A team of NYU/U.Rochester researchers found evidence that viewing any image for as little as 0.5 seconds causes an after-affect on visual neurons. This rapid adaptation helps the brain distinguish subtle differences in visual patterns, a critical component of normal visual perception.
New York University scientist Denis Pelli finds that the transition from grid to face in Close's paintings occurs at relatively short distances, revealing a size-dependent breakdown of shape perception. This challenges existing theories and credits Chuck Close with discovering this effect.
Researchers Randolph Blake and Sang-Hun Lee found that humans can group elements into objects based on subtle changes in timing. By analyzing the precise timing of motion in a dense array of pinwheels, viewers could distinguish synchronized groups from individual elements.
Researchers at Max Planck Institute found that moving objects appear slower through rod photoreceptors than cone photoreceptors, especially under low light conditions. This underestimation can lead to compensatory speeding-up, which may be fatal.
Researchers found that imagining visual stimuli activates short-term memory, lowering the threshold of brightness for visual perception. This phenomenon suggests separate neural mechanisms control short- and long-term visual memory, with imagination enhancing visual abilities.
A study by NIH scientists found that individuals with dyslexia exhibit no activation in the V5/MT brain area, which specializes in movement perception. This suggests trouble processing specific visual information and may contribute to reading disabilities characteristic of dyslexia.
