• 'Big Data' study discovers earliest sign of Alzheimer's development

  12-07-2016 19:02
  Scientists have used a powerful tool to better understand the progression of late-onset Alzheimer's disease (LOAD), identifying its first physiological signs. Rsearchers analyzed more than 7,700 brain images from 1,171 people in various stages of Alzheimer's progression using a variety of techniques including magnetic resonance imaging (MRI) and positron emission tomography (PET).

  Source: ScienceDailyBreastfeeding rates differ among white, black and Hispanic mothers, new American research indicates. This study looked to see if ethnic and racial disparities in breastfeeding could be explained by differences in the use of formula in hospitals, family history of breastfeeding, mother's belief that 'breast is best'; and demographic measures including poverty, education and relationship status.

• Blaming the Victim: Science Examines Why It Happens

  12-07-2016 18:45 via feeds.socialpsychology.org
  Source: Yahoo News - ScienceIn experiments, researchers found that people whose values focus on reducing harm and caring for everyone are likely to blame the perpetrators: the rapist or the police. In contrast, people who adhere more closely to values like loyalty, purity and obedience to authority are more likely to blame the victims.

• East-west asymmetry of jet lag recovery due to oscillation of brain cells

  12-07-2016 17:53
  Travelers frequently report experiencing a significantly slower jet lag recovery after an eastward vs. westward flight. While some are quick to dismiss this complaint as being 'all in their head,' new research suggests it may be caused by the oscillation of a certain type of brain cells.

• Middle-age memory decline a matter of changing focus

  12-07-2016 17:07
  The inability to remember details, such as the location of objects, begins in early midlife (the 40s) and may be the result of a change in what information the brain focuses on during memory formation and retrieval, rather than a decline in brain function.

• Are brain changes fueling overeating in the obese?

  12-07-2016 17:07
  Obese mice are much more likely than lean mice to overeat in the presence of environmental cues, a behavior that could be related to changes in the brain, finds a new study.

• New antidepressant target discovered

  12-07-2016 15:33
  Scientists have shown how manipulating a novel target in the brain using gene therapy could lead to new treatments for depression. Decreasing a set of proteins in the hippocampus reduced depression-like behavior in mice. If replicated in humans, the findings could inform fresh therapies for millions of patients who do not respond to existing treatments for depression.

• Just add water? New MRI technique shows what drinking water does to your appetite, stomach and brain

  12-07-2016 15:33
  Stomach MRI images combined with functional fMRI of the brain activity have provided scientists new insight into how the brain listens to the stomach during eating. Researchers show -- for the first time -- real time data of the brain, the stomach, and people's feelings of satiety measured simultaneously during a meal.

• Western-style diet linked to state-dependent memory inhibition

  12-07-2016 15:24
  Obesity may ultimately be a disease of the brain, involving a progressive deterioration of various cognitive processes that influence eating. Researchers have now shown that memory inhibition -- the useful ability to 'block out' memories that are no longer useful, which depends on a brain area called the hippocampus -- is linked to dietary excess.

• Stress relief by 'comfort foods' may vary between sexes and across the estrous cycle

  12-07-2016 15:23
  Researchers have found that the brain networks that mediate stress relief after eating highly palatable foods may vary between males and females, and may also depend on the stage of the estrous cycle. The study used a rodent model of 'comfort food' to investigate the neurocircuitry behind this phenomenon.

• Overeating in obese mice linked to altered brain responses to food cues

• Brain pathway contributes to restraining from food temptation triggered by environmental cues

  12-07-2016 15:23
  It is often difficult to resist the presentation of a dessert tray or a display of candy bars near a cashier. Eating those excess calories can contribute to overweight and obesity and is often driven by environmental cues -- the sight of beautiful dessert or the colorful wrapper of a candy bar -- rather than metabolic need. Researchers have identified a pathway in the brain responsible for the ability to control this impulsive behavior.
