Barn Owls Help Explain How the Brain Pays Attention
By studying barn owls, scientists believe they've taken an important step toward solving the long-standing mystery of how the brain chooses what most deserves attention. The finding likely applies to all animals, including humans, and offers new insight into what goes wrong in brains of people who have attention-deficit/hyperactivity disorder.

Astrocytes Can Alter Myelin Thickness to Change Neuronal Transmission Speed
The transmission speed of neurons fluctuates in the brain to achieve an optimal flow of information required for day-to-day activities, suggests a new study. The results, appearing in PNAS, suggest that astrocytes alter the transmission speed of neurons by changing the thickness of myelin.
