A synaesthesia-like effect in which people ‘hear’ silent flashes or movement, such as in popular ‘noisy GIFs’ and memes, could be due to a reduction of inhibition of signals that travel between visual and auditory areas of the brain, according to a new study led by researchers at City, University of London. The study is […]Continue Reading ...
Mar 27 2019 While there is increasing interest in using hallucinogenic drugs to treat conditions like depression and post-traumatic stress disorder, scientists are just beginning to understand what these drugs actually do in the brain—and how they cause hallucinations. In a study publishing March 26 in the journal Cell Reports, researchers looked at how a […]Continue Reading ...
Learning difficulties in schoolchildren are not always associated with visual problems, since they may be neurobiological or derived from other alterations such as dyslexia or attention deficit hyperactivity disorder (ADHD). This is the result of scientific work carried out by the University of Alicante Research Group in Optics and Visual Perception and a multidisciplinary team […]Continue Reading ...
Credit: public domain Monkey brain scans have revealed new information about the brain structure that processes visual information. The findings were recently presented in PNAS by neurophysiologists Qi Qhu (KU Leuven) and Wim Vanduffel (KU Leuven/ Harvard Medical School). When the brain receives visual signals from the eyes, it processes them in a strictly hierarchical […]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 ...
A new University study, published in PLOS ONE, highlights the high incidence and prevalence of visual problems in acute stroke survivors. A stroke is a serious life-threatening medical condition that occurs when the blood supply to part of the brain is cut off. The injury to the brain caused by a stroke can lead to […]Continue Reading ...
Credit: CC0 Public Domain How are the images cast on the retina reassembled in the brain? Researchers in Munich and Tuebingen find that processing of visual stimuli occurs at the earliest waystation on the way to the visual cortex—but not all inputs are treated equally. In humans, the visual system collects up to 80 percent […]Continue Reading ...
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 ...
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 ...
