seeing by the tongue

This technology has been in development for some time now and it appears it's about to be released. When you've read this you'll know as much as we do about it.Seeing with your tongue. By RON SEELY, 608-252-6131,rseely@madison.comRoger Behm lost his sight at 16, the victim of an inherited disease that destroyedhis retinas. Both of his eyes were surgically removed.Now 55, Behm has made himself at home in a sightless world. He started his own businessin Janesville selling devices that help the blind cope with day-to-day tasks. Heand his wife have raised five children and just adopted another child from Chinawho is also blind. He fishes, canoes, camps and scuba dives.But Behm can remember seeing. Which is why he couldn't believe it when, three yearsago, he slipped a device over his head, turned it on, and was once again able todiscern light and dark, shapes and shadows, letters and numbers, and even a rollinggolf ball."I could look down and and see the ball, white on black, and I could see myself swingingmy putter," Behm said. "And, of course, I missed. But I could reach down and pickup my ball, like any other sighted person."The device is called BrainPort and, though it seems like a gadget from Star Trek,it may be available commercially by the end of the year.It works by converting images from a video camera to electrical impulses that aretransmitted via the tongue to the brain of the blind person and turned again intoblack-and-white images that the user sees.It takes advantage of groundbreaking work by a UW-Madison scientist that showed thebrain will reprogram itself to accept and use different sensory signals - in thiscase touch instead of sight - to replace signals that can no longer be received dueto injury or disease.The device, which consists of a miniature camera mounted on a pair of sunglasses,a tongue sensor and a small control unit, was developed by Wicab of Middleton. Itbuilds on another of the company's devices that uses the same underlying ideas tohelp restore users' balance.The company is applying to the federal Food and Drug Administration to get approvalfor a marketable version of the vision device that could be available by the endof the year, Wicab CEO Robert Beckman said.Trying circumstances.Few have tested BrainPort under more trying circumstances than Erik Weihenmayer,the only blind man to reach the summit of Mt. Everest. Weihenmayer, totally blindsince the age of 16, has used the device to help him hike in the woods, even ascendclimbing walls. But he has most appreciated it for letting him do such simple butrewarding tasks as playing tic-tac-toe with his daughter or reaching down to pethis dog."I have a climbing friend who didn't believe me when I told him about this," Weihenmayersaid. "So he put a Pepsi can on my table in my kitchen while I was out of the room.Then he called me back in and told me to grab it. I reached out and grabbed the Pepsican. He was blown away. He was speechless. He had tears in his eyes."I mean, it may not seem like a real big deal to people, but to be able to see yourcoffee cup ... ."Neither Behm nor Weihenmayer are paid consultants to Wicab, although the companypays some of their expenses.The late Paul Bach-y-Rita, a UW-Madison physician and specialist in rehabilitation,first came up with the ideas that inspired BrainPort in the 1960s. The technologywas patented by UW-Madison in 1998, and commercial development has been under wayfor more than 10 years.New ways to work.Bach-y-Rita's earliest thinking about the brain's ability to adapt to new ways ofreceiving and processing information - its "plasticity," as it is known now - waslikely sparked by the dramatic struggle of his father, Pedro, to recover from a devastatingstroke in the mid-1960s, Beckman said.Neurologists in those days believed brain damage could not be reversed. But Bach-y-Rita'sbrother, George, soon put their father to work doing chores such as sweeping theporch of the house. Forced to accomplish more and more difficult tasks, their fathereventually recovered completely and even went back to his job teaching.He died at the age of 73 of a heart attack while climbing in the mountains of Columbia.Remarkably, studies of Pedro's brain after his death showed massive damage to hisbrain from the stroke. Yet he recovered. Somehow, his brain had found new ways towork.At the UW-Madison, Bach-y-Rita focused his studies on sensory substitution, the ideathat the brain can learn how to use other senses to replace one that has been lostor damaged. He concentrated on the power of touch, studying what happens in the brainwhen visual cues come from the sensitive nerves of the skin, such as those on thefingertips.Perfect organ.Those studies buttressed others that showed the brain can indeed learn how to usenerve impulses, delivered through touch, to create images. Exactly what happens remainssomewhat of a mystery. But more recently, MRI images taken of the brain while itis working do show the visual cortex of the brain lighting up when receiving sensorydata retrieved through touch."The information does get to the area of the brain that is responsible for vision,"said Kurt Kaczmarek, a UW-Madison engineer and scientist who was involved in theearly work on BrainPort.The tongue is the perfect organ for the task, Beckman said, because it is moist andan excellent transmitter of electrical signals, and it has more tactile nerve endingsthan any other part of the body except for the lips.Though one can read the science over and over again, it still requires somewhat ofa leap of faith to grasp the idea of "seeing" through the tongue. Simply, the patternsof light picked up by the camera are converted by a tiny computer into electricalpulses across 100 stainless steel electrodes. Users say it feels similar to touchinga weak battery to your tongue, a bubbly or tingling sensation.The pulses are spatially encoded, meaning the person receiving those signals on thetongue can perceive depth, perspective, size and shape. That information is translatedby the brain into images - fuzzy images, because of the low resolution, but imagesnonetheless. Those who have used the device explain that they perceive the objectsin front of them, separate from their own bodies.A milestone of sorts.Weihenmayer recalled how when he first tried BrainPort, the researchers sat him downat a table, fitted him with the device, and then rolled a ball toward him."It's a hard thing to wrap your brain around," said Weihenmayer. "But when they rolleda white tennis ball toward me, I could feel the ball rolling. First I could feelthe ball starting at the back of my tongue and getting bigger and bigger, comingtoward me. And then I reached out and grabbed it."When he ascends a rock climbing wall with BrainPort, Weihenmayer said, he can seethe handholds, their differences in shape and the contrast in light between themand the background. What he sees, he explained, is largely shapes and light variations,sort of an out-of-focus image.Last month, Weihenmayer joined Beckman at the National Eye Institute's 40th anniversarycelebration to demonstrate BrainPort and some of its powers. It seemed a milestoneof sorts.But the man whose genius led to the creation of such a useful invention was not present.Bach-y-Rita died of cancer in November of 2006."He would have loved to have been there," said Beckman.Source URL:http://www.madison.com/wsj/topstories/451

