We studied the organization of the somatosensory cortex in proficient Braille readers, recording somatosensory evoked potentials (SEPs) in 10 subjects and using transcranial magnetic stimulation (TMS) in five subjects, and compared the results with those of 15 control subjects. Somatosensory evoked potentials were elicited by a focal electrical stimulus to(More)
We describe an EEG pattern in pediatric sleep records, called the frequency-amplitude gradient (FAG). This pattern is a progressive decrement in voltage from occipital to frontal areas, with an accompanying decrease in slow frequencies in the same posterior-anterior direction. We report the results of examining 100 sleep records of children between birth(More)
We correlated the postresection electrocorticograms (ECoGs) of 80 patients who underwent temporal lobectomy under general anesthesia for treatment of intractable complex partial seizures with surgical results in three groups: seizure/aura free (32 patients), auras only (16 patients), and one or more postoperative seizures (32 patients) at mean follow-up(More)
The pattern of occipital-posterotemporal spike-wave paroxysms (O-PT SWPs), is a distinctive EEG abnormality observed primarily with occipital epilepsy of childhood and basilar artery migraine. We studied EEG and clinical features in 30 children and young adults with this EEG pattern. Prolonged and brief O-PT SWPs were observed. Prolonged discharges (greater(More)
A model of risk potential for developmental outcome was created based on cardiac, medical, surgical, and family-stress factors in 31 children with transposition of the great arteries who had undergone reparative open heart surgery utilizing cardiopulmonary bypass during infancy. Impact of these potential risk factors was assessed by 4 current neurologic(More)
Event-related potentials were recorded over occipital and parietal scalp from 20 patients suffering from intractable partial complex seizures prior to undergoing a temporal lobectomy. Subjects were presented with language and nonlanguage visual stimuli using a divided-field, "odd-ball" paradigm. Although behavioral performance (button-press accuracy,(More)
The EEGs of 98 elderly volunteers were compared with those of 84 patients with a recent cerebral infarction who had achieved a stable clinical course. All subjects were uniformly evaluated according to a special protocol. The elderly volunteers were accepted for the study if they had no history, signs or symptoms of central nervous system disease. The EEGs(More)
