Long-term EEG monitoring in chronically epileptic animals produces very large EEG data files which require efficient algorithms to differentiate interictal spikes and seizures from normal brain activity, noise, and, artifact. We compared four methods for seizure detection based on (1) EEG power as computed using amplitude squared (the power method), (2) the(More)
The development of acquired epilepsy after a perinatal hypoxic-ischemic (HI) insult was investigated in rats. After unilateral carotid ligation with hypoxia on postnatal day 7, cortical electroencephalographic and behavioral seizures were recorded with continuous radio-telemetry and video. Chronic recordings were obtained between 2 and 12 months of age in(More)
Hypoxic-ischemic (HI) encephalopathy is an important neurological problem of the perinatal period. Little is known of the long-term progression of HI insults or the maladaptive changes that lead to epilepsy. Using rats with unilateral carotid occlusion followed by hypoxia at postnatal day 7, this study provides an initial analysis of the epilepsy caused by(More)
BACKGROUND AND PURPOSE Notch receptors (1-4) are membrane proteins that, on ligand stilumation, release their cytoplasmic domains to serve as transcription factors. Notch-2 promotes proliferation both during development and cancer, but its role in response to ischemic injury is less well understood. The purpose of this study was to understand whether(More)
Rodents eliminate antiepileptic drugs (AEDs) faster than humans, creating challenges for designing clinically relevant protocols. Half-lives of AEDs in immature mice are unknown. The pharmacokinetics of commonly used AEDs were examined in CD1 mice using a single-dose protocol at postnatal day 19. After intraperitoneal therapeutic dosing, blood serum(More)
Intrauterine infection or inflammation in preterm neonates is a known risk for adverse neurological outcomes, including cognitive, motor and behavioral disabilities. Our previous data suggest that there is acute fetal brain inflammation in a mouse model of intrauterine exposure to lipopolysaccharides (LPS). We hypothesized that the in utero inflammation(More)
Stroke in term neonates remains a significant cause of long-term neurological morbidity. This study was designed to assess the relationships between ischemic stroke induced by permanent unilateral carotid ligation in P12 CD1 mice and the structural and functional outcomes in the young mice as a consequence. After P12 ischemic strokes, mice were behaviorally(More)
Neonatal stroke presents with seizures that are usually treated with phenobarbital. We hypothesized that anticonvulsants would attenuate ischemic injury, but that the dose-dependent effects of standard anticonvulsants would impact important age-dependent and injury-dependent consequences. In this study, ischemia induced by unilateral carotid ligation in(More)
Stroke in the neonatal brain frequently results in neurologic impairments including cognitive disability. We investigated the effect of long-term sodium valproate (valproate) and trichostatin A (TSA) treatment upon post-stroke neurogenesis in the dentate gyrus (DG) of stroke-injured immature mice. Decreased or abnormal integration of newborn DG neurons into(More)
Stroke is a major cause of neurologic morbidity in neonates and children. Because neonatal and pediatric stroke frequently present with seizures, the question of which anticonvulsant best blocks acute ischemic seizures and reduces injury is clinically relevant. The purpose of this study was to determine the extent to which gabapentin is neuroprotective and(More)
