Marlene Cimons, National Science Foundation Research helps understand how brain systems interact to carry out cognitive processes People not only use their eyes to see, but also to move. It takes less than a fraction of a second to execute the loop that travels from the brain to the eyes, and then to the hands and/or arms. Bijan Pesaran is trying to figure out what occurs in the brain during this process. "Eye-hand coordination is the result of a complex interplay between two systems...

University of Iowa University of Iowa researchers create most detailed molecular map of eye region associated with vision loss Understanding eye diseases is tricky enough. Knowing what causes them at the molecular level is even more confounding. Now, University of Iowa researchers have created the most detailed map to date of a region of the human eye long associated with blinding diseases, such as age-related macular degeneration. The high-resolution molecular map catalogs...

McGill University Health Centre An international research project, led by the Research Institute of the McGill University Health Centre (RI-MUHC) in Montreal, reports that a new oral medication is showing significant progress in restoring vision to patients with Leber congenital amaurosis (LCA). Until now, this inherited retinal disease that causes visual impairment ranging from reduced vision to complete blindness, has remained untreatable. The study is published today in the scientific...

Solving 100-year Mystery Of How Birds Sense Light
2014-07-09 03:18:09

Institute of Transformative Bio-Molecules (ITbM), Nagoya University Professor Takashi Yoshimura and colleagues of the Institute of Transformative Bio-Molecules (WPI-ITbM) of Nagoya University have finally found the missing piece in how birds sense light by identifying a deep brain photoreceptor in Japanese quails, in which the receptor directly responds to light and controls seasonal breeding activity. Although it has been known for over 100 years that vertebrates apart from mammals...

Neural Regeneration Research Researchers at the University of Birmingham, UK, led by Dr. Ben Scheven, Dr. Wendy Leadbeater and Ben Mead have discovered that stem cells isolated from the teeth, termed dental pulp stem cells (DPSC), can protect retinal ganglion cells (RGCs) from death following injury and promote regeneration of their axons along the optic nerve. RGC loss is the leading cause of blindness and can arise through traumatic injury or degenerative diseases such as glaucoma....

Built-in Biological Sunscreen Allows Mantis Shrimp To See The Reef In A Whole Different Light
2014-07-04 03:48:19

Cell Press In an unexpected discovery, researchers have found that the complex eyes of mantis shrimp are equipped with optics that generate ultraviolet (UV) color vision. Mantis shrimp's six UV photoreceptors pick up on different colors within the UV spectrum based on filters made from an ingredient other animals depend on as built-in biological sunscreen, according to research reported in the Cell Press journal Current Biology on July 3. "The mantis shrimp visual system contains six...

Research May Help Prevent Eye Injuries Among Soldiers

By K.C. Gonzalez, University of Texas at San Antonio Researchers at UTSA are discovering that the current protective eyewear used by our US armed forces might not be adequate to protect soldiers exposed to explosive blasts. According to a recent study, ocular injuries now account for 13 percent of all battlefield injuries and are the fourth most common military deployment-related injury. With the support of the U.S. Department of Defense, UTSA biomedical engineering assistant...

University of California - San Diego Some neurons turn to neighbors to help take out the trash It's broadly assumed that cells degrade and recycle their own old or damaged organelles, but researchers at University of California, San Diego School of Medicine, The Johns Hopkins University School of Medicine and Kennedy Krieger Institute have discovered that some neurons transfer unwanted mitochondria – the tiny power plants inside cells – to supporting glial cells called astrocytes...
