Our visual system may react more rapidly when visualising 2 objects which might collide
International research co-led by professor Alejandro Maiche, of the Department of Basic, Evolutionary and Educational Psychology at the UAB, has put forward the hypothesis that the brain responds to the possibility that two objects might collide, in a different way to how it would react to two objects in movement with divergent trajectories. view more (2007-09-14)
Distinguishing between 2 birds of a feather

Scientists unmask brain's hidden potential
Previous research has found that when vision is lost, a person's senses of touch and hearing become enhanced. But exactly how this happens has been unclear. view more (2008-08-27)
How Well Informed Are HIV Research Volunteers Giving 'Informed Consent'?
Pregnant women may be volunteering to participate in HIV research without fully understanding the benefits or consequences, according to a study published today in BMC Medicine. Volunteers' comprehension of studies or treatments should be tested to ensure that their consent is truly informed and voluntary, say the study's authors. International... view more... (2004-08-02)
Training and experience can affect brain organization, research shows
New research comparing music conductors and non-musicians shows that both the conductors and the non-musicians "tuned out" their visual sense while performing a difficult hearing task. view more (2007-11-05)
Dyslexia varies across language barriers

Brain innately separates living and non-living objects for processing
For unknown reasons, the human brain distinctly separates the handling of images of living things from images of non-living things, processing each image type in a different area of the brain. view more (2009-08-14)
Experimental treatments restore partial vision to blind people
Two experimental treatments, a retinal prosthesis and fetal tissue transplant, restored some vision to people with blinding eye diseases. The findings, presented at Neuroscience 2009, the annual meeting of the Society for Neuroscience and the world's largest source of emerging news on brain science and health, may lead to new treatments for the... view more...

MSU researcher helps develop computer game for Ugandan children recovering from cerebral malaria
The computer program Captain's Log - originally used with individuals diagnosed with attention deficit hyperactivity disorder, brain injuries or learning disabilities - is being adapted to rehabilitate Ugandan children who are survivors of cerebral malaria. view more (2007-10-24)
New Treatment Improves Visual Acuity Score of Patients with Retinitis Pigmentosa
Neurotech SA announced positive results from an open-label Phase I clinical trial (03-EI-0234) of its lead product, NT-501. NT-501 uses Neurotech's patented Encapsulated Cell Technology (ECT) as a device to deliver ciliary neurotrophic factor (CNTF) to eyes of visually impaired patients with retinitis pigmentosa (RP). Neurotech is a biotechnology... view more... (2005-05-04)
Dementia on the rise in aging populations
Life expectancy continues to rise in most countries around the world, and in industrialized nations it is not uncommon for people to live well into their 90s. One consequence is that dementia will become much more common. view more (2006-10-31)
'Twinkle after effect' can help retinal patients detect vision loss quickly and cheaply

Former child soldiers of Nepal at increased risk for range of mental health problems
In Nepal, former child soldiers display greater severity of mental health problems, such as symptoms of posttraumatic stress disorder (PTSD) and depression, compared with children who were not forced into military service, according to a study in the August 13 issue of JAMA, a theme issue on violence and human rights. view more (2008-08-13)
High fruit and vegetable intake positively correlated with antioxidant status, cognitive performance
Researchers at the Institute of Biochemistry and Molecular Biology I of the Heinrich-Heine University, Düsseldorf, Germany, investigated the relationship between fruit and vegetable intake, plasma antioxidant micronutrient status and cognitive performance in healthy subjects aged 45 to 102 years. view more (2009-09-09)
