Figure 2.
Raw recordings and PSD results of SWD and SWD-like activity. The left side of the figure shows the EEG recordings (filtered in 1–40 Hz) of two examples of SWD-like activity developed in the left hemisphere and one example of mature SWD activity recorded previously. Each subsequent two rows belong to the same animal. The right side of the figure shows the PSD results. As shown for the first two animals, SWD-like activity peaks at approximately 1.5–1.75 Hz, but for the third animal, the SWD activity peaks at 6 Hz and is similar on both hemispheres. L, left hemisphere; R, right hemisphere.
