Two complementary commanders in charge of the brain

A probe of the upper echelons of the human brain's chain-of-command has found strong evidence that there are not one but two complementary commanders in charge of the brain, according to neuroscientists at Washington University School of Medicine in St. Louis.

Research explains why those with obstructive sleep apnea are at higher risk for cardiovascular disease

Researchers have found that patients with obstructive sleep apnea (OSA) have higher levels of a type of dead cells (apoptotic cells) from the lining (endothelium) of their blood vessels circulating in their bloodstream than people who do not have OSA.

Study looks at brain damage that occurs after stroke

Brain damage that occurs even days after a stroke, increasing stroke size and devastation, is the focus of researchers trying to identify new treatments.

Visual short-term memory capacity drops following sleep deprivation

When an air traffic controller at the end of a double shift forgets the location of an aircraft that had recently appeared on his screen, it may be that he did not properly take in the visual information.

No good reason to invest in new fetal oxygen monitor

New technology for measuring blood oxygen levels of a baby during labor which was intended to provide information useful for preventing birth complications, apparently offers no apparent benefit.

Multi-tasking adversely affects brain's learning

Multi-tasking affects the brain's learning systems, and as a result, we do not learn as well when we are distracted, UCLA psychologists report this week in the online edition of Proceedings of the National Academy of Sciences.

Pycnogenol significantly reduces muscular pain

A study published in this month's issue of Angiology shows that supplementation with the pine bark extract Pycnogenol. (pic-noj-en-all) improves blood flow to the muscles which speeds recovery after physical exercise.

Researchers see individual differences in brain activation depending on person's preferences or aversions to risk

Distinct regions of the human brain are activated when people are faced with ambiguous choices versus choices involving only risk, Duke University Medical Center researchers have discovered.

New molecular target for potential drugs to treat acute respiratory distress syndrome

Researchers at the University of Virginia Health System have identified a molecular target, or receptor, for potential drugs to treat acute respiratory distress syndrome (ARDS), a sudden and life-threatening failure of the lung.

Common cardiac sodium channel variant associated with sudden infant death in African Americans

Steve A.N. Goldstein and colleagues from the Pritzker School of Medicine in Chicago have found that a specific mutation, called S1103Y, in a heart protein known as SCN5A is associated with a dramatic, 24-fold increased risk of sudden infant death syndrome (SIDS) in African American infants.

Can marriages be saved by treating snoring?

The husband snores. The wife nudges him to flip over. Both wake up feeling grouchy the next morning. It's a common occurrence that may have more of an impact on the marriage than most couples think.

Acetazolamide improves central sleep apnea in heart failure

Since sleep apnea is associated with heart failure, patients who take a single dose of acetazolamide - a mild diuretic and respiratory stimulant - before going to bed exhibit less sleep apnea, improved blood oxygen levels and fewer daytime symptoms of sleepiness.

Electrical microstimulation allows researchers to map the brain for the first time

Over the last two centuries electrical microstimulation has been often used to demonstrate causal links between neural activity and specific behaviors or cognitive functions. However, to understand the mechanisms by which electrical microstimulation can cause alternations in behaviors and cognitive functions it is imperative to characterize the cortical activity patterns that are elicited by stimulation locally around the electrode and in other functionally connected areas.

Online patient monitoring

Drivers know whether or not their cars are running properly by observing the dashboard. Physicians can check vital parameters such as the pulse even when their patients are at home. The data can be recorded with the wireless monitoring device VitaSENS.

Surprising autism finding

New brain imaging research at the University of North Carolina at Chapel Hill indicates that when people with autism look at a face, activity in the brain area that responds is similar to that of people without autism.

Gender affects the way a person's brain responds to humor

Need more evidence that men and women are different? Look no further than the Sunday funnies. According to a new Stanford University School of Medicine study, gender affects the way a person's brain responds to humor.

New device offers potential for accurate and reliable monitoring of brain oxygenation during cardiac surgeries

A new device that uses near-infrared light to non-invasively monitor the oxygenation of the brain during surgery appears to be a promising alternative to the more invasive techniques currently in use, according to a new study by Duke University Medical Center anesthesiologists.
