She swears she’d remember that face forever. Then DNA evidence shows she’s got the wrong guy. It happens so frequently that many courts are looking with extreme skepticism at eyewitness testimony. http://medicalxpress.com/news/2011-12-accurate-memory-eyes.html Psychology & Psychiatry Mon, 05 Dec 2011 05:49:59 EST news242286568 Structures in the midbrain that developed early in evolution can be responsible for functions in newborns which in adults are taken over by the cerebral cortex. New evidence for this theory has been found in the visual system of monkeys by a team of researchers from the RUB. The scientists studied a reflex that stabilizes the image of a moving scene on the retina to prevent blur, the so-termed optokinetic nystagmus. They found that nuclei in the midbrain initially control this reflex and that signals from the cerebral cortex (neocortex) are only added later on.

Are these labels read in detail by consumers when making purchases? Do people read only certain portions of the labels? According to a new study published in the November issue of the Journal of the American Dietetic Association, consumers' self-reported viewing of Nutrition Facts label components was higher than objectively measured viewing using an eye-tracking device. Researchers also determined that centrally located Nutrition Facts labels are viewed more frequently and for longer than those located peripherally. http://medicalxpress.com/news/2011-10-consumers-dont-attention-nutrition-fact.html Health Mon, 24 Oct 2011 04:14:30 EST news238648447 A sideline visual test effectively detected concussions in collegiate athletes, according to a team of researchers from the Perelman School of Medicine at the University of Pennsylvania. Concussed athletes scored an average of 5.9 seconds slower (worse) than the best baseline scores in healthy controls on the timed test, in which athletes read a series of numbers on cards and are scored on time and accuracy. This quick visual test, easily administered on the playing field, holds promise as a complement to other diagnostic tools for sports-related concussion. http://medicalxpress.com/news/2011-08-visual-effective-concussions-collegiate-athletes.html Neuroscience Wed, 31 Aug 2011 13:10:36 EST news234015006 A scientist investigating why those with Down syndrome often have poor balance and motor coordination has found that key eye reflexes are substantially altered. http://medicalxpress.com/news/2011-08-cerebella-syndrome.html Medical research Wed, 24 Aug 2011 13:49:57 EST news233412573 Scientists and educators alike have long known that cramming is not an effective way to remember things. With their latest findings, researchers at the RIKEN Brain Science Institute in Japan, studying eye movement response in trained mice, have elucidated the neurological mechanism explaining why this is so. Published in the Journal of Neuroscience, their results suggest that protein synthesis in the cerebellum plays a key role in memory consolidation, shedding light on the fundamental neurological processes governing how we remember. http://medicalxpress.com/news/2011-06-a-better-way-to-remember.html Neuroscience Fri, 17 Jun 2011 14:31:27 EST news227539869
