we compare performance of adaptive schemes which are based on radial-basis functions and kalman filters for fast extraction of auditory evoked potentials. moreover, we propose a new method based on evoked potential modeling in the kalman filter framework, which can improve the accuracy compared to the existing methods. simulation results show that adaptive schemes and the kalman method are not ...

Background: Visual, brain stem auditory and somatosensory evoked potentials (EPs) have been traditional paraclinical tests to evaluate the competency of sensory tracts in multiple sclerosis (MS) patients. It seems that only one of these EPs could be sufficient, at least as a screening test. The objective of this paper is to evaluate the frequency of these three evoked potentials in definite MS ...

the clinical and phenotypic features of two siblings (a 12 years old girl and her 7 year old brother) with cockayne syndrome are described. the main problems were mild to moderate mental retardation, dwarfism, clumsy gait, photosensitive skin lesions and progeroid (senile like) appearance. brain ct - scans revealed symmetrical, well defined areas of calcification mainly located at lenticular nu...

We recorded regional cerebral blood flow, somatosensory evoked potentials, and auditory evoked potentials in the thalamic relay nuclei (ventral posterior lateral nucleus and medial geniculate body) and in the somatosensory and auditory cortices during and after 1 hour of transient left middle cerebral artery occlusion in nine cats. Regional cerebral blood flow was also measured in the thalamoco...
