FIG. 4.

Generalized periodic discharges. Upper panel: Electroencephalogram (30-sec epoch, low-frequency filter 0.5 Hz, high-frequency filter 100.0 Hz) showing generalized periodic discharges after lateral fluid-percussion injury. No clear ictal behavior was associated with the activity. Lower panel: A heat map showing the same epoch, indicating periodicity. Note the generalized (C3, C4, O1, O2) intermittent activity, followed by attenuation. For a longer period of periodic discharges, see Supplementary Video S2. Color image is available online.
