9 years old, epilepsy. 

The patient is asleep. The 3 images above represent the same page on different montages. The 14 Hz version of 14- and 6-Hz positive bursts has been highlighted on the top page by the three horizontal red lines. Additionally, there is a right mid-temporal spike (arrowed). Notice the morphology of the 14- and 6-Hz positive bursts, their location, and their variable appearance over the posterior temporal regions.
