The overarching goal of this event-related potential (ERP) study was to examine the effects of scopolamine on the dynamics of brain network activation using a novel ERP network analysis method known as Brain Network Activation (BNA). BNA was used for extracting group-common stimulus-activated network patterns elicited to matching probe stimuli in the(More)
The possibility of an altered susceptibility of the injured brain to central nervous system (CNS) oxygen toxicity was examined in awake rats. Moderate to severe closed head injury with diffuse axonal damage was produced in anesthetized rats by the fluid percussion method (2-2.5 atm), after which chronic EEG electrodes were implanted. Twenty-four hours(More)
The main manifestations of CNS oxygen toxicity are generalized tonic-clonic seizures. We tested the protective effect of 2 antiepileptic drugs, carbamazepine and ethosuximide, which are commonly used for the treatment of generalized seizures, on hyperbaric oxygen-induced convulsions. Rats implanted with chronic cortical electrodes for continuous EEG(More)
The novel glycine-prodrug anticonvulsant, milacemide (2-N-pentylaminoacetamide) (500 mg/kg), significantly increased (greater than 400% the seizure threshold induced by hyperbaric oxygen (4.5 atmosphere). This effect was significantly reduced by the selective inhibition of monoamine oxidase B by 1-deprenyl (2.0 mg/kg). 1-Deprenyl alone hardly affected the(More)
A decrease in brain GABA concentration has been implied as the cause of convulsions induced by hyperbaric oxygen (HOP). We therefore examined the influence of sodium valproate, an anticonvulsant and GABA transaminase inhibitor on HOP-induced convulsions in rats. The mean latency of occurrence of the first electrical discharge in the ECoG and the appearance(More)
