  • Thinking Makes It So: Science Extends Reach of Prosthetic Arms

    Released November 11, 2007 - Motorized prosthetic arms can help amputees regain some function, but these devices take time to learn to use and are limited in the number of movements they provide. A researcher has pioneered a technique known as targeted muscle reinnervation (TMR), which allows a prosthetic arm to respond directly to the brain’s signals, making it much easier to use than traditional motorized prosthetics.
  • Acute Sleep Deprivation Leads To Changes In Nighttime Urine Production

    Released August 8, 2007 - Our body’s production of urine follows a circadian rhythm. During the day, we experience greater urinary frequency; at night, urine production declines, enabling us to get uninterrupted sleep. The regulation of urine excretion during nighttime hours is influenced by many factors, including hormones, blood flow, and sleep-related factors. The mechanism behind the day/night changes is not yet clear. Danish researchers who have examined the urinary patterns of sleep-deprived volunteers have found that a lack of sleep leads to increased urinary output and more salt in the urine. The findings were found to be more prevalent in males than females.
  • Hormone That Signals We Are Full When Eating Also Curbs Fast Food Consumption And Tendency To Binge Eat

    Released June 7, 2007 - The synthetic form of a hormone previously found to produce a feeling of fullness when eating and reduce body weight, also may help curb binge eating and the desire to eat high-fat foods and sweets. The findings on fast food consumption and binge eating tendencies are based on a 6-week research study of 88 obese individuals.
  • Patients Smelling For First Time In Their Lives

    Released April 30, 2007 - New discoveries about the biochemical basis of the majority of cases involving congenital smell loss.
  • Your Brain And Hormones May Conspire To Make You Fat

    Released April 30, 2007 - Physiologists are unraveling the role that hormones and the brain play in urging you to eat more than you should. Some people’s hormones may be signaling their brains to send messages like “Eat a lot now,” and “Go for the fat and sugar.”
  • Role of Mid-Brain In Integrating Heart & Respiratory Response To Exercise

    Released April 29, 2007 - Oxford University researchers have examined several deep brain nuclei during exercise and concluded that the periaqueductal grey area (PAG), the small-celled gray matter adjoining or surrounding the cerebral aqueduct and the third ventricle in the midbrain, contains the greatest number of neural changes in connection with anticipation of exercise. The findings provide direct evidence implicating the PAG as a key area of the brain’s circuitry’s affecting cardiorespiratory response to exercise.
  • Erectile Dysfunction In Diabetes Is Due To Selective Defect In The Brain

    Released March 15, 2007 - A new study sheds additional light on how erectile dysfunction (ED) interacts with diabetes. The study is another step in uncovering the link between the two disorders, and may lead to improved efficacy in treatments.
