FIG. 3. — Lateralized periodic discharges with attenuation. Upper panel: Electroencephalogram (30-sec epoch, low-frequency filter 0.5 Hz, high-frequency filter 100.0 Hz) showing lateralized periodic discharges with attenuation after lateral fluid-percussion injury. Electroencephalogram showed generalized polymorphic delta activity and lateralized periodic discharges in the contralateral anterior channel (C4). Lower panel: A heat map showing the same epoch, indicating lateralization. Note the intermittent increase in contralateral parietal (C4) fast activity. Color image is available online.
