Neuroscience 2009 highlights new research on exercise, music and the brain

Research presented today at Neuroscience 2009, the annual meeting of the Society for Neuroscience (SfN) and the world's largest source of emerging news about brain science and health, provides a better understanding of the brain, nervous system, and related disorders.

Specific research released today shows:

• The benefits of exercise on both the brain and body, and, more specifically, underscores the positive influence of regular physical activity on Parkinson's disease, depression, premenstrual syndrome, and memory.
  
• New tools are enabling researchers to identify neural similarities and differences between species. The findings may help to explain faculties, like language, and diseases, like Parkinson's, that are unique to humans.
  
• New insights into male behavior support the idea that many gender differences lie in the brain and are influenced by both genes and environment.
  
• Scientists are developing novel ways to bypass the blood-brain barrier, a network of blood vessels that prevents more than 95 percent of all chemicals from entering the brain from the bloodstream. Researchers describe new methods for transporting drugs across the BBB as well as ways to enhance the brain's own immune response, which is separated from the body's immune system by the BBB.
