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…
