  • After blindness, the adult brain can learn to see again October 26, 2016
    More than 40 million people worldwide are blind, and many of them reach this condition after many years of slow and progressive retinal degeneration. The development of sophisticated prostheses or new light-responsive elements, aiming to replace the disrupted retinal function and to feed restored visual signals to the brain, has provided new hope. However, very […]
  • Brain surface stimulation provides 'touch' feedback to direct movement October 26, 2016
    Grasping a cup or brushing hair or cooking a meal requires feedback that has been lost in amputees and individuals with paralysis -- a sense of touch. Researchers have now used direct stimulation of the human brain surface to provide this basic sensory feedback through artificial electrical signals, enabling a person to control movement while […]
  • Saving sight in glaucoma: Why the brain may hold the key October 26, 2016
    What causes vision loss in glaucoma? There are two common answers that at first may seem disparate: the first is pressure, as in elevated ocular pressure, and the second is damage to the optic nerve, which is the structure that sends visual information to the brain. Both answers are correct.
  • Easing labor pain may help reduce postpartum depression in some women October 26, 2016
    Epidural anesthesia may do more than relieve pain during labor; in some women it may decrease the likelihood of postpartum depression, suggests a preliminary study.
  • Additional benefit of omega-3 fatty acids for the clearance of metabolites from the brain October 26, 2016
    Omega-3 polyunsaturated fatty acids, which are found in fish oil, could improve the function of the glymphatic system, which facilitates the clearance of waste from the brain, and promote the clearance of metabolites including amyloid-? peptides, a primary culprit in Alzheimer's disease, report scientists.
