Researchers find that manipulating a region in the hypothalamus dramatically extended the lifespan of mice. Might such a tweak extend life and health in humans, too?

There are many possible reasons why so many people who have Alzheimer’s also show increased insulin resistance. If researchers could tease out the mechanism, they might find that a current drug or treatment for diabetes would work on dementia, as well.

A Q&A with researcher Abigail Marsh on how developing empathy shapes emotional health, impacts violence and may be changing our views on crime and punishment.

Some people with Parkinson’s disease or intractible depression have shown great improvement using implanted and external brain stimulation. Now researchers are diving down, to improve treatment methods and to discover what, exactly, stimulating the brain does.

Bexarotene’s promising results in mice are not fully replicated; IVIG antibodies fail to impress in a phase 3 clinical trial.

Research suggests that non-invasive techniques such as transcranial magnetic stimulation and transcranial direct current stimulation might enhance sporting performance. This has not been confirmed yet, however, and even if it is, it would probably be considered as unacceptable as taking performance-enhancing drugs.

More than 1 million Americans are legally blind and another 10% cannot detect light. With increased mean lifespan, the frequency of age-related eye disease will double in the next 30 years. A significant percentage of the non-treatable blindness stems from loss of photoreceptors (the rods and cones). Once photoreceptors are lost, restoring useful vision to blind patients has been impossible.

Researchers hope that the ‘5:2 diet’ and other eating-restriction techniques can prevent age-related neurodegeneration and extend the working life of the brain

For some people, trying LSD or Ecstasy (MDMA) can leave a legacy of chronic visual hallucinations.

Researchers are discovering medicines and methods that could enhance, dampen, or erase memories. At the recent BNA Festival of Neuroscience, ethicists and scientists considered the implications of modifying the mental record during a process called memory reconsolidation.

At a recent New York Academy of Sciences meeting, researchers presented data suggesting that targeting glutamate in the brain could help people who don’t respond to current therapies.

There is an age-old adage that nature and nurture combine to control all aspects of an individual’s functioning, including risk for disease. Research over the past decade, in a still relatively new field called epigenetics, has provided a sophisticated understanding of how this occurs.

The brain can regain language abilities even years after a stroke—and training the toughest language tasks, not the easiest, first may be the best recovery strategy.

Researchers and device-makers seek to quickly put their discoveries to use in a way that patients will prefer. “You can have the best technology but if the patient doesn’t want to use it or wear it, it all ends there.”

The path to disease in the brain may not be the same for all, or even many, of the people diagnosed with such disorders as schizophrenia or autism. And now researchers have found that the same pathways may underlie very different disorders.

The movie Men in Black ends with a sequence where Tommy Lee Jones’ character is reported in the popular press to have awakened miraculously after 20 years in a coma. Although clinicians traditionally have scoffed at such reports, such cases do make the news now and again, and raise the question of whether and how that can happen. Recent advances provide some answers, and suggest some treatments that might promote such an outcome.

Researchers find people who can not anticipate fear because of a rare disease can still experience it in real-time. This suggests a more-complex role for the amygdala and other fear-sensing circuits.

Researchers are starting to explore links between genetic variation and a how a person responds to certain psychiatric therapies. Perhaps someday your doctor will say, "There's an X probablility you'll respond to this therapy."

High-pressure doses of rich oxygen can improve brain function in injured animals, but early research is mixed in humans. Is it the pressure? The extra oxygen? Or simply a placebo effect?
