Marcos Frank, PhD, associate professor of Neuroscience at the University of Pennsylvania School of Medicine, will present information on early brain development and the importance of sleep during early life when the brain is rapidly maturing and highly changeable. view more (2010-02-22)
Babies and sleep: Another reason to love naps
Anyone who grew up in a large family likely remembers hearing "Don't wake the baby." While it reinforces the message to older kids to keep it down, research shows that sleep also is an important part of how infants learn more about their new world. view more (2010-02-22)

Severe sleep apnea decreases frequency of nightmare recall
A study in the Feb. 15 issue of the Journal of Clinical Sleep Medicine shows that patients with severe obstructive sleep apnea (OSA) report a significantly lower frequency of nightmares than patients with mild or no sleep apnea, indicating that OSA suppresses the cognitive experience of nightmare recall. view more (2010-02-16)

However, listening to one or two hours of... view more... (2010-02-09)
