|Watching the developing brain, scientists glean clues on neurological disorder|
|Tuesday, November 13, 2012|
As the brain develops, each neuron must find its way to precisely the right spot to weave the intricate network of links the brain needs to function. Like the wiring in a computer, a few misplaced connections can throw off functioning for an entire segment of the brain.
A new study by researchers at the University of North Carolina School of Medicine reveals how some nerve cells, called interneurons, navigate during the development of the cerebral cortex. Mutations in a key gene behind this navigation system underlie a rare neurological disorder called Joubert syndrome; a condition linked with autism spectrum disorders and brain structure malformations.

Obama defends Obamacare: 'We will make this work'
President Barack Obama on Tuesday launched a planned three-week-long push for — and defense of — his embattled health-care reform law, vowing to "make this work"… But Dr. Sam Weir, a physician cited by Obama in his speech for his support of the Affordable Care Act, told CNBC.com that "many of my patients are looking forward to getting coverage."…"From where I sit, anything that expands coverage of people who have to make choices about what medicines to take because they can't afford them, or they end up in the emergency room because haven't gotten the preventative care they need, those are important steps in terms of health care policy," said Weir, medical director of family medicine at the University of North Carolina School of Medicine.
