The details regarding the validation of this new device are published in the latest issue of Scientific Reports. Multifocal lenses are used in cataract surgeries – to replace the crystalline when it has lost its transparency – or to correct for presbyopia. There are different lens designs in the market, and choosing one or another […]Continue Reading ...
A large-scale systematic review of research into the accuracy of skin cancer diagnostics has found that visual inspection of suspicious lesions is insufficient to ensure an accurate diagnosis. iMoved Studio | Shutterstock The review, which has recently been published in The Cochrane Library, summarises a large body of research looking at the accuracy of tests […]Continue Reading ...
What we see is not only determined by what is really there, but also depends on whether we are paying attention, whether we are moving, excited or interested. In a new study published in Nature Communications, scientists from NERF (Neuro-Electronics Research Flanders) uncover that the processing of visual information in the brain is indeed modulated […]Continue Reading ...
One of the outstanding mysteries of the cerebral cortex is how individual neurons develop the proper synaptic connections to form large-scale, distributed networks. Now, an international team of scientists including researchers from Goethe University and the FIAS have gained novel insights from spontaneously generated patterns of activity by local networks in the early developing visual […]Continue Reading ...
A QUT journalism academic says the current freelancer-heavy market for media professionals could be preventing photographers and video journalists who report on traumatic news events from accessing the support they need. The results of TJ Thomson’s peer-reviewed study Mapping the emotional labor and work of visual journalism has been published in Journalism. “People understand exposure […]Continue Reading ...
Credit: CC0 Public Domain Even with an acute sense of hearing adults don’t always pick up exactly what someone has said. That’s because from childhood to adulthood we rely on vision to understand speech and this can influence our perception of sound. A study, carried out by Rebecca Hirst, a Ph.D. student in the School […]Continue Reading ...
Aug 22 2018 Even with an acute sense of hearing adults don’t always pick up exactly what someone has said. That’s because from childhood to adulthood we rely on vision to understand speech and this can influence our perception of sound. A study, carried out by Rebecca Hirst, a PhD student in the School of […]Continue Reading ...
July 31, 2018 A new study led by Carnegie Mellon University neuroscientists provides the first evidence of how the human brain recovers the ability to function after losing parts of the visual system. Published in Cell Reports, the researchers report on three years of behavioral and brain imaging tests on a nearly seven year-old boy […]Continue Reading ...
Nov 23 2018 Drummers and brass players are better able to judge the timing of visual stimuli than members of the color guard, according to a naturalistic study of the world-class drum corps Bluecoats published in eNeuro. This counterintuitive finding extends previous research demonstrating superior sensory learning and memory from cross-training the brain’s audio and […]Continue Reading ...
As the adage goes “neurons that fire together, wire together,” but a new paper published today in Neuron demonstrates that, in addition to response similarity, projection target also constrains local connectivity. Researchers from the Sainsbury Wellcome Centre have been looking to elucidate the rules of connectivity of neurons in the neocortex with the long term […]Continue Reading ...
Single neurons in the brain’s primary visual cortex can reliably detect straight lines, even though the cellular makeup of the neurons is constantly changing, according to a new study by Carnegie Mellon University neuroscientists, led by Associate Professor of Biological Sciences Sandra Kuhlman. The study’s findings, published in Scientific Reports on Oct. 16, lay the […]Continue Reading ...
New study highlights the role of attention as a component of vision restoration training in hemianopia About one third of patients who have suffered a stroke end up with low vision, losing up to half of their visual field. This partial blindness was long considered irreversible, but recent studies have shown that vision training after […]Continue Reading ...
August 13, 2018 A new University of Liverpool study, published in Wiley Brain and Behaviour, examines the factors that influence how a person adapts to visual field loss following stroke. Approximately 65% of acute stroke survivors have visual impairment which typically relates to impaired central or peripheral vision, eye movement abnormalities, or visual perceptual defects. […]Continue Reading ...
August 1, 2018 The boy suffered his first epileptic seizure at age four. Doctors tried medication and other treatments to control the seizures–the result of a low-grade brain tumor–but nothing worked. As a last resort, shortly before the boy’s seventh birthday, surgeons removed a third of the right hemisphere of his brain. In a case […]Continue Reading ...
