UCLA study shows brain's ability to reorganize
Visually impaired people appear to be fearless, navigating busy sidewalks and crosswalks, safely finding their way using nothing more than a cane as a guide. view more (2009-11-19)
Client-directed therapy technique drastically reduces divorce/separation rates
Using four simple questions to generate client-directed feedback can greatly increase the chances that struggling couples will stay together, according to a recently published study. view more (2009-11-16)
Study finds many people with hemianopia have difficulty detecting pedestrians while driving, advocates for individual testing
Schepens Eye Research Institute scientists have found that--when tested in a driving simulator--patients with hemianopia (blindness in one half of the visual field in both eyes) have significantly more difficulty detecting pedestrians (on their blind side) than normally sighted people. view more (2009-11-13)
Theory about long and short-term memory questioned by UCL scientists
The long-held theory that our brains use different mechanisms for forming long-term and short-term memories has been challenged by new research from UCL, published today in PNAS. view more (2009-11-10)
Mobile microscopes illuminate the brain
The majority of our life is spent moving around a static world and we generate our impression of the world using visual and other senses simultaneously. view more (2009-11-03)
Sight gone, but not necessarily lost?
Like all tissues in the body, the eye needs a healthy blood supply to function properly. Poorly developed blood vessels can lead to visual impairment or even blindness. view more (2009-11-02)
Clues to visual variant Alzheimer's; myopia and diabetic retinopathy risk
Two studies are of particular note in today's Scientific Program of the 2009 Joint Meeting of the American Academy of Ophthalmology (AAO) and the Pan-American Association of Ophthalmology (PAAO): a report by Swiss neuro-ophthalmic researchers about vision exam clues that should make ophthalmologists suspect an atypical variant of Alzheimer's... view more...

How white is a paper?
Whiter paper and better color reproduction are examples of important competitive advantages on an international market. view more (2009-10-23)
First in New York: Bionic technology aims to give sight to woman blinded beginning at age 13
A 50-year-old New York woman who was diagnosed with a progressive blinding disease at age 13 was implanted with an experimental electronic eye implant that has partially restored her vision. view more (2009-10-22)
Women outperform men when identifying emotion
Women are better than men at distinguishing between emotions, especially fear and disgust, according to a new study published in the online version of the journal Neuropsychologia. view more (2009-10-22)
Can we 'learn to see?': Study shows perception of invisible stimuli improves with training
Although we assume we can see everything in our field of vision, the brain actually picks and chooses the stimuli that come into our consciousness. view more (2009-10-22)
Time-Keeping Brain Neurons Discovered
Groups of neurons that precisely keep time have been discovered in the primate brain by a team of researchers that includes Dezhe Jin, assistant professor of physics at Penn State University and two neuroscientists from the RIKEN Brain Science Institute in Japan and the Massachusetts Institute of Technology (MIT). view more (2009-10-22)
Experimental treatments restore partial vision to blind people
Two experimental treatments, a retinal prosthesis and fetal tissue transplant, restored some vision to people with blinding eye diseases. The findings, presented at Neuroscience 2009, the annual meeting of the Society for Neuroscience and the world's largest source of emerging news on brain science and health, may lead to new treatments for the... view more...

Caltech scientists create robot surrogate for blind persons in testing visual prostheses
Scientists at the California Institute of Technology (Caltech) have created a remote-controlled robot that is able to simulate the "visual" experience of a blind person who has been implanted with a visual prosthesis, such as an artificial retina. view more (2009-10-20)
Researchers discover mechanism that helps humans see in bright and low light
Ever wonder how your eyes adjust during a blackout? When we go from light to near total darkness, cells in the retina must quickly adjust. Vision scientists at Washington University School of Medicine in St. Louis have identified an intricate process that allows the human eye to adapt to darkness very quickly. The same process also allows the eye... view more... (2009-10-14)
Dyslexia varies across language barriers
Chinese-speaking children with dyslexia have a disorder that is distinctly different, and perhaps more complicated and severe, than that of English speakers. view more (2009-10-13)
Noncorrectable vision problems associated with shorter lifespan in older adults
Visual problems that cannot be corrected are associated with increased risk of death among individuals between the ages of 49 and 74, and all visual impairments may be associated with the risk of death in older adults. view more (2009-10-13)
Cancer drug is no different in effectiveness as gold standard treatment for macular degeneration
Investigators from Boston University School of Medicine (BUSM) and the VA Boston Healthcare System have shown, at 6 months in a small group of patients, that there is no difference in efficacy between Bevacizumab (Avastin) and Ranibizumab (Lucentis) for the treatment of age-related macular degeneration (AMD). view more (2009-10-12)
Scans show learning 'sculpts' the brain's connections
Spontaneous brain activity formerly thought to be "white noise" measurably changes after a person learns a new task, researchers at Washington University School of Medicine in St. Louis and the University of Chieti, Italy, have shown. view more (2009-10-09)
The skinny on 'Lean' education
Educators should learn a thing or two from the Just-In-Time and Lean production techniques used by the automotive industry if they are to add value to the student experience as quickly and effectively as possible. view more (2009-09-28)
