Ask the average person the street how the brain develops, and they’ll likely tell you that the brain’s wiring is built as newborns first begin to experience the world. With more experience, those connections are strengthened, and new branches are built as they learn and grow.

Gene therapy for hearing loss: Potential and limitations
Regenerating sensory hair cells, which produce electrical signals in response to vibrations within the inner ear, could form the basis for treating age- or trauma-related hearing loss. One way to do this could be with gene therapy that drives new sensory hair cells to grow.
Why do people choke when the stakes are high?
In sports, on a game show, or just on the job, what causes people to choke when the stakes are high? A new study by researchers at the California Institute of Technology (Caltech) suggests that when there are high financial incentives to succeed, people can become so afraid of losing their potentially lucrative reward that their performance suffers.
Action videogames change brains: study
A team led by psychology professor Ian Spence at the University of Toronto reveals that playing an action videogame, even for a relatively short time, causes differences in brain activity and improvements in visual attention.
Is aggressive treatment of severe traumatic brain injury cost effective?
Researchers at the Perelman School of Medicine at the University of Pennsylvania have demonstrated that aggressive treatment of severe traumatic brain injury, which includes invasive monitoring of intracranial pressure (ICP) and decompressive craniectomy, produces better patient outcomes than less aggressive measures and is cost-effective in patients no matter their ageeven in patients 80 years of age. These important findings can be found in the article “Is aggressive treatment of traumatic brain injury cost-effective? Clinical article,” by Robert Whitmore and colleagues, published online March 6 in the Journal of Neurosurgery.
