Kessler Foundation Research Center Presented Two Studies on Post-stroke Spatial Neglect at American Academy of Neurology

Studies May Identify Best Candidates for Treatment of this Hidden Disability WEST ORANGE, N.J., April 30 /PRNewswire/ -- Two studies from Kessler Foundation Research Center's Stroke Rehabilitation Research Laboratory were presented today at the American Academy of Neurology (AAN) 61st Annual ...

Physical fitness improves spatial memory, increases size of brain structure

When it comes to the hippocampus, a brain structure vital to certain types of memory, size matters. Numerous studies have shown that bigger is usually better. Now researchers have found that elderly adults who are more physically fit tend to have bigger hippocampi and better spatial memory than th...

Sex difference on spatial skill test linked to brain structure

Men consistently outperform women on spatial tasks, including mental rotation, which is the ability to identify how a 3-D object would appear if rotated in space. Now, a University of Iowa study shows a connection between this sex-linked ability and the structure of the parietal lobe, the brain re...

Psychologists report that a gender gap in spatial skills starts in infancy

Men tend to perform better than women at tasks that require rotating an object mentally, studies have indicated. Now, developmental psychologists at Pitzer College and UCLA have discovered that this type of spatial skill is present in infancy and can be found in boys as young as 5 months old. ...
