PINE BROOK, N.J., July 30, 2012 /PRNewswire/ -- Vision Problems in infants and pre-verbal children are a challenge for ophthalmologists and optometrists to diagnose and manage. Many vision tests look at just the structure of the eye or require a verbal response which many children are either unable or unwilling to give. Dr. Sean Donahue and colleagues at Vanderbilt Eye Institute in Nashville, TN recently presented a poster, Visually Evoked Potential Detection of Amblyopia in the Clinic, at...

New understanding of how the brain processes information from inner ear offers hope for sufferers of vertigo If you have ever looked over the edge of a cliff and felt dizzy, you understand the challenges faced by people who suffer from symptoms of vestibular dysfunction such as vertigo and dizziness. There are over 70 million of them in North America. For people with vestibular loss, performing basic daily living activities that we take for granted (e.g. dressing, eating, getting in and...

(Ivanhoe Newswire) - A new technology might allow people who have almost completely lost the ability to move their arms or legs to write, by using their eyes. The eye-writing technology tricks the neuromuscular machinery into doing something that is usually impossible: to voluntarily produce smooth eye movements in arbitrary directions. Jean Lorenceau of Université Pierre et Marie Curie-Paris, was quoted as saying, "Contrary to the current belief, we show that one can gain...

[ Watch the Video ] A new technology described in the paper published online on July 26 in Current Biology, a Cell Press publication, might allow people who have almost completely lost the ability to move their arms or legs to communicate freely, by using their eyes to write in cursive. The eye-writing technology tricks the neuromuscular machinery into doing something that is usually impossible: to voluntarily produce smooth eye movements in arbitrary directions. "Contrary to the...

You're headed out the door and you realize you don't have your car keys. After a few minutes of rifling through pockets, checking the seat cushions and scanning the coffee table, you find the familiar key ring and off you go. Easy enough, right? What you might not know is that the task that took you a couple seconds to complete is a task that computers —— despite decades of advancement and intricate calculations —— still can't perform as efficiently as humans: the...

The Visually Impaired Reach For Objects In Space Using Device That Converts Images Into Music
2012-07-05 12:07:20

Research results reported in Restorative Neurology and Neuroscience Sensory substitution devices (SSDs) use sound or touch to help the visually impaired perceive the visual scene surrounding them. The ideal SSD would assist not only in sensing the environment but also in performing daily activities based on this input. For example, accurately reaching for a coffee cup, or shaking a friend's hand. In a new study, scientists trained blindfolded sighted participants to perform fast and...

Connie K. Ho for redOrbit.com Sight. Sound. Touch. These are just a few of the senses that the body has. This theme of senses was the subject of a recent study by neuroscientists from the California Institute of Technology (Caltech) who reported a relationship between touch and emotion via the brain´s primary somatosensory cortex. The findings, described in a recent issue of the Proceedings of the National Academy of Sciences (PNAS), were discovered by researchers Valeria Gazzola...

Researchers at the RUB and from Durham report Patients who are blind in one side of their visual field benefit from presentation of sounds on the affected side. After passively hearing sounds for an hour, their visual detection of light stimuli in the blind half of their visual field improved significantly. Neural pathways that simultaneously process information from different senses are responsible for this effect. "We have embarked on a whole new therapy approach" says PD Dr....
