2012 Press Releases

  • Changes in Sleep Architecture Increase Hunger, Eating

    Released October 22, 2012 - In a new study, researchers have found that adolescents’ blood levels of various micronutrients are correlated with how well they performed in certain physical fitness tests. Though these results don’t prove causality, they suggest a new relationship between different measures of adolescent health.
  • Obstructive Sleep Apnea’s Damage Evident After One Month

    Released April 23, 2012 - Texas researchers have developed a unique model that mimics obstructive sleep apnea (OSA) in humans. This approach has found that after just 30 days of OSA exposure, cerebral vessel function is altered, which could lead to stroke.
  • Changes in Brain’s Blood Flow Could Cause ‘Brain Freeze’

    Released April 22, 2012 - Using ‘brain freeze’ as a proxy for headaches, researchers find a specific artery of particular interest.
  • Oxygen-Deprived Baby Rats Fare Worse If Kept Warm

    Released February 13, 2012 - A new study suggests that baby rats deprived of oxygen, but kept warm, had bigger swings in glucose and insulin, metabolic and physiologic effects that could increase the chances of brain damage. The findings could have implications for premature infants, who often suffer from hypoxia.
  • Working Memory and the Brain

    Released February 6, 2012 - Work published in the Journal of Neurophysiology may explain why people can hold visual information in high detail in their working memory. Using functional neuroimaging, investigators found that visual working memory follows a more general pattern of brain activity than visual perception and relies on concerted action of specialized areas in the rear of the brain and control areas in the front of the brain, which were activated regardless of what the participants viewed.
