In the present study, we have validated the cortical potential imaging (CPI) technique for estimating cortical potentials from scalp EEG using simultaneously recorded electrocorticogram (ECoG) in the presence of strong local inhomogeneity, i.e., Silastic ECoG grid(s). The finite element method (FEM) was used to model the realistic postoperative head volume(More)
Invasive EEG monitoring is one of the best tools available for localization of epileptogenic foci in the brain. However, published data in mixed series of adult and pediatric patients show high incidence of epidural bacterial contamination, cerebrospinal fluid leakage, and skin infection after subdural electrode implantation. We sought to determine whether(More)
In some cognitively delayed children who require a vagal nerve stimulator for treatment of their seizures, there is a risk of wound breakdown and infection from obsessive tampering with the wound. We describe the interscapular placement of the vagal nerve stimulator pulse generator as a method to reduce this risk.
Brainstem auditory evoked responses (BAERs) were measured in pediatric patients with neurologic diseases. Abnormalities of interwave intervals, amplitude ratios, and response to changing rate of stimulation were found in patients with tumors, myelin disorders, anoxic-ischemic encephalopathy, trauma, and neurodegenerative disorders. Reversibility of(More)
The purpose of this paper is to demonstrate feasibility of using trends in Kolmogorov entropy to anticipate seizures in pediatric patients with intractable epilepsy. Surface and intracranial recordings of preseizure and seizure activity were obtained from five patients and subjected to time series analysis using Kolmogorov entropy. This metric was compared(More)
The antiepileptic drug felbamate has demonstrated efficacy against a variety of seizure types in the pediatric population, particularly seizures associated with Lennox-Gastaut syndrome. Postmarketing experience, however, revealed serious idiosyncratic adverse effects not observed during clinical trials, including aplastic anemia and liver failure. As a(More)
A consecutive, retrospective analysis of seizure control and quality of life was performed among 83 pediatric patients undergoing epilepsy surgery at Children's Hospital of Wisconsin. Seizure outcomes were generally favorable, with 68.7% class I outcomes; class II, 12%; and class III, 19.3%. Seizure freedom was highest among temporal lobectomies (84.2%) and(More)
OBJECTIVE To determine the accuracy of locating subdural electrodes by means of 3-D surface rendering of CT scans. METHODS Open source software has been developed and posted on the web which segments the electrodes into 3-D surfaces and allows their 3-D locations to be exported to other EEG analysis programs. The accuracy of the technique was determined(More)
The purpose of this paper is to illustrate the value of the brain stem auditory evoked response in the definitive assessment of newborn and older infants with congenital malformations of the auditory system. Clinical cases selected illustrate the methodology required in the evaluation and demonstrate how the technique can facilitate immediate and(More)
