Hind-limb clasping in Cdkl5tm1.2Cogr/Cdkl5tm1.2Cogr mice

behavior/neurological
• in the home cage
• however, activity in a novel open arena is normal
• longer mean duration of high-amplitude bursts and lower frequency as detected by electroencephalographic (EEG) recordings
• however, mice exhibit normal spontaneous and induced seizure occurrences
• mice treated with kainic acid fail to exhibit an increase in dose-dependent low frequency EEG power unlike wild-type mice
• however, mice exhibit normal spontaneous and induced seizure occurrences

nervous system
• longer mean duration of high-amplitude bursts and lower frequency as detected by electroencephalographic (EEG) recordings
• however, mice exhibit normal spontaneous and induced seizure occurrences
• mice treated with kainic acid fail to exhibit an increase in dose-dependent low frequency EEG power unlike wild-type mice
• however, mice exhibit normal spontaneous and induced seizure occurrences

vision/eye
• decreased amplitude, but not latency, of the first positive wave
