...rain and behavioral abnormalities, such as autism, mental retardation, and poor coordination" said the UCSD paper's senior author, Joseph Gleeson, M.D., assistant professor of neurosciences at UCSD and Children's Hospital San Diego. This identification caps a five-year hunt for the first gene for Joube...

Mouse study: 'Critical' Down syndrome region isn't

...0 live births, is the most common genetic cause of mental retardation and congenital heart disease. "The simplistic idea that just one of the hundreds of genes on chromosome 21 affects development no longer holds up," says Roger Reeves, Ph.D., professor of molecular biology and genetics in Johns Hopkins' I...

Singled out: Spotting mutant neurons in normal brains offers clues to Fragile X

...le X Syndrome is the most common type of inherited mental retardation. Since the early 1990's, it has been known that the disease results from the loss of a single gene and, for the last several years, that the Fragile X gene product regulates the expression of other proteins. However, the link between this...

Psychologist finds instance where 'two wrongs do make a right'

EUGENE, Ore. -- A trusted mental map of your surroundings turns out to be slightly misaligned, skewing your orientation. Your ability to control the direction in which you move is similarly compromised, although in a manner opposite the map's offset. Taken together, the errors cance...

Evidence that learning is consolidated during sleep

The researchers' comparisons of the brain activity in the groups confirmed that the hippocampal activity they detected was due to spatial processing. "Our results provide critical evidence that spatial memory traces are processed during N...

Through electronic sensors, the system tracks the position of the X-ray gantry and patient table, and thus, the location of the X...

Children's Hospital Boston launches major genetic study of autism

Further studies of MeCP2 and related genes will explore how they work and how brain-cell activity triggers them. These investigations may uncover other genes and biochemical pathways that underlie autism. Childre...
