In addition to ongoing gamma oscillations, we also observed a prominent sensory-evoked response in the 15-40 Hz range that was largely limited to 0-100 ms following pip onset (Figure S2B). Activity in this pip-evoked band was distinct from slow and fast gamma on the basis of strong power-power correlations within bands but weak correlation between bands (Figure S2C). Likewise, neither slow nor fast gamma was as reliably phase-locked to the pip as the 15-40 Hz pip-evoked band (Figure S2B, D). Overall, these data suggests that there are at least three distinct bands of high frequency activity in the BLA: slow and fast gamma, and pip-evoked 15-40 Hz activity.
