Figure 4From: EEGgui: a program used to detect electroencephalogram anomalies after traumatic brain injuryFirst 10 minutes of recording after injection of pentylene tetrazol (PTZ). The two high amplitude bursts near 4 and 7 min are seizures. These are detected as events with power increases in all frequency band. In contrast, following the second seizure ECoG events associated with sleep are detected in lower frequency bands.Back to article page
