Hind-limb clasping in Cdkl5^tm1.2Cogr/Cdkl5^tm1.2Cogr mice

behavior/neurological

limb grasping ( J:209635 )

♀

decreased locomotor activity ( J:209635 )

♀ • in the home cage

♀ • however, activity in a novel open arena is normal

seizures ( J:209635 )

♀ • 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

abnormal seizure response to inducing agent ( J:209635 )

♀ • 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
