White Matter and Learning in the Brain (MP3 - 03:53, 3.5 MB)
The brain is composed of two different types of tissue: gray matter and white matter. Traditionally, neuroscientists who have studied learning and memory have focused their attention on synaptic processes between neurons (found in gray matter) and consequently have largely ignored the role that glia and axons (found in white matter) play in facilitating learning and memory processes. Research funded by Eunice Kennedy Shriver National Institute of Child and Health Development (NICHD) demonstrates that white matter plays a more important role in learning may have previously been thought.

Newer Heart Surgery for Infants Offers First-Year Survival Benefit over Traditional Procedure (MP3 - 03:40, 3.4 MB)

The study is the largest comparative effectiveness study for congenital heart disease and the first North American multi-center randomized trial of congenital heart disease.

Long life in the 21st Century (MP3 - 04:05, 3.7 MB)
A research team has found a genetic variant that may contribute to violently impulsive behavior. Impulsive behavior, or actions without foresight, is a factor in many pathological behaviors—including suicide, aggression, and addiction—but it is also a trait that can be of value if a quick decision must be made or in situations where risk-taking is favored.
