Maiken Nedergaard, M.D., D.M.Sc., has been elected a member of the Royal Danish Academy of Sciences, the premier scientific society in Denmark. The society elects only six new members worldwide every other year.
Nedergaard has been a pioneer in brain research, demonstrating that brain cells known as astrocytes play a role in a host of human diseases. For decades, much of the attention of neuroscientists had been focused on brain cells known as neurons, which send electrical signals. Astrocytes were long considered cells whose primary function was to support the neurons.
Nedergaard has turned that notion on its head, showing that astrocytes themselves play an important role in epilepsy, spinal cord disease, migraine headaches, stroke, and Alzheimer's disease.

A brain chemical that makes us sleepy also appears to play a central role in the success of deep brain stimulation to ease symptoms in patients with Parkinson's disease and other brain disorders. The surprising finding is outlined in a paper published online Dec. 23 in Nature Medicine.
The work shows that adenosine, a brain chemical most widely known as the cause of drowsiness, is central to the effect of deep brain stimulation, or DBS. The technique is used to treat people affected by Parkinson's disease and who have severe tremor, and it's also being tested in people who have severe depression or obsessive-compulsive disorder.
Patients typically are equipped with a
brain pacemaker,a small implanted device that delivers carefully choreographed electrical signals to a very precise point in the patient's brain. The procedure disrupts abnormal nerve signals and alleviates symptoms, but doctors have long debated exactly how the procedure works.
Certainly the electrical effect of the stimulation on neurons is central to the effect of deep brain stimulation,said Maiken Nedergaard, M.D., Ph.D., the neuroscientist and professor in the Department of Neurosurgery who led the research team.
But we also found a very important role for adenosine, which is surprising.

U.S. Navy Awards Grant to Study Neural Effects of Underwater Sound to John Olschowka, Ph.D. and Diane Dalecki, Ph.D.
John Olschowka (PI, Dept. of Neurobiology & Anatomy) and Diane Dalecki (co-I) received a two-year grant from the U.S. Navy titled
Neural Effects of Underwater Sound.Underwater sound fields are used for numerous commercial and military applications, including imaging, oil exploration, mapping the ocean, and harbor surveillance. Sponsored by the U.S. Navy, Drs. Olschowka and Dalecki have embarked on a new collaborative project that will investigate the interactions of continuous and impulsive underwater sound fields with the brain and spinal cord. The Olschowka lab, in the UR Department of Neurobiology and Anatomy, has long-standing expertise in examining injury to neural tissues, including trauma, using molecular, protein, and immunohistochemical techniques. Using the acoustic sources and technical expertise of the Dalecki lab, the team will investigate neural bioeffects of sound fields at frequencies ranging from 500 Hz–30 kHz. To also study the effects of acoustic impulses, the facilities and expertise available at Hydroacoustic, Inc. will be employed to generate underwater impulsive sound fields using an air gun system. Neural tissues of animals exposed to these continuous and impulsive underwater sound fields will be assessed for vascular damage, axonal injury, and glial activation. Results of this project will help to establish safe exposure guidelines for human divers and marine life exposed to underwater sound fields.

More than a dozen Rochester scientists seeking ways to reverse or lessen the effects of paralysis and other effects of spinal cord injury will begin new projects and continue promising research, thanks to motorists in New York State who push the gas medal a little too far.
Three research projects at the University of Rochester Medical Center are among the programs funded this year through the Spinal Cord Injury Research Program run by the New York State Department of Health. The program, created in 1998, uses fines paid by speeding motorists to fund research into spinal cord injury, whose number-one cause nationwide is motor vehicle accidents. In Rochester this year the grants are going to Roman Giger, Ph.D.; Maiken Nedergaard, M.D., Ph.D.; and Mark Noble, Ph.D.

By blowing gentle puffs of air onto a mouse's whiskers and watching how its brain reacts, scientists are discovering that a long-overlooked signaling system in the brain is crucial to our everyday activity.
The work is the latest in a growing body of evidence that star-shaped brain cells known as astrocytes aren't simply support cells but are stars of the brain in their own right, say researchers at the University of Rochester Medical Center who did the study. The work will be reported in a paper in the June issue of Nature Neuroscience and is now available online.
Now people have to take astrocytes seriously,said Maiken Nedergaard, M.D., Ph.D., professor in the Department of Neurosurgery and a member of the Center for Aging and Developmental Biology, whose team did the research. In the past few years she has found that the cells, long thought to simply nourish other cells and clean up their wastes, are central to diseases like epilepsy, spinal cord injury, and maybe even Alzheimer's disease.

