Dragonflies May Help Improve Robotic Vision Systems
2013-08-16 04:47:12

[ Watch the Video: Dragonflies Hunt Food Like Humans ] April Flowers for redOrbit.com - Your Universe Online What do a dragonfly and a robot have in common? Nothing yet, but researchers at the University of Adelaide have discovered a novel and complex visual circuit in a dragonfly’s brain that might someday help to improve vision systems for robots. The underlying processes of insect vision have been the research subject for Dr Steven Wiederman and Associate Professor David...

Scientists working at the Research Center on Aging at the Health and Social Services Centre — University Institute of Geriatrics of Sherbrooke (CSSS-IUGS) have been studying strategies for protecting retinal pigment epithelium (RPE) cells. Dysfunction of the RPE is found in retinopathy and age-related macular degeneration, which is the leading cause of blindness of elderly people in developed countries. Findings published today in the Canadian Journal of Physiology and Pharmacology...

Animal study reveals “unexpected” role of horizontal cells in photoreceptor rod and cone cell development of retina Scientists are developing a clearer picture of how visual systems develop in mammals. The findings offer important clues to the origin of retinal disorders later in life. In research published this week in the Journal of Neuroscience, University at Buffalo scientists and colleagues focused on a particular protein, called a transcription factor, that regulates gene...

Red Lights At Night Better Than White When It Comes To Mood
2013-08-07 11:32:35

Brett Smith for redOrbit.com - Your Universe Online People working the graveyard shift may want to literally see red because according to a new study -- the color of light animals are exposed to at night can affect mood regulation. Study researchers from The Ohio State University found hamsters that were exposed to blue lights at night experienced the worst mood disruptions, followed closely by white lights, when compared to hamsters that spent their nights in a dim red light. "Our...

For Your Eyes Only: Understanding How Sight Evolved
2013-07-29 12:19:33

Brett Smith for redOrbit.com - Your Universe Online The ability to look out for predators or see a distant source of water has allowed humans to get where we are today, but how did our sense of vision evolve throughout time? In a newly published research review, Trevor Lamb, a neuroscientist at the Australian National University, decided to look into several questions surrounding the evolution of the human eye. "There are profound questions about the eye which are still not easy to...

The ability to pay attention to relevant information while ignoring distractions is a core brain function. Without the ability to focus and filter out "noise," we could not effectively interact with our environment. Despite much study of attention in the brain, the cellular mechanisms responsible for the effects of attention have remained a mystery... until now. In a study appearing in the journal Nature, researchers from Dartmouth's Geisel School of Medicine and the University of...

Starfish Have Primitive Eyes Used To Navigate Their Environment
2013-07-05 09:01:37

Society for Experimental Biology A study has shown for the first time that starfish use primitive eyes at the tip of their arms to visually navigate their environment. Research headed by Dr. Anders Garm at the Marine Biological Section of the University of Copenhagen in Denmark, showed that starfish eyes are image-forming and could be an essential stage in eye evolution. The researchers removed starfish with and without eyes from their food rich habitat, the coral reef, and placed them...

Diopsys VEP technology indicates functional abnormalities in early glaucoma patients where visual field testing fails. Pine Brook, NJ (PRWEB) June 28, 2013 To better evaluate patients with degenerative vision problems, a team of researchers from New York Eye and Ear Infirmary recently concluded that the Diopsys® NOVA-LX VEP vision test may be useful for diagnosis of glaucoma with structural abnormalities where visual field tests indicate normal vision. The outcome of their study...

Rat's Move Their Eyes In Opposite Directions When Running For Unique View
2013-05-28 14:17:27

Lee Rannals for redOrbit.com — Your Universe Online Max Planck Institute (MPG) scientists have found that rats move their eyes in opposite directions in both the horizontal and the vertical plane when running. This gives the rats a unique perspective on the world around them. The team discovered that each rat eye moves in a different direction, depending on the change in the animals' head position. They analyzed both eyes and found that one of the eye movements exclude the...
