|
• however, doxycycline treatment between E1 and P15 prevents seizures
• mice exhibit seizures of 3 to 21 episodes during 24 hours each lasting 15 to 40 seconds
• seizures occur mainly during periods of increased delta activity regardless of doxycycline treatment as adults to silence the transgene
• most seizures occur during the light period (resting-sleeping)
|
|
