Figure 4. An episode of paradoxical sleep during which (b) a long (13 s) spike-wave burst occurred. In a and c normal periods of paradoxical sleep, with eye and rostrum movements and theta waves that characterize this phase of sleep. During the seizure, small rostrum and wider eye movements were present. Notice that in the basolateral nucleus of the amygdala theta waves are typical of desynchronized sleep, despite the seizure in neocortical and hippocampal sites.
