Between 1975 and 1989, 25 children treated with myelomeningocele closure and shunting for hydrocephalus at the Children's Hospital of Pittsburgh developed progressive lower brain-stem dysfunction from their Chiari malformation. Retrospective univariate and multivariate analyses of these cases were undertaken to assess the relationship between preoperative(More)
'Bursts' of high frequency (20-80 Hz) extracellular electrical activity are the signature of the brain mechanism mediating recognition of odors in rabbits and cats. To test the hypothesis that a similar mechanism may be functional in man outside the olfactory system, relationships were studied between bursts of 20-150 Hz scalp EEG and parameters of(More)
The clinical, neuroradiological, electrophysiological and CSF findings of seven patients with slowly progressive paraparesis or tetraparesis are presented. In all patients, the results of the tests performed, including evoked potentials, CT scanning, oligoclonal bands in the CSF and myelography, were normal or inconclusive and did not lead to the correct(More)
Using EEG data acquired during a simple (sRT) or choice (cRT) reaction time task we tested a signal enhancement technique. Our findings indicate that the signal enhancement technique under study substantially reduced background activity while retaining physiologically significant information. For each RT trial, a pre-stimulus epoch was modeled using a(More)
CATS is a collaborative European project promoting driverless vehicles that ended in December 2014. This contribution explains how the project evolved, including the handling of unexpected events and concentrating on lessons learned. The constructor and vehicle had to be changed for economic reasons in the middle of the project timeline. A second(More)