for mothers of hearing impaired children

Children suffering from hearing impairment need early identification and intervention for proper rehabilitation, which can be done best by the mother by becoming a link between rehabilitation professionals and the child, an audiology expert said on Sunday.
“Hearing is prerequisite for a child’s speech language development. This could be severely hampered in the absence of hearing ability. Here mothers can play a very important role. Mother spends the most time with the child. Hence she can identify the handicap in the child and approach professionals like ENT specialist or pediatrician for help,” Reader and Head, Department of Audiology, Ali Yavar Jung National Institute for the Hearing Handicapped, Rajeev R Jalvi told Sakal Times.
The national institute is an autonomous institute under the Ministry of Social Justice and Empowerment, Government of India, based in Mumbai. Jalvi was in the city to attend a programme on hearing disability organised by city-based NGO Cochlea Pune.
“As soon as the disability is detected, the child should be given a hearing aid. Then pictorial depiction of everyday activities and their physical imitation is the best way to teach the child. For example, regarding brushing teeth, mother should give a running commentary of the activity involving in the brushing activity explaining each action in detail and imitate it before the child. Then get the child repeat the process with her,” Jalvi said.
Similarly for animal or bird sounds, she should show pictures of the animal or bird or a film based on animals. Show the association between object and the sound by showing it and pronounce the sound, he said.
“It is the birthright of every child to get a hearing aid by six months of age. Parents should ensure that by the first birthday, the child is able to pronounce at least 10 to 15 words,” he said, adding the mother should also involve other family members in the rehabilitation process.
According to the National Sample Survey Organisation (NSSO) survey of disabled people in 2002, three million children were found hearing impaired between 0 to 4 years.
“This is a very high number. It signifies that society is not serious in finding a solution. There are 70 affected children born everyday in a district with 25 lakh population. There is 70 to 80 per cent delay in intervention due to lack of awareness and resources,” the expert said.

Hippocrates once said “Give me a fever and I can cure the child”. By understanding that a simple fever is a symptom rather than a condition orillness in itself, you soon come to realise that it is an ally and notan enemy. Fevers are the first sign that your child’s immune symptom isfunctioning as it should. By increasing core body temperature, feversenable the immune system to swing into action, indicating the body’sdefences are fighting an infection and consequent temperaturefluctuat ions indicate how the body is coping. - Natural Parenting.

AUTISM SPECTRUM DISORDER

AUTISM SPECTRUM DISORDER

FOR KIDS’ EYES ONLY

Ever wondered why:
Some children don’t answer when you talk to them.
Some children don’t talk at all, even though they are big and at school.
Some children talk only about dinosaurs or space.
Some children flap their hands or twirl around.
Some children play with string or other funny things.
Some children don’t go away even when you ask them to.
Some children walk round and round the playground all by themselves.

