Slow binocular rivalry in bipolar disorder.
BACKGROUND The rate of binocular rivalry has been reported to be slower in subjects with bipolar disorder than in controls when tested with drifting, vertical and horizontal gratings of high spatial frequency. METHOD Here we assess the rate of binocular rivalry with stationary, vertical and horizontal gratings of low spatial frequency in 30 subjects with bipolar disorder, 30 age- and sex-matc...
متن کاملHemispatial neglect.
The syndrome of hemispatial neglect is characterised by reduced awareness of stimuli on one side of space, even though there may be no sensory loss. Although it is extremely common, it has proven to be a challenging condition to understand, and to treat. New insights from detailed behavioural and anatomical studies in patients, as well as functional imaging in healthy individuals, have begun to...
متن کاملBinocular Rivalry
When two different images are shown, one to each eye, we don't always see a mix of the two. In cases when the images differ in atleast one attribute we may see only one image at a time and this alternates between the two images. (eg: Horizontal and vertical gratings differ in the direction of grating. When horizontal grating is shown to say right eye and vertical grating to left eye we see only...
متن کاملBinocular rivalry
What is binocular rivalry? In humans and animals with forward facing eyes, the two eyes provide views of the world that are only subtly different from one another. In each eye, the lens focuses light into a two-dimensional image on the retina. In normal vision, the disparity between the retinal images provides a stereoscopic cue to the third spatial dimension, depth. But when the eyes are prese...
متن کاملVisual hemispatial neglect, re-assessed.
Increased computer use in clinical settings offers an opportunity to develop new neuropsychological tests that exploit the control computers have over stimulus dimensions and timing. However, before adopting new tools, empirical validation is necessary. In the current study, our aims were twofold: to describe a computerized adaptive procedure with broad potential for neuropsychological investig...
