Neuroscientists develop stimulation glove for patients suffering from stroke-related impairments

Improving the sense of touch and motor skills without active training - what sounds impossible, does actually work. Neuroscientists at the Ruhr-Universität Bochum have developed a glove that uses weak electrical pulses to stimulate the nerve fibres that connect the hands with the brain.

Innovation leads to faster drug therapies, increased understanding of proteins on microscopic level

Membrane proteins are the "gatekeepers" that allow information and molecules to pass into and out of a cell. Until recently, the microscopic study of these complex proteins has been restricted due to limitations of "force microscopes" that are available to researchers and the one-dimensional results these microscopes reveal.

Unique approach to help discover how cell changes shape in response to topographies

Cells in the human body change shape as they crawl, split, or cling to other surfaces, but while the scientific literature is filled with examples of how cell shapes shift in response to things they touch, little is known about the rules that govern these changes. And there has been no high-throughput way to systematically test different topologies against different types of cells to optimize the surface of something like a medical implant.

Haptics improve outcomes in people with visual prosthetics

Normal vision is essentially a spatial sense that often relies upon touch and movement during and after development, there is often a correlation between how an object looks and how it feels. Moreover, as a child's senses develop, there is cross-referencing between the various senses. Indeed, where the links between the senses are not made, there may be developmental problems or delays. This should be taken into consideration when training new users of visual prosthetics, artificial retinas, or bionic eyes, suggest researchers in Australia.

Researchers use atomic force microscopy technique to read information encoded in gut lining

A new technique based on atomic force microscopy was developed at the Institute of Food Research to help 'read' information encoded in the gut lining.

Scientists map sensory nerves in mouse skin

Johns Hopkins scientists have created stunning images of the branching patterns of individual sensory nerve cells. Their report, published online in the journal eLife on Dec. 18, details the arrangement of these branches in skin from the backs of mice.

Skin vibrations convey information to the brain much the same way as auditory system

When you walk into a darkened room, your first instinct is to feel around for a light switch. You slide your hand along the wall, feeling the transition from the doorframe to the painted drywall, and then up and down until you find the metal or plastic plate of the switch. During the process you use your sense of touch to develop an image in your mind of the wall's surface and make a better guess for where the switch is.

Retinal reader helps blind to ‘see’ words

An implanted retinal prosthesis, consisting of an array of electrodes linked up to a video camera and wearable computer, allows blind patients to successfully “read” two-to-four letter braille words.

Researchers stream braille patterns directly into a blind patient's retina

For the very first time researchers have streamed braille patterns directly into a blind patient's retina, allowing him to read four-letter words accurately and quickly with an ocular neuroprosthetic device.

Direct Molecular Recognition technique can quantitate multiple DNA species

Researchers at UCLA and New York University have developed a method to detect sequence differences in individual DNA molecules by taking nanoscopic pictures of the molecules themselves.

MEPs sign written declaration in European Parliament for accessible labelling

A record-breaking number of MEPs have signed a written declaration in the European Parliament supporting accessible labelling. This marks an important milestone for blind and partially sighted people.

USC engineers to develop robot vision-based mobility aid for visually impaired people

For the visually impaired, navigating city streets or neighborhoods has constant challenges. And most such people still must rely on a very rudimentary technology-a simple cane-to help them make their way through a complex world.

Neuroscientists document deliberate control of touch sensations in human working memory

Neuroscientists of the Charité - Universitätsmedizin Berlin have now been able for the first time to document deliberate control of touch sensations in human working memory. It has been shown that the human brain can remember several touch sensations at the same time and consciously retrieve the touch if concentration is focused on these touches.

Stimulation of brain nerves accelerates learning

In a breakthrough that may aid treatment of learning impairments, strokes, tinnitus and chronic pain, UT Dallas researchers have found that brain nerve stimulation accelerates learning in laboratory tests.

Study: Visual cortex can dramatically change its function

When your brain encounters sensory stimuli, such as the scent of your morning coffee or the sound of a honking car, that input gets shuttled to the appropriate brain region for analysis. The coffee aroma goes to the olfactory cortex, while sounds are processed in the auditory cortex.

New study: Portion of brain responsible for reading doesn't require vision at all

The portion of the brain responsible for visual reading doesn't require vision at all, according to a new study by researchers from the Hebrew University of Jerusalem and France.

Stripe of Gennari in the blind may play greater role in processing tactile stimuli

The Stripe of Gennari develops even in those who are blind from birth and does not degenerate, despite a lack of visual input. This was discovered by Robert Trampel and colleagues from the Max Planck Institute for Human Cognitive and Brain Sciences using magnetic resonance imaging. This bundle of nerve fibers, which is approximately 0.3 mm thick, is not exclusively responsible for optic information.

University Hospitals receives $42 million for cancer care

Jane and Lee Seidman have donated $42 million to University Hospitals (UH) the largest gift in the Cleveland-based health system's history. In recognition of this unprecedented generosity, UH is naming the "Jane and Lee Seidman Cancer Center" in their honor.

Brain adapts to vision loss by increasing speed of tactile perception

People who are blind from birth are able to detect tactile information faster than people with normal vision, according to a study in the Oct. 27 issue of The Journal of Neuroscience.

Today's OpEds: Health reform and long-term care; Health care incentives; Reasons for optimism or repeal and replace?

Our system of long-term care does not provide adequate or coordinated human services and medical treatment for our growing aging population. … Thanks to a provision of the new health care law known as the Community Living Assistance Services and Supports program, tomorrow's continuum of care does not have to be so unforgiving. For the first time, a voluntary public insurance program will be available to help adults and families pay for long-term care services (Bruce Chernof, 7/23).
