A team of neuroscientists and engineers are working to develop a new form of treatment for people who have Parkinson’s disease, depression, or obsessive-compulsive disorder. According to a recent New York Times article, the available methods for treating these conditions currently involve the risks of surgery and can have limited ability with directing electrical pulses to the right areas of the brain.
Dana Alliance member Helen Mayberg, tells the Times:
They have this clever new way to deliver current[s] to a spot of interest deep in the brain and do it without invading the brain…If you didn’t have to actually open up somebody’s brain and put something in it, if it could do what we’re doing now just as well—sign me up.
So far the research has only been conducted in mice, but experts are hoping the technique will work for people, too. “This is something that many of us in the field have wished for for a long time,” says Alexander Rotenberg. Rotenberg is director of the neuromodulation program at Boston Children’s Hospital and Harvard Medical School. The article goes on to explain the details of the non-invasive treatment:
The method, called temporal interference, involves beaming different electric frequencies, too high for neurons to respond to, from electrodes on the skull’s surface. The team found that where the currents intersected inside the brain, the frequencies interfered with each other, essentially canceling out all but the difference between them and leaving a low-frequency current that neurons in that location responded to.

Early world explorers worked with crude maps, painfully charting the geography of new locations for future generations. Today, anyone can log on to the internet for detailed descriptions of the countries, cities, and roads of our world. In comparison, the map of the brain still has a long way to go. In fact, a map of the brain made over 100 years ago is still being used by neuroscientists today.
“Cartographers of the Brain: Mapping the Connectome,” a discussion at the World Science Festival in New York City, focused on efforts by neuroscientists to create new, more detailed maps of the brain. Deanna Barch, Washington University School of Medicine; Nim Tottenham, Columbia University; Dana Alliance member Jeff Lichtman, Harvard University; and Dana Alliance member David Van Essen, Washington University, formed the expert panel.
What if life expectancy expanded and we could live into our nineties and beyond in relative good health? That was one of the crucial questions debated in “Engineering Immortality,” a panel discussion at last week’s World Science Festival in New York City.
In introducing the sold-out program at NYU’s Global Center, host and ABC-TV news correspondent Bill Blakemore pointed out that American life expectancy has gone from 47 to 79 years in just a century. “Today’s scientists are growing hearts in the lab, creating organs with 3-D bio-printers, and eliminating cells that shorten life,” he said. “Will this new technology yield another dramatic increase in life expectancy?”
Who wouldn’t enjoy an extra hour or two of sleep before climbing out of bed and getting ready for work? A good night’s rest, or lack thereof, not only contributes to the following day’s productivity levels and emotions, but also its long-term effects are linked to cognitive and cardiovascular health. According to the National Institutes of Health (NIH), one third of Americans get less than seven hours of sleep each night, and research points sleeping less than seven to eight hours each night to health risks such as stroke, obesity, cancer, and high blood pressure.
For National Sleep Awareness Week (April 23 – 29), we asked sleep expert Clifford B. Saper, M.D., Ph.D., to discuss the importance of sleep hygiene, sleep disorders, and current research at Harvard Medical School’s Division of Sleep Medicine, where he conducts his lab research and heads the neurology department. Saper is also a Dana Alliance for Brain Initiatives member and past Dana Foundation grantee.
