A biophysical model of basolateral amygdala demonstrates that PV, SST, and VIP interneurons each contribute essential rhythm-generating roles (low/high theta and gamma); low theta (~3–6 Hz) emerges as a biomarker of successful fear conditioning via STDP-shaped fear circuits.

Here, we create a biophysically detailed model of the BLA circuit to show that several classes of interneurons (PV, SOM, and VIP) in the BLA can be critically involved in producing the rhythms; these rhythms promote the formation of a dedicated fear circuit shaped through spike-timing-dependent plasticity. We find that the low theta rhythm is a biomarker of successful fear conditioning.