These children may have an Autism Spectrum Disorder (ASD).

What is Autism Spectrum Disorder?

An Autism Spectrum Disorder (ASD) occurs when a baby’s brain develops a little differently before or just after the baby is born. The brain then processes or interprets information differently.

People who have an ASD have difficulty communicating and learning how to be friends with other people. They often want things to be the same and may need to do things in exactly the same way every time.

People who have an ASD also sense things differently from many other people. Loud noises, like the school bell, can hurt their ears and they may not like the way certain things feel. They may like to stare at leaves moving in the trees but hate the swirling lights at the school disco. They may only want to eat exactly the same things or they may not like the way some food smells.

Is everyone who has an ASD just the same?

No. People who have an ASD are different from each other just like you and your friends are different.

Some people who have an ASD can talk, but they usually expect you to say exactly what you mean, if you say “Jump to it!” when you mean “Hurry up,” the child who has an ASD will probably start jumping.

Other people, who have an Autism Spectrum Disorder, use pictures or photographs to communicate with other people.

Some people who have an ASD can do their school work quickly, while other people find it difficult to learn to read and write. Some people who have an ASD want to be alone while others want to have friends, but don’t know how to make them.

There are different types of Autism Spectrum Disorder, which have different names; these include Autism and Asperger’s Syndrome.

Can I catch Autism Spectrum Disorder?

No. You can’t catch an Autism Spectrum Disorder like you catch a cold or chickenpox. People are born with an ASD. As they grow older many people who have an ASD learn to do lots of things just like you.

Will ASD go away?

No. An ASD is something that people have all their lives. However, as they grow they learn more and more about the world. Many people who have an Autism Spectrum Disorder will have a job and live independently when they grow up, just like you will.

How can I help someone who has an ASD?

Be nice and don’t tease.
Ask them to join in your games.
Sometimes people who have an ASD like it when you talk to them.
Speak clearly and don’t use too many big words.
Say what you mean.
Tell the person to take a step back if they come too close.
Remind the person that we only need to say things once.
Warn the person if there is going to be a loud noise.
People who have an ASD usually like to play with a few friends, they may
not feel comfortable in a large group.
Explain the rules of the game just before you start to play.
Understand that sometimes the person who has an ASD may need time alone.

Remember it’s OK to be different!
We all are!!

interesting tips


How to increase download speeds in firefoxFirefox is configured by default for dial-up speeds. If you have high speed internet access such as DSL or cable, you can change a few settings in Firefox and increase your download speeds. If you change the number of connections that Firefox uses to download, you will see a dramatic increas in your bandwidth. The larger the file you are downloading, the greater the speed will be, because more connections can be made to the server.1. Change Firefox connection setting by typing "about:config" in the address bar of Firefox.2. In the "Filter:" bar, type "persistent"3. You should now see two preference names with their values:network.http. max-persistent-
connections- per-proxy user set interger 4network.http. max-persistent- connections- per-server user set interger 24. Double click on each of the preference names. A window will pop-up allowing you to change the values for each. If you have cable or DSL use a number between 20 and 30!. Click OK.5.Restart Firefox and you will be able to download more files simultaneously and each file a lot faster.

health is welth

Researchers shed light on new heart condition AnergiaWashington (IANS): Researchers are shedding new light on a syndrome affecting nearly 40 percent of older adults with heart failure: anergia.Anergia, or lack of energy, is a newly delineated, criterion-based geriatric syndrome that is often overlooked or dismissed by doctors and patients alike as simply a natural tiredness associated with "old age".Whether anergia is a result of heart failure or perhaps a potential underlying contributing factor is not entirely clear.However, one thing is certain, researchers say: Fatigue has been shown to have independent long-term prognostic implications in patients with heart failure.Mathew Maurer, associate professor of clinical medicine at Columbia University Medical Centre (CUMC), is the senior co-author of the study.As part of the nine-month prospective cohort study, heart failure patients were provided an actigraph - a device worn on the wrist like a watch that was used to assess physical activity, energy expenditures and sleep by measuring and recording limb movement.Participants were instructed to wear it continuously on their non-dominant wrist for the nine months of the study.At baseline and at every three months for a total of four visits, each subject underwent a targeted physical exam including measurement of heart failure severity and distance walked during a six-minute hall walk as well as other mediating factors, said a CUMC release.An earlier study by Dr. Maurer showed that anergia may stem from many conditions, including heart and kidney dysfunction, arthritis, lung disease, anaemia and depression.These findings were published in the March 2009 edition of the Journal of Cardiac Failure.
