2012
Amblyopia is a developmental disorder of the visual cortex that is often accompanied by strong suppression of one eye. We present a new technique for measuring and treating interocular suppression in patients with amblyopia that can be deployed using virtual reality goggles or a portable iPod Touch device.

Source: Elise S.D. Buki, Danielle N. Beatty, and Taylor D. Sparks, Department of Materials Science and Engineering, The University of Utah, Salt Lake City, UT The laser flash method (LFA) is a technique used to measure thermal diffusivity, a material specific property. Thermal diffusivity (α) is the ratio of how much heat is conducted relative to how much heat is stored in a material. It is related to thermal conductivity (), how much heat is transferred through a material due to a temperature...

Photolysis of caged compounds allows the production of rapid and localized increases in the concentration of various physiologically active compounds. Here, we show how to obtain patch-clamp recordings combined with photolysis of caged cAMP or caged Ca for the study of olfactory transduction in dissociated mouse olfactory sensory neurons.

ReAsH/FlAsH Labeling and Image Analysis of Tetracysteine Sensor Proteins in Cells

The biarsenical dyes FlAsH and ReAsH bind specifically to tetracysteine motifs in proteins and can selectively label proteins in live cells. Recently this labeling strategy has been used to develop sensors for different protein conformations or oligomeric states. We describe the labeling approach and methods to quantitatively analyze binding.
FAQs
Interocular competition determines which eye’s input dominates conscious vision at a given moment. In CFS, rapidly changing mask images repeatedly stimulate one eye while a slowly presented image enters the other, so the competing signals do not receive equivalent perceptual access. This arrangement lets researchers examine how visual information can be processed while its contribution to awareness remains limited.
The changing mask is important because it continually refreshes the competing stimulation rather than presenting a single static obstacle. Researchers can therefore manipulate image properties and presentation duration while observing whether the target becomes visible. These controlled changes help separate effects of stimulus content from effects of time and visibility when studying visual awareness.
By varying whether an image is visible or suppressed, investigators can compare neural or behavioral responses under different awareness conditions. The same framework supports questions about attention, perception, and binocular vision, including whether emotionally or behaviorally relevant information can be analyzed before it enters conscious experience in a controlled experimental setting.
A typical design presents rapidly changing images to one eye and a slowly presented image to the other. The researcher then varies image properties, presentation duration, or stimulus visibility and records the resulting perceptual or task-related response. Comparing conditions shows how changes in competition and visibility relate to visual awareness.
Stimulus visibility provides a key comparison between information available to conscious experience and information presented under suppression. Alongside image properties and presentation duration, it allows researchers to test whether responses differ when the same kind of visual input is more or less accessible. The resulting comparisons clarify links between visual processing and awareness.
CFS is useful for investigating binocular vision, attention, perception, and the neural mechanisms that allow visual information to reach conscious awareness. It also offers a controlled way to test emotionally or behaviorally relevant stimuli before conscious experience. These applications connect the technique’s manipulation of visibility with broader questions about how the brain selects and interprets visual information.
