Fourteen patients with severe bilateral carotid artery stenosis underwent carotid endarterectomy. Intra-operative ischemia was monitored by somatosensory evoked potentials (SSEP) bilaterally. Neuropsychological evaluations were completed within two days before operation and 4-9 days after operation. Complete loss of N1-P1 or P1-N2 components of the SSEP(More)
Of four patients having Angelman's syndrome admitted to a state mental facility who were clinically and electroencephalographically evaluated, 2 patients had CT scan studies of the brain. The most impressive and striking features that help in the diagnosis are the mental and physical retardation, nondevelopment of speech despite adequate visual and auditory(More)
Scalp recorded somatosensory evoked cortical responses (SSEP) may be measured under general anesthesia to assess the electrical responsiveness of the brain. Such potentials were measured in 25 patients undergoing carotid endarterectomy without shunt. Electrical unresponsiveness occurred bilaterally in one patient and unilaterally in one patient. The patient(More)

Selection of cutting patterns in order to minimize production waste is an important issue in operations research, which has attracted many researchers. Solving this problem is very important in the industries that have priorities in minimizing the waste in the Pages section. In this paper, the two-dimensional cutting stock problem has been studied to reduce(More)
We analyzed 320 electroencephalograms done on 60 patients having tuberous sclerosis. The main features in EEGs were diffuse slowing in the background activity, slow spike-wave discharges, focal and multifocal spike discharges, and amplitude asymmetries. No significant changes occurred in EEGs during the follow-up. No characteristic pattern was identified(More)
A woman having common migraine attacks coincident with an asymmetrical bilateral occipital lobe infarction that spared the brainstem and cerebellum underwent these studies: serial electroencephalography, brainstem auditory, visual and somatosensory evoked potentials, magnetic resonance imaging of the brain and cerebral arteriography. The patient's vision(More)
