20-25% of epileptic patients do not become seizure free on adequate drug therapy. In 25-50% of patients with intractable epilepsy, the brain area responsible for seizures is well localizable and does not involve eloquent regions. In these patients, the surgical excision of the epileptic focus may lead to relief from seizures. In Hungary, there may be 5-6000(More)
Backsourcing, defined generally as bringing services outsourced to a third party back in-house, is now a growing phenomenon. The decision to backsource has several significant implications for an organization, as it requires the organization to manage organizational change, reintegrate knowledge, and develop new capabilities and competences.

OBJECTIVE Reports on bilateral epilepsy surgical interventions are anecdotal because of the possible neurological deficits caused by them. METHODS We report on a four-year-old amaurotic child with catastrophic epilepsy due to bilateral occipital cortical dysplasia. After video-EEG monitoring and intraoperative electrocorticography he underwent a two-step(More)
This paper shows that cortical processing of information quantity can be given in bits, while speed of information processing can be given in bit/sec; therefore the information processing ability can be denoted in algebraical expression. Changes of emotional tension can be objectified by galvanic skin reflex and pulse reaction. This method and device is(More)
From July 1, 1994 to July 1, 1997 a total of 17 children with Chiari I malformation diagnosed by MRI was seen in our hospital. Six of them underwent craniocervical decompression and tonsilar resection. The major complaints of all these children were gait ataxia and persisting (longer than 6 month) headache, and one child had acutely presenting vertigo and(More)
The removal of the benign and only slightly symptomatic but by virtue of their localization potentially fatal lesions is a challenge for the neurosurgeons. Such cases demand a therapy without any postoperative morbidity. The neuroendoscopy meets these requirements and proves to be effective in more and more fields of the art. This article reports a case(More)
Conventional valve shunting for treatment of hydrocephalus has a high rate of long-term complication. After a brief historical review of neurosurgical endoscopy the authors present the different indications and methods of neuroendoscopy. Between 1995 and 1997 twenty-two pediatric patients underwent endoscopic surgery at National Institute of Neurosurgery.(More)
The 38-year period of human space exploration has gained for us a lot of experience in the problem of space motion sickness. The authors collected some causes of space sickness from the literature and from their research results. We collaborated with the Soviet-Russian space researchers and elaborated those vestibular research methods that were carried out(More)
