preference or behavioral analog compared to fast gamma. Nonetheless, both the HPC and BLA appear to dynamically switch between different gamma frequency modes, mediating input selection.
