nervous system
• spontaneous beginning in the second postnatal week (P10), especially during cage changing and handling
• during cage changing and handling
• mossy fibers in temporal lobe epilepsies often sprout aberrant recurrent synapses with dentate granule cells
• abnormal dispersion at P14 after the onset of seizures
• mossy fibers in temporal lobe epilepsies often sprout aberrant recurrent synapses with dentate granule cells
• at P14 after the onset of seizures, particularly in the hilus of the dentate gyrus
• following the onset of seizures
• mice exhibit ictal epileptic electroencephalogram abnormalities, often bilateral, compared with wild-type mice

growth/size/body
• between P10 and P14

behavior/neurological
• mice lack stomach contents at death and likely die of dehydration and/or starvation
• inactive by P14
• spontaneous beginning in the second postnatal week (P10), especially during cage changing and handling
• during cage changing and handling

adipose tissue
• lack of body fact at P14

mortality/aging
• mean lifetime of 16 days; no mice survive beyond P21
• mice lack stomach contents at death and likely die of dehydration and/or starvation
