U.S. scientists have found a widely held theory concerning the brain and perception is incorrect and that the brain blocks some information from awareness. Rutgers University researchers have discovered visual input obtained during eye movements is processed by the brain, but blocked from our awareness. The process of seeing requires the eyes to move so light can hit the photoreceptors at the center of each retina, which then pass that information to the brain, the scientists said. "If we...

Researchers find widely held theory on "Saccadic Suppression" is incorrect with discovery that the brain is blocking information from awarenessResearchers at the Center for Molecular and Behavioral Neuroscience (CMBN) at Rutgers University in Newark have identified the need to develop a new framework for understanding "perceptual stability" and how we see the world with their discovery that visual input obtained during eye movements is being processed by the brain but blocked from...

Motion illusions reveal new insights into perception In the classic waterfall illusion, if you stare at the downward motion of a waterfall for some period of time, stationary objects "” like rocks "” appear to drift upward. MIT neuroscientists have found that this phenomenon, called motion aftereffect, occurs not only in our visual perception but also in our tactile perception, and that these senses actually influence one another. Put another way, how you feel the world can...

When someone speaks to you, do you see what they are saying? We tend to think of speech as being something we hear, but recent studies suggest that we use a variety of senses for speech perception - that the brain treats speech as something we hear, see and even feel. In a new report in Current Directions in Psychological Science, a journal of the Association for Psychological Science, psychologist Lawrence Rosenblum describes research examining how our different senses blend together to help...

 Ever get a little motion sick from an illusion graphic designed to look like it's moving? A new study suggests that these illusions do more than trick the eye; they may also convince the brain that the graphic is actually moving.Researchers in Japan, led by Akiyoshi Kitaoka of Kyoto's Ritsumeikan University, monitored brain activity as participants viewed the Rotating Snakes illusion, where concentric circles appear to rotate continuously (see below). The resulting article, Functional...

Dollar signs for eyes "“ cartoonists have been drawing them for years, and the artists, while whimsical, may have been onto something. According to new research from UC San Diego, areas of the brain responsible for vision respond more strongly to objects of value.Led by John Serences, assistant professor of psychology and head of the Perception and Cognition Lab at UC San Diego, the study is published in the Dec. 26 issue of the Cell Press journal Neuron.Past rewards influence how...

Barrow scientists solve 200-year-old scientific debate involving visual illusions Neuroscientists at Barrow Neurological Institute at St. Joseph's Hospital and Medical Center have discovered a direct link between eye motions and the perception of illusory motion that solves a 200-year-old debate. Stephen Macknik, PhD, director of the Laboratory of Behavioral Neurophysiology; Susana Martinez-Conde, PhD, director of the Laboratory of Visual Neuroscience; Xoana G. Troncoso, PhD; and Jorge...

New research has found that learning the name of a color changes the part of the brain that handles color perception. Researchers reported infants perceive color in the right hemisphere of the brain, while adults do the job in the brain's left hemisphere. The change occurred when the toddlers learned the names to attach to particular colors. The scientists reported this in Tuesday's edition of Proceedings of the National Academy of Science. "It appears, as far as we can tell, that somehow the...

By Sparrow, Tom Sensation breaks up every system ... Emmanuel Levinas, Totality and Infinity It is both our panic and our privilege to be mortal and sense- full. We live on the leash of our senses. Although they enlarge us, they also limit and restrain us, but how beautifully. Diane Ackerman, A Natural History of the Senses When phenomenology turns to the body in its analyses of perception, it is seeking a way out of the tacit idealism which haunts its methodology. Carnal...

Mind trick yields new insights on perception Anyone who has seen an optical illusion can recall the quirky moment when you realize that the image being perceived is different from objective reality. Now, a team of scientists from MIT, Harvard and McGill has designed a new illusion involving the sense of touch, which is helping to glean new insights into perception and how different senses "” such as touch and sight "” work together. Ambiguous visual images are fascinating because...
