A considerable body of psychophysical literature indicates that the context in which a stimulus occurs can have striking effects on its appearance. In particular, one group of lines can distort the perceived orientation of other lines, as many figural illusions show. This suggests an orientation-selective interaction among contourdetecting cortical units 6,15. By surrounding the receptive field...

Several observations suggest impaired central sensory integration in dystonia. We studied median and ulnar nerve somatosensory evoked potentials (SEPs) in 10 patients who had dystonia involving at least one upper limb (six had generalized, two had segmental and two had focal dystonia) and in 10 normal subjects. We compared the amplitude of spinal N13, brainstem P14, parietal N20 and P27 and fro...

BACKGROUND The microbial conversion of plant biomass into value added products is an attractive option to address the impacts of petroleum dependency. The Gram-negative bacterium Escherichia coli is commonly used as host for the industrial production of various chemical products with a variety of sugars as carbon sources. However, this strain neither produces endogenous cellulose degradation en...

Spinal SEP; N13; Cervical Radiculopathy Abstract Introduction: Most studies on somatosensory evoked potentials (SEPs) in cases of cervical radiculopathy routinely analyze scalp (cortical) responses (mixed or dermatomal SEPs), depending mainly on evaluation of N20 whose origin is the primary somatosensory cortex. It was suggested that selective study of the N13 potential, might be a useful techn...