As part of a five-year, $3.5 million grant from the National Institutes of Health (NIH), researchers will look at whether a breakthrough therapy for Parkinson's disease can also treat the worst cases of obsessive compulsive disorder (OCD). A research team led out of the University of Rochester Medical Center will measure whether Deep Brain Stimulation (DBS) can reduce the rampant anxiety that keeps some OCD patients homebound.
DBS is one of the most promising areas of OCD research because early studies show that it may help many within the approximately 20 percent of OCD patients for whom neither psychological nor drug therapy works,said Suzanne Haber, Ph.D., a professor within the Department of Pharmacology and Physiology at the University of Rochester School of Medicine and Dentistry.
Some patients have been able to venture out to work and school for the first time with DBS,said Haber, who is lead investigator for the grant.

New findings that long-overlooked brain cells play an important role in regulating blood flow in the brain call into question one of the basic assumptions underlying today's most sophisticated brain imaging techniques and could open a new frontier when it comes to understanding Alzheimer's disease.
In a paper to appear in the February issue of Nature Neuroscience and now available on-line, scientists at the University of Rochester Medical Center demonstrate that star-shaped brain cells known as astrocytes play a direct role in controlling blood flow in the brain, a crucial process that allows parts of the brain to burst into activity when needed. The finding is intriguing for a disease like Alzheimer's, which has long been considered a disease of brain cells known as neurons, and certainly not astrocytes.
For many years, astrocytes have been considered mainly as housekeeping cells that help nourish and maintain a healthy environment for neurons. But it's turning out that astrocytes may play a central role in many human diseases,said neuroscientist Maiken Nedergaard, M.D., Ph.D., who has produced a string of publications fingering astrocytes in diseases like epilepsy and spinal cord injury.

Star-shaped brain cells that are often overlooked by doctors and scientists as mere support cells appear to play a key role in the development of epilepsy, researchers say in a study published on-line August 14 in Nature Medicine. It's one of the first times scientists have produced firm evidence implicating the cells, known as astrocytes, in a common human disease.
Scientists found that astrocytes can serve as ground zero in the brain, setting off a harmful cascade of electrical activity in the brain by sending out a brain chemical that triggers other brain cells to fire out of control.
While it's impossible to tell at this early stage what effect the finding will have on treatment, the investigators at the University of Rochester Medical Center are hopeful the results will give doctors and pharmaceutical firms a new target in efforts to treat and prevent the disease.
This opens up a new vista in efforts to treat epilepsy. It might be possible to treat epilepsy not by depressing or slowing brain function, as many of the current medications do, but by targeting brain cells that have been completely overlooked,says Maiken Nedergaard, M.D., Ph.D., professor in the Department of Neurosurgery and a researcher in the Center for Aging and Developmental Biology, who led the research.
We are hopeful that someday, this will be very beneficial to patients.

ATP, the vital energy source that keeps our body's cells alive, runs amok at the site of a spinal cord injury, pouring into the area around the wound and killing the cells that normally allow us to move, scientists report in the cover story of the August issue of Nature Medicine.
The finding that ATP is a culprit in causing the devastating damage of spinal cord injury is unexpected. Doctors have known that initial trauma to the spinal cord is exacerbated by a cascade of molecular events over the first few hours that permanently worsen the paralysis for patients. But the finding that high levels of ATP kill healthy cells in nearby regions of the spinal cord that were otherwise uninjured is surprising and marks one of the first times that high levels of ATP have been identified as a cause of injury in the body.
While the work opens up a promising new avenue of study, the work is years away from possible application in patients, cautions Maiken Nedergaard, M.D., Ph.D., the researcher who led the study. In addition, the research offers promise mainly to people who have just suffered a spinal cord injury, not for patients whose injury is more than a day old. Just as clot-busting agents can help patients who have had a stroke or heart attack who get to an emergency room within a few hours, so a compound that could stem the damage from ATP might help patients who have had a spinal cord injury and are treated immediately.
