A brain area known to play a critical role in vision is divided into compartments that respond separately to different colors and orientations, Vanderbilt University researchers have discovered. The findings have important implications for furthering our understanding of perception and attention. The research was published Nov. 14, 2010, in Nature Neuroscience. "In vision, objects are defined by both their shape and their surface properties, such as color and brightness. For example, to...

The colorful Australian film "ËœStrictly Ballroom' has been used in a breakthrough scientific experiment to locate the color processing centre in the human brain. The unconventional method helped researchers at The Vision Centre to find regions of the brain that respond particularly strongly to color. Their work could in future help in the treatment of patients who have become color blind due to brain injuries or a stroke. "In non-human primates there's a proposed "Ëœcolor...

A chance discovery has led Australian scientists to question key assumptions about how our vision works. Their results show the brain is more flexible and versatile than the computer it is often likened to, and even may lead to new tests for blinding diseases such as glaucoma. Previously it was thought that the brain's ability to discern color depends on a specialized nerve "Ëœcolor channel', but now, say researchers from The Vision Centre and Sydney University, it appears some...

Researchers at Washington University School of Medicine in St. Louis have peered deep into the eye of the chicken and found a masterpiece of biological design. Scientists mapped five types of light receptors in the chicken's eye. They discovered the receptors were laid out in interwoven mosaics that maximized the chicken's ability to see many colors in any given part of the retina, the light-sensing structure at the back of the eye. "Based on this analysis, birds have clearly one-upped us in...

Researchers from the University of Washington and the University of Florida have used gene therapy to cure two adult monkeys of color blindness, successfully restoring full color vision to the animals. Scientists had previously believed it was not possible to manipulate the adult brain in such a way, and that adding new sensory information, such as the visual receptors necessary for perfect color vision, could only be done during the earliest years of life, when the brain is at its most...

The eyes of nocturnal bats possess two spectral cone photoreceptor types for daylight and colour vision. Reporting in the open-access, peer-reviewed journal PLoS ONE, scientists at the Max Planck Institute for Brain Research in Frankfurt and the University of Oldenburg have detected cones and their visual pigments in two flower-visiting species of bat. With electroretinographic recordings, they found an increased sensitivity to UV light in cone-stimulating light conditions. The researchers...

BEND, Ore., May 14 /PRNewswire/ -- WindowAlert announced today that it has sent technologically advanced window decals to 1600 Pennsylvania Avenue in Washington DC. The decals help prevent wild birds from striking windows. It is hoped that Michelle Obama and her children will set an example for the country by installing the decals on White House windows. WindowAlert is an environmental firm specializing in UV-reflective technology. The company manufactures window decals that...

The way nocturnal geckos perceive color could lead to better cameras and contact lenses, researchers in Sweden said. The geckos are among the very few creatures able to see color at night, said Lina Roth, a researcher at the Lund University. The key to the exceptional vision is a series of distinct concentric zones of varying refractive powers, Roth and her team said in a study published Friday by the Association for Research in Vision and Ophthalmology. The gecko's multifocal optical system...

Nocturnal geckos are among the very few living creatures able to see colors at night, and scientists' discovery of series of distinct concentric zones may lead to insight into better cameras and contact lenses. The key to the exceptional night vision of the nocturnal helmet gecko is a series of distinct concentric zones of different refractive powers, according to a study published in the Association for Research in Vision and Ophthalmology's peer-reviewed, online Journal of Vision. This...

New York University biologists have mapped the medulla circuitry in fruit flies, setting the stage for subsequent research on how color vision is processed. The work, which appeared in the journal Current Biology, will allow future scholarship to explore how color vision is processed in the optic lobe of the fruit fly Drosophila, providing a paradigm for more complex systems in vertebrates.The research was conducted by postdoctoral fellow Javier Morante and Professor Claude Desplan of NYU's...


Word of the Day
barratry
  • The offense of persistently instigating lawsuits, typically groundless ones.
  • An unlawful breach of duty on the part of a ship's master or crew resulting in injury to the ship's owner.
  • Sale or purchase of positions in church or state.
This word ultimately comes from the Old French word 'barater,' to cheat.
