PURPOSE Whether febrile seizures have detrimental consequences on the brain is still controversial. We hypothesized that neuronal inhibition in the hippocampus is altered after hyperthermia-induced seizures in immature rats. METHODS Rats were given a single seizure by a heat lamp on postnatal day (PND) 15, or repeated seizures by heated air on PND 13 to(More)
BACKGROUND/PURPOSE Event-related potentials (ERPs) reflect higher cortical function and the P3 (P300) wave has been associated with various sensory, cognitive, and attention processes. The aims of this study were to understand the age-related change in ERPs in children between the ages of 6 and 13 years and to establish a normal reference value for(More)
OBJECTIVES Whether prolonged or complex febrile seizures (FS) produce long-term injury to the hippocampus is a critical question concerning the neurocognitive outcome of these seizures. Long-term event-related evoked potential (ERP) recording from the scalp is a noninvasive technique reflecting the sensory and cognitive processes associated with attention(More)
Consequences of seizures in the developing brain are not completely understood. The aim of this study was to investigate the long-term alterations of synaptic transmission and seizure susceptibility in the hippocampus after early-life seizures induced by systemic injection of a GABA(B)-receptor antagonist CGP56999A in immature rats. Experimental rats were(More)
BACKGROUND Recording of event-related potentials (ERPs) from the scalp is a noninvasive technique reflecting the sensory and cognitive processes associated with attention tasks. Attention deficit hyperactivity disorder (ADHD) is a disorder involving deficits in attention and behavioral control. The aim of this study was to investigate the difference in ERPs(More)
It has been shown that the blood-brain barrier (BBB) can be locally disrupted by focused ultrasound (FUS) in the presence of microbubbles (MB) while sustaining little damage to the brain tissue. Thus, the safety issue associated with FUS-induced BBB disruption (BBBD) needs to be investigated for future clinical applications. This study demonstrated the(More)
In a previous study, we reported a rat model of early-life limbic seizures which resulted in a loss of GABA(B) receptor inhibition in the hippocampus. Since gating of auditory evoked potentials in the hippocampus (auditory gating) requires GABA(B) receptors and spatial behaviors depend on the hippocampus, we hypothesize that rats with early-life limbic(More)
The ability to monitor the responses of and inhibit the growth of brain tumors during gene therapy has been severely limited due to the blood-brain barrier (BBB). A previous study has demonstrated the feasibility of noninvasive in vivo imaging with 123I-2'-fluoro-2'-deoxy-5-iodo-1-β-D-arabinofuranosyluracil (123I-FIAU) for monitoring herpes simplex virus(More)
