Visual neglect and extinction are well-known effects of lesions in the right hemisphere. This study shows that even with minor or no clinical signs of these deficits, and in the stable phase of recovery, asymmetric visual perception is common after right side lesions. Whole, partial and colour report experiments were used to estimate psychophysical parameters related to visual capacity and atte...

In this review we illustrated the case of a woman who had perimenstrual exacerbations of Darier-White disease. The disease improved markedly with the use of continuously administered oral contraceptives. This striking improvement without side-effects supports the use of oral contraceptives in women with Darier-White disease, although its role should be investigated further using controlled stud...

BACKGROUND White matter fiber tracts, especially those interconnecting the frontal and temporal lobes, are likely implicated in pathophysiology of schizophrenia. Very few studies, however, have focused on the fornix, a compact bundle of white matter fibers, projecting from the hippocampus to the septum, anterior nucleus of the thalamus and the mamillary bodies. Diffusion Tensor Imaging (DTI), a...

BACKGROUND AND PURPOSE Secondary-progressive MS is characterized by reduced acute inflammation and contrast enhancement but with increased axonal degeneration and cognitive/clinical disability that worsens with advanced disease. Relative recirculation, extracted from DSC is a surrogate measure of BBB integrity. We hypothesized that normal-appearing white matter relative recirculation is reduced...

The history of stellar seismology suggests that observation and theory often take turns advancing our understanding. The recent tripling of the sample of pulsating white dwarfs generated by the Sloan Digital Sky Survey represents a giant leap on the observational side. The time is ripe for a comparable advance on the theoretical side. There are basically two ways we can improve our theoretical ...

introduction: to compare the effects of 0.05% sodium fluoride (naf) mouthrinse, gc tooth mousse and gc mi paste plus on white spot formation inhibition. materials and methods: thirty pairs of extracted human premolars were cut in half mesio-distally with a disc. the teeth were coated with nail varnish, except a part of the buccal and/or lingual enamel, which was used as the test area, and then ...

Many useful test case construction methods that are based on important aspects of the specifcation have been proposed in the literature. A comprehensive test suite thus obtained is often very large and yet is non-redundant with respect to the aspects ident$ed from the specif cation. This paper addresses the problem of selecting a subset of test cases from such a test suite. We propose the use o...

We present a novel ‘dazzle’ illusion, in which black/white negative bar embedded grating and viewed near peripheral vision can look doubled, as if there were two bars lying side by touching each other.

The original q-Markov Covariance Equivalent Realization (q-Markov Cover) method for identification required white noise test signals, which can not be generated exactly. This paper replaces the unrealizable white noise signal with a realizable signal (the Pseudo Random Binary Signal (PRBS)), and proves that when the period of the PRBS approaches infinity the q-Markov Cover algorithm, operating ...
