Study Gives Glimpse on How the Visual System Fills in the Gaps of What We See

"A Dartmouth College study sheds light on how the brain fills in the gaps of how we visually perceive the world around us. The findings appear in the journal Proceedings of the National Academy of Sciences," starts the Medical News Today post. "Visual images and other raw sensory data must reach the cerebral cortex to be perceived, but the data are often missing details when they are sent from the eyes to the visual cortex, the part of the brain responsible for seeing. Thus, our visual system regularly fills in extensive details to create enriched images that help us to understand and interpret what we see. A growing body of evidence suggests these 'filled-in' visual signals are represented at early stages of cortical processing. The researchers used fMRI on study participants to explore the neural mechanisms underlying the reconstruction of these 'filled-in' images. They found that 'intermediate' object features, which aren't in the retinal signals but are inferred during kinetic transformation, are reconstructed in neural responses at early stages of cortical processing, presumably via feedback from high-level brain areas."

Gene Therapy Might Restore Optic Nerve Function

"Research from Boston Children's Hospital suggests the possibility of restoring at least some visual function in people blinded by optic nerve damage from glaucoma... or from trauma," reports Medical News Today. "As reported online January 14 by the journal Cell, the scientists restored vision in mice with optic nerve injury by using gene therapy to get the nerves to regenerate and -- the crucial step -- adding a channel-blocking drug to help the nerves conduct impulses from the eye to the brain. In the future, they believe, the same effect could be achieved with drugs alone." Read more.

'"They asked, "Would you be interested in creating a piece of art from materials that we would send you?,"' said Wipfli. 'I agreed, and got a box in the mail that included lenses, frames‚ the side-bows to frames, their catalogues, promotional materials, old cases, sample lenses with different tints— all kinds of stuff. I was to make a sample piece in a month or two. After a few weeks, I got the email back saying I was one of the artists accepted.' For the next step, Wipfli had to transform his preliminary sample into a larger, more finished piece." Read more.

Vaccine for Vision Scourge Nearing Completion

"The world's first vaccine for a disease that causes misery for millions in Africa could be tested within five years," notes Medical News Today. "Researchers have taken a major step towards developing a vaccine against river blindness, also known as onchocerciasis, which affects an estimated 17 million people throughout the world. More than 90 per cent of cases of river blindness - listed by The World Health Organization as a neglected tropical disease - occur in west and central Africa. River blindness is a caused by infection with the parasitic worm Onchocerca volvulus and is spread by blackflies that breed in rivers." Read more.

Space Travel Provides Insights into Vision Problems

Medical News Today reports that "missions on board the International Space Station have revealed previously unreported effects of long-duration space flight on eyesight. Now, a study published in The FASEB Journal reports a new and significant finding in this area, as senior author Dr. Scott M. Smith, a researcher in the Biomedical Research and Environmental Sciences Division at NASA Johnson Space Center in Houston, TX, explains: "We've identified a genetic link in astronauts with vision issues." He and his colleagues discovered that two significant genetic differences can affect astronaut vision. The differences influence enzymes that direct an essential biochemical process in cells. Dr. Smith explains that while they have not identified the exact mechanism that leads to vision problems, their findings narrow down who to study and should hasten the search for the cause and how to treat the problem."

Contact Lens Solves a Murder Mystery

"On April 26, 2005, someone murdered 26-year-old Janet Abaroa, stabbing the young mother to death in her own home while her 6-month-old child slept nearby," starts the BuzzFeed story. "Her husband, Raven Abaroa, who had called 911, distraught, to report her death late that evening, quickly emerged as a suspect. His knife collection was suspiciously missing from the house, for one thing. A few months earlier, he had been caught embezzling from his employer. And he stood to benefit from his wife’s $500,000 life insurance policy.

"Abaroa had an alibi, however, and maintained his innocence. He was playing at an evening soccer game around the time of the murder, not long after his wife had been seen alive. And so the Durham, North Carolina, case went cold until five years later, when a Durham detective named Charles Sole went over the evidence one more time. Sole couldn’t get over one detail: When combing through the Abaroa house, investigators had never found Janet’s contact lenses. That was odd, because Raven Abaroa had claimed his wife was in bed watching TV when he left for the soccer game. And, as Janet’s friends and family told Sole and other investigators, taking out her contact lenses before watching TV was part of her nightly routine." Read mored.

High-Energy Demand for Eyes May Account for Its Vulnerability, Says NEI Study

"Our eyes are especially demanding when it comes to energy: Along with our brain, they require a substantial amount of power to keep them functioning and healthy. Now a new study by the National Eye Institute suggests that because of their high-energy demands, our eyes function at high efficiency and with little reserve capacity, which scientists say may explain why they become vulnerable to degenerative diseases." That's from a post from the NEI. Read more.
