A team of ear, nose and throat specialists and neurosurgeons at the University Hospital of Navarra, led by doctors Manuel Manrique Rodríguez, specialist in ear, nose and throat surgery and Bartolomé Bejarano Herruzo, specialist in paediatric neurosurgery, have successfully operated on a 13 month-old girl from Murcia, who had been born deaf due to the lack of auditory nerves.

A new way of generating brain cells has been uncovered in Drosophila. The findings, published this week in the online open access journal Neural Development, reveal that this novel mode of neurogenesis is very similar to that seen in mammalian brains, suggesting that key aspects of neural development could be shared by insects and mammals.

Boosted by physical and mental exercise, neural stem cells continue to sprout new neurons throughout life, but the exact function of these newcomers has been the topic of much debate. Removing a genetic master switch that maintains neural stem cells in their proliferative state finally gave researchers at the Salk Institute for Biological Studies some definitive answers.

The human brain contains its own store of a powerful enzyme (and stroke drug) called tissue plasminogen activator (tPA), which appears to be a key regulator of blood flow to brain cells, a team at the Weill Cornell Medical College in New York City reports.

At its core, healthy neurological function hinges on the efficient passage of information between brain cells via the synapse.

For the first time, scientists at Weill Cornell Medical College in New York City have observed in real time a cellular mechanism that's crucial to how brain cells communicate.

Measures to protect astronauts from health risks caused by space radiation will be important during extended missions to the moon or Mars, say researchers in a paper currently online in Experimental Neurology.

It’s a general belief that the circuitry of young brains has robust flexibility but eventually gets “hard-wired” in adulthood. As Johns Hopkins researchers and their colleagues report in the Nov. 8 issue of Neuron, however, adult neurons aren’t quite as rigidly glued in place as we suspect.

Newly created neurons in adults rely on signals from distant brain regions to regulate their maturation and survival before they can communicate with existing neighboring cells—a finding that has important implications for the use of adult neural stem cells to replace brain cells lost by trauma or neurodegeneration, Yale School of Medicine researchers report in The Journal of Neuroscience.

Researchers have identified a compound in tree bark that mimics the chemical reactions of a naturally occurring molecule in the brain responsible for stimulating neuronal cell signaling. Neuronal cell signaling plays a crucial role in the growth, plasticity and survival of brain cells.

The fragile head and brain of a fly are not easy things to examine but MRC scientists have figured out how to make it a little simpler. And they hope their research will shed light on human disease.

Researchers at the University of Illinois have developed a method for culturing mammalian neurons in chambers not much larger than the neurons themselves. The new approach extends the lifespan of the neurons at very low densities, an essential step toward developing a method for studying the growth and behavior of individual brain cells.
