behavior/neurological
• when this allele is inherited maternally, mice exhibit less freezing 24 hours after contextual fear conditioning compared to similarly treated wild-type mice
• when the allele is inherited maternally, mice exhibit impaired performance in a Morris water maze compared with wild-type mice
• when the allele is inherited maternally, mice exhibit impaired performance on a rotarod compared with wild-type mice
• when this allele is inherited maternally during waking periods when cortical bursts are observed unlike in wild-type mice
• when this allele is inherited maternally during waking periods when cortical bursts are observed unlike in wild-type mice
• when this allele is inherited maternally, mice exhibit increased waking and slow-wave sleep episode numbers compared to in wild-type mice
• when this allele is inherited maternally, mice exhibit reduced duration of slow-wave sleep episodes with increased waking at the dark/light transition compared with wild-type mice
• when this allele is inherited maternally, mice exhibit less of an increase in the amount of paradoxical sleep and unchanged slow-wave sleep amounts during recovery after a 4-hour sleep deprivation compared with wild-type mice
• 6 of 8 mice exhibit intermittent bursts of 4 to 5 Hz spike-wave discharged lasting 5 to 12 seconds unlike wild-type mice (J:75622)
• spike-wave discharges occur at variable frequencies, typically every 2 to 3 minutes, without behavior change (J:75622)
• 2 mice exhibited electrographic seizures without behavior change (J:75622)
• when this allele is inherited maternally, Purkinje cell simple spike spontaneous firing rate is higher than in wild-type mice (J:95305)
• however, spontaneous complex spike firing rate is normal (J:95305)
• when this allele is inherited maternally, one-sided peak counts of simple spike autocorrelogram are higher than in wild-type mice (J:95305)
• when this allele is inherited maternally, the rhythm index is higher than in wild-type mice (J:95305)
• when this allele is inherited maternally, mice exhibit spike-wave discharges during wake and slow-wave sleep periods unlike wild-type mice (J:102546)
