Figure 2. Interictal spikes (IISs) coincide with high-frequency oscillations (HFOs) and population bursts.

Figure 2

(A) The LFP shows a sample IIS recorded in the frequency band of 1-500 Hz. (B) Filtering the LFP between 200-400 Hz shows a large increase in fast-ripple power during the negative peak of the IIS. (C) A raster of multiunit activity, aligned to the peak of all detected IISs (in this recording), shows a high degree of bursting during the IIS.
