|
behavior/neurological
|
• spontaneous high-voltage spikes and absence-like seizures
• no generalized tonic-clonic epilepsies
• less frequent than in triple knockout mice (Dbptm1Schb/tm1Schb, Hlftm1Schb/tm1Schb, Teftm1Schb/tm1Schb)
|
nervous system
|
• spontaneous high-voltage spikes and absence-like seizures
• no generalized tonic-clonic epilepsies
• less frequent than in triple knockout mice (Dbptm1Schb/tm1Schb, Hlftm1Schb/tm1Schb, Teftm1Schb/tm1Schb)
|
behavior/neurological
|
• several seizure-like activities are observed in mutants, however they never develop into generalized epilepsies
|
|
• several absence-like seizures without any sign of EEG hypoactivity are seen
|
nervous system
|
• several seizure-like activities are observed in mutants, however they never develop into generalized epilepsies
|
|
• several absence-like seizures without any sign of EEG hypoactivity are seen
|
|
• analysis of sleep EEG of a 12-hour light period shows an increase in slow-wave delta activity and a decrease in theta activity, however this is much less pronounced than in triple homozygous mutants
• activity in all frequency bins greater than 15 Hz (the beta frequency range) is increased in waking mutants
|
cardiovascular system
liver/biliary system
mortality/aging
|
• 50% of mice die within the first 2 months of age due to lethal seizures
|
behavior/neurological
|
• mice are hypersensitive to xenobiotic compounds including pentobarbital
|
|
• a circadian trend of seizure occurance is observed, with 4-times more seizures occuring during early light period hours (major sleep period) than during early dark period hours (major active period)
|
|
• observed in some mice; audiogenic seizures account for about 25% of all deceased mice
|
|
• spontaneous tonic-clonic seizures that occur predominantly within slow-wave sleep during the first 2 min after transition to sleep
|
|
• observe a few absence-like seizures without any sign of EEG hypoactivity

|
|
• reduction in levels of serotonin and dopamine and increase in levels of histamine in the brain
|
|
• analysis of sleep EEG of a 12-hour light period shows a significant increase in slow-wave delta activity and a significant decrease in theta activity
• activity in all frequency bins greater than 15 Hz (the beta frequency range) is significantly increased during all vigilance states
