The brain undergoes a dramatic shift at birth by controlling a “pump” that drains chloride out of newborn neurons, making these highly chaotic, developing cells quiet down. Researchers at Duke University Medical Center have figured out the genetic control of the pump in rodents. These findings may ultimately benefit people who suffer from the neuron misfirings that occur in epilepsy and neuropathic pain, Wolfgang Liedtke says.
DUKE (US)—At the moment a newborn switches from amniotic fluid to breathing air, another profound shift occurs: nerve cells in the brain convert from hyperexcitability to a calm frame against which outside signals can be detected. Continue…

Zebrafish do it. Why can’t we?
U. MICHIGAN (US)—Biologists long have marveled at the ability of some animals to re-grow lost body parts—newts regrow legs and zebrafish re-grow fins—and even repair damaged heart and eye tissue. Now researchers have discovered that some of the same genes underlie the process in different types of tissues. (more…)

Drug improves mobility for some MS patients
U. ROCHESTER (US)—A drug that has shown promise treating a debilitating symptom of multiple sclerosis (MS) is one step closer to market. Newly released findings from clinical trials in the United States and Canada show the experimental drug fampridine improves walking ability in some patients.
