Correlation between intracranial EEG (iEEG) recording time and seizure frequency in 16 dogs with naturally occurring epilepsy. For continuous (24/7) ambulatory iEEG recordings, either the NeuroVista Seizure Advisory System (SAS) or the Medtronic Summit System RC+S were used. The data show that the longer the recording time, the higher the chance of detecting spontaneous seizures in epileptic dogs. Data are from Gregg et al. (68).
