PHOENIX, July 13, 2011 /PRNewswire/ -- With the 3D release of the final Harry Potter film this week, leading visual neuroscientists at Barrow Neurological Institute say 3D illusions not only provide great entertainment, but might also tell us a lot about how our brains function. Top researchers Susana Martinez-Conde, PhD, and Stephen Macknik, PhD, have spent years examining the correlation between vision and the brain. Recently they have teamed up with some of the world's best magicians,...

By taking advantage of a "body swap" illusion, researchers have captured the brain regions involved in one of the most fundamental aspects of self-awareness: how we recognize our bodies as our own, distinct from others and from the outside world. That self-perception is traced to specialized multisensory neurons in various parts of the brain that integrate different sensory inputs across all body parts into a unified view of the body. The findings, reported online on June 16 in Current...

Imagine shrinking to the size of a doll in your sleep. When you wake up, will you perceive yourself as tiny or the world as being populated by giants? Researchers at Karolinska Institutet in Sweden may have found the answer. According to the textbooks, our perception of size and distance is a product of how the brain interprets different visual cues, such as the size of an object on the retina and its movement across the visual field. Some researchers have claimed that our bodies also...

Max Planck scientists show how flexibly the brain processes images Our brains process many more stimuli than we become aware of. Often images enter our brain without being noticed: visual information is being processed, but does not reach consciousness, that is, we do not have an impression of it. Then, what is the difference between conscious and unconscious perception, and can both forms of perception be changed through practice? These questions are important not only for basic research,...

LA JOLLA, Calif., Feb. 18, 2011 /PRNewswire-USNewswire/ -- The Salk Institute for Biological Studies today announced a generous gift from Mr. Conrad Prebys, a Salk Trustee, to establish the Conrad T. Prebys Endowed Chair in Vision Research for Dr. Tom Albright. As part of their senior scientist endowed chair challenge, Joan and Irwin Jacobs will match the donor's gift with an additional $1,000,000 to establish the donor's named chair at $3,000,000. "This unique gift will help change the...

If you already know what you are about to see, you will recognise it faster The human brain works incredibly fast. However, visual impressions are so complex that their processing takes several hundred milliseconds before they enter our consciousness. Scientists at the Max Planck Institute for Brain Research in Frankfurt am Main have now shown that this delay may vary in length. When the brain possesses some prior information ̢蠫 that is, when it already knows...

Humans use their senses to help keep track of short intervals of time according to new research, which suggests that our perception of time is not maintained by an internal body clock alone. Scientists from UCL (University College London) set out to answer the question "Where does our sense of time come from?" Their results show that it comes partly from observing how much the world changes, as we have learnt to expect our sensory inputs to change at a particular 'average' rate. Comparing the...

How to look younger without plastic surgery? Psychologists of the Jena University (Germany) have a simple solution to this question: Those who want to look younger should surround themselves with older people. Because when viewing a 30-year-old we estimate his age to be much younger if we have previously been perceiving faces of older people. "People are actually quite good at guessing the age of the person next to them," Dr. Holger Wiese says. The psychologist of the Jena University is...

A brain area known to play a critical role in vision is divided into compartments that respond separately to different colors and orientations, Vanderbilt University researchers have discovered. The findings have important implications for furthering our understanding of perception and attention. The research was published Nov. 14, 2010, in Nature Neuroscience. "In vision, objects are defined by both their shape and their surface properties, such as color and brightness. For example, to...

(Ivanhoe Newswire) -- The brain can process sensory information in a fraction of a second, but in special cases it can be processed quicker.  A recent study from the Journal of Neuroscience found that those who are born blind can process tactile signals quicker than those with unimpaired vision. Daniel Goldreich, PhD and his research team at McMaster University tested the tactile aptitude of 89 non-blind subjects against 57 vision-impaired subjects by tapping each individual's index...
